Pro/WELDING Using Welding

About Welding With Welding you can: •

Create and modify simple and compound welds in an Assembly. Weld geometry can be solid or light.

•

Prepare edges for welding and create weld notches.

•

Hide or display welds in an assembly.

•

Define parameters of the welding process.

•

Create assembly drawings with welding symbols.

•

Obtain both general and specific information about welds, including location, mass, volume, and size.

•

Generate Pro/REPORT tables with rod and weld information

A typical Welding session may include the following steps: 1. Import the reference part into the welding environment by entering Assembly mode and retrieving or creating an assembly. 2. Define the welding environment by defining welding rods, processes, and parameters. 3. Determine if you want to weld, prepare edges, or create weld notches, or a combination of the three. 4. Define the type of weld, edge preparation, or notch to perform on the part or assembly. 5. Determine the family table configuration. The family table provides the functionality to create the cut in either the generic or instances of the part and its assemblies. 6. Determine if you want your weld or feature to contain solid or light geometry. 7. Define the edge preparation cut, notch, or weld dimensions. 8. Set any additional parameters or welding processes. 9. Detail your welding assembly with drawings of welded assemblies and annotate weld joints. 10. Generate either a bill of materials (BOM) or Pro/REPORT tables with weld parameters, or both.

To Get Started with Welding 1. Create or open an assembly in Pro/ENGINEER. 1

Pro/WELDING Help Topic Collection

2. Click Applications > Welding. You may see (toolbar to right of graphics window). 3. If you do not see

appear in the Right Toolchest

, follow these steps:

a. Click Tools > Customize Screen. b. In the Categories list, select Weld Feature. Under Commands, appears. c. Drag

to the Right Toolchest or Top Toolchest.

4. Start to create your welds: o

Click or Insert > Weld to open the WELD DEFINITION dialog box so you can define the Weld, Edge Preparation, or Weld Notch welding features. You can define one feature, or a combination of welding features at the same time.

o

Click Tools > Weld to create and define welding rods, processes and parameters.

Understanding the Welding Interface

About the Welding Interface The Welding user interface contains the following elements. Refer to Fundamentals Help for greater detail on the Pro/ENGINEER user interface: •

Menu Commands Welding menu commands are grouped, and open dialog boxes or submenus for step-by-step weld creation.

•

Welding Dialog Boxes o

Expandable and collapsible dialog boxes sections are indicated by a black triangle. When you click the triangle, a section expands or collapses.

o

Enables you to define attributes of your welding operation by separating major groupings within a dialog box.

o

Enables you to simultaneously create or modify multiple welding features and feature types.

o

Provides dynamic options that update as you make selections.

About the Model Tree with Welding The Model Tree provides a feature-level visual representation of your welding project. Each feature you create is chronologically represented in the Model Tree. Highlights of the Model Tree follow. Refer to Fundamentals Help for greater detail on the Pro/ENGINEER user interface.

2

Pro/WELDING

Using the Model Tree, you can: •

Make features more visible by highlighting them.

•

Reorder features, and ultimately change the project dynamic, by dragging features to various locations.

•

Access a shortcut menu that enables you to create and modify your design. The shortcut menu may include commands to: o

Edit and edit the definition of welding features.

o

Hide or unhide, suppress or resume, welding features to simplify or accentuate areas of your welding design.

o

Meet your design intent quickly by using the Pattern tool to pattern weld features.

o

Obtain information, and create notes about welding features.

o

Convert light welding geometry to solid geometry (and vice versa).

o

Edit parameters.

You can define which features display and how they display in the Model Tree, by clicking the Show and Settings tabs.

About Using Layers in Welding You use layers in a model or a layout as an organizational tool. By associating items with a layer, you can collectively manipulate features including deleting, reordering, suppressing, or hiding and unhiding them as necessary. While there is no specific default layer for welding, you can set a default layer for all welding features (light and solid) by setting the configuration option def_layer to layer_weld_feat , where layername is the name you assign the layer. For example: def_layer layer_weld_feat allwelds Weld features you create after setting this option are automatically added to this default layer. You can customize your welding layers, and how they display, by clicking Show > Layer Tree from the Model Tree.

Creating a Layer for Light Welds Only You can create a layer for light welds only from the Rule Editor dialog box. Set both the rules described below: Look for = Feature

Look for = Feature

Look by = Feature

Look by = Feature

Attributes = Type

Attributes = Type

For more information on rules in layers, see Fundamentals Help.

Displaying Welds

About Displaying Welds You can control the display of welding features in the graphics window, the Model tree, the Layer Tree, and in other applications. When working in Welding, you can make various selections to modify how and when weld features appear.

Displaying Features in the Model Tree Features, by default, are not visible in the model tree for an Assembly. You must select Features from the Model Tree Items dialog box (Settings > Model Tree and select Features). The model tree expands to include all features in the assembly, including welding features.

Displaying Weld Features in the Layer Tree Set the configuration option def_layers to layer_weld_feat to see weld features in the layer tree. All weld features are automatically included in the layer.

Hiding and Unhiding Weld Features You can hide weld features by right-clicking on a weld feature and selecting Hide. This removes the weld display in the graphics window. You can also hide the layer containing weld features so all weld features are hidden.

Changing the Default Weld Color There is a default color for all welds or you can set the color for all welding features using the configuration option weld_color. All welds created after you set this configuration will conform to the color you defined. You can also set colors for individual or multiple welds in your assembly. The new color is also visible in other applications, such as the Standard application.

Using Welding Icons Use to quickly access the WELD DEFINITION dialog box. If you do not see this button after starting the Welding application, you can take steps to position it. Unique icons identify welding features in the model tree. Some are listed below:

Welding Rods

About Welding Rods A welding rod, identified in the Model Tree by , provides the welding material necessary to create a weld bead. A welding rod has a circular cross-section and attributes, such as density, diameter, and length, which you pre-define. Within a welding assembly, each welding rod is defined by its name and parameters. Rod parameters are stored with the model. However, you can use and reuse welding rods in any of your welding assemblies by storing the rod parameters in a .rod file in your working directory. You define and work with welding rods almost exclusively in the WELDING RODS dialog box. First define (or retrieve) rods for the assembly and then assign a selected rod to a weld. You can assign the same welding rod to multiple welds. From a weld feature, you can change a rod assignment from the shortcut menu or edit the weld feature definition to add or change a rod. When you delete a rod that was assigned to a weld, you also need to delete the weld that uses that rod. To avoid having to delete the weld, first unassign the rod and then delete it.

To Define and Edit Welding Rods You define and edit welding rods using the WELDING RODS dialog box. 1. Click Tools > Weld > Rod. The WELDING RODS dialog box opens. If you already defined one or more rods, the rod names are listed in the Rod List and the default rod appears under Rod Parameters.

Welding Parameters

About Welding Parameters Welding parameters automate routine tasks to help streamline your welding design. You can predefine some common feature geometry to ensure design consistency and to save time. Within a welding assembly, each welding parameter is defined by its name and its type of parameter. Welding parameters are stored with the model, however, you can use and reuse welding parameters in any of your welding assemblies by storing the parameters in a .wpr file in your working directory. You can divide welding parameters into the following categories: •

General—Predefines geometry and establish general welding feature behavior in your assemblies.

•

Report—Predefines and establishes welding data for your welding reports.

•

Rod—Creates and controls the behavior of welding rods in your welding assemblies.

You can further customize your welding assemblies by expanding the parameters contained in the categories above by creating optional and user defined parameters.

Controlling a Weld Cross-Section Parameter Using Relations

22

Pro/WELDING

If you want the X_SECTION_AREA parameter to update whenever geometry changes, you can specify a relation that causes this parameter to be recalculated automatically. Two types of parameters can be used in a relation that you specify for the X_SECTION_AREA parameter: •

Model dimensions or any dimensions of an existing weld (such as, leg size) in their symbolic form (such as, d32).

•

Measurement parameters.

When you access the Welding Parameters Info window, the relation that you entered for the X_SECTION_AREA parameter is listed in the table. Values of the measurement parameters can be viewed in the Model Info window.

Method 1: Using the Evaluate Feature 1. Create a weld and specify the initial value for the X_SECTION_AREA parameter. 2. Create an assembly surface feature using the Flat option with the profile of the surface corresponding to the cross-section of the weld. Creating a Surface Based on the Weld’s Cross-Section

` 3. Create an assembly Evaluate feature, measuring the area of this cross-sectional quilt. Specify the name of the Evaluate feature (such as, X_SECTION_AREA). 4. Create an assembly relation which relates the measurement of the surface feature and the X_SECTION_AREA parameter of the weld. (Obtain the internal ID of the weld using Info/Feat Info.) Enter the following relation: X_SECTION_AREA:fid_weld_id = X_SECTION_AREA:fid_evalfeat_id where: weld_id - is the internal feature ID of the weld. evalfeat_id - is the internal ID or the name of the Evaluate feature. 5. Regenerate the model. The system updates the X_SECTION_AREA parameter of the weld; the volume of the weld updates accordingly. 6. If desired, you can put the flat surface on a layer and blank this layer.

Method 2: Using the CALC_X_SECTION_AREA Parameter 1. When defining a weld, define the X-Section plane in the WELD DEFINITION dialog box. This creates a parameter CALC_X_SECTION_AREA. 23

Pro/WELDING Help Topic Collection

2. Create a relation X_SECTION_AREA=CALC_X_SECTION_AREA. When the system solves this relation, it gives you the updated values for the cross-section area.

Tip: Entering Information in the Welding Parameters Table To set up a relation between a welding parameter and measurements of some geometric elements, you enter the following information in the WELD PARAMETERS dialog box. 1. Enter an equation as a value for the desired parameter. 2. For the measurement parameter used in the relation, enter the following line: parameter_name measure where: parameter_name is the name of the parameter. For example, you could add the following lines to the table in the WELD PARAMETERS dialog box: X_SECTION_AREA

a*b/2*1.2

a

measure

b

measure

Note: The length of a relation is limited to a single line of text and you cannot use conditional statements.

Creating Welding Features

About Creating Welding Features 27

Pro/WELDING Help Topic Collection

You define the following Welding features in the WELD DEFINITION dialog box: Edge Prep (Edge Preparation)—Prepares edges for welding when parts and assemblies require certain strength. Weld—Joins metal parts with pressure or an intermediate filler metal with a high melting point. Notch—Creates a cut that enables your welds to cross assembly components without interruption. You can define one or more Welding features at a time. When defining multiple features, you can create edge preparations, welds, and notches in a sequential order. For Weld and Edge Prep features, you can create a single feature (Single), the same weld on both sides of the metal wall (Symmetrical) or for the weld feature only, separate welds on both sides of the metal wall (Unsymmetrical). Although each Welding feature requires a different set of attributes and parameters, there are some common themes between the three Welding features. You define the welding environment to accurately create the weld in either the factory or field. For example, if you are defining a Weld only: •

Select a rod. A rod provides the welding material necessary to create a weld bead. You can use and reuse welding rods in any of your welding assemblies

•

Select the geometry type for the weld. Both solid and light welding features maintain all the necessary definitions and parameters. You can convert between solid and light features for manufacturing and design purposes

•

Clear or select the Create Family Table Instance check box. Welding features belong to the assembly, not to the part. This option controls how and where edge preparations, welds, and notches interact with the Family Table for your assembly. If you choose to create a family table instance, you can customize the instance name suffix and set the weld visibility to either the generic part or to instances of the part and its assemblies. See Fundamentals Help for information regarding Family Tables.

Creating Curves and Light Welds When creating a weld, you can select a combination of curves and edges (one reference after another) when you use the One By One command. When you are in the Welding application you can insert datum curves and then use a combination of curves or curves and edges to create a Light weld. While you are creating a weld, you can insert datum curves, as you do in the Standard application. The Copy, Paste, Intersect, Project, Wrap, Offset, and Trim tools are also available in Welding, although they are not available while you are defining the weld.

About Welding Geometry Types After deciding the type of Weld or Edge Prep welding feature to create, you must also decide how to create geometry in your design. You can select to create either Solid or Light geometry.

28

Pro/WELDING

Solid—Creates and shows the solid geometry within the design. The Weld or Edge Prep feature contains all the necessary data for manufacture and is represented by solid geometry in the design. 1.Reference for solid edge preparation.

Light—References existing curves or edges but has no geometry of its own. The Weld or Edge Prep feature contains all the necessary data for manufacture, but is represented by the geometry it references (edge, surface). The lack of solid edge preparation geometry can significantly reduce the regeneration and graphic load times for your design. 2.Reference for light edge preparation. Because light welding features geometry maintain all the necessary edge preparation and weld parameters, you can quickly convert Light to Solid (and vice versa) for manufacturing and design purposes. If your are creating a number of welds and edge preparations in your model, consider creating (and keeping) all the welds and edge preparations as light geometry and then converting them to solid as needed for manufacturing. Note: •

The Welding configuration options weld_edge_prep_instance and weld_edge_prep_suffix provide the flexibility to customize instance naming conventions and specify on which models the edge preparation features are located.

•

When using light edge preparations, be sure to note the information for the Welding mass properties calculation (Info > Welding > Mass). The mass for light edge preparation is not calculated automatically. Therefore, without user action, the light edge mass is not considered in Mass calculations.

Preparing Edges

About the Edge Prep Welding Feature Edge preparation consists of removing material along edges of metal surfaces. You must prepare edges for welding when parts and assemblies require certain strength. To achieve full welding penetration, you must cut the edges of the metal. The weld replaces the removed material and makes a complete bridge between the joining parts. The following types of edge preparation are available: 29

Pro/WELDING Help Topic Collection

—One side root opening

—V-groove angle cut

—Bevel-groove angle cut

—V-groove angle cut with root opening

—Both sides root opening

—Bevel-groove angle cut with root opening

Edge preparation is only possible for certain weld types. For example, root opening preparation is available for Square-Groove, V-Groove, Bevel-Groove, U-Groove, JGroove, Flare-V-Groove, and Flare-Bevel-Groove welds. Angle cut preparation is available for V-Groove and Bevel-Groove welds.

Default Values for Edge Preparation The WELD DEFINITION dialog box enables you to declare default values for depth, groove angle, and root opening for weld edge preparation. If a gap exists between two surfaces, the dimension of the gap is considered in the equation when you specify root and angle cut measurements. Examples of Depth, Groove Angle, and Root Opening 1 Groove Angle

Creating Welds

About the Weld Feature A weld joins metals by applying heat or a filler metal with a high melting point, or both. In Welding you create welds from parts opened in assembly mode. Welds are created in a top-level assembly as an assembly feature. Welds and feature geometry are represented as quilts with a high level of complexity. Consider the following about the weld feature: •

A weld feature does not change geometry of welded components. Before you proceed to welding, make sure components to be welded have appropriate profiles.

•

Adding a weld does not merge referenced components. When you retrieve a component that was welded in an assembly, its geometry remains the same.

32

Pro/WELDING •

Welds are parametrically defined features. They are associative with the referenced geometry and can be manipulated as other standard Pro/ENGINEER features.

•

Weld faces are represented in the assembly as quilts. A quilt represents a patchwork of connected nonsolid surfaces and may consist of a single surface or a collection of surfaces.

The following weld types are available: —Bevel-Groove or Butt

—Fillet

—Square-Groove or Butt

—U-Groove or Butt

—V-Groove or Butt

—Flare-V-Groove or Butt —Flare-BevelGroove or Butt

—J-Groove or Butt

—Spot

—Plug —Slot

Weld Identification Each weld feature maintains a feature ID, a weld sequence ID, a welding rod, welding parameters, weld type, and geometric references. Weld Identification Format # :Type_of_weld, Rod: Rod_name

Where: #— The sequence ID of the weld. Type_of_weld—The type of weld (such as, "Fillet Weld"). Rod_name—The name of a rod (such as, "Steel_001").

Example: 1:Fillet Weld, Rod: Rod1

About Welding References There are two major steps in the creation of a Weld feature: 1. Define the weld. 2. Specify the weld location. You define a weld from the WELD DEFINITION dialog box by selecting the weld feature type (Fillet, Square-Groove, V-Groove etc.), the environment for the weld feature type (Solid, Light, Intermittent. etc, ) and by adding parameters. Next, you specify the weld location by referencing weld component geometry, using commands from the REF OPTIONS and CHAIN menus. Commands available on these menus during weld creation depend on the weld type you are creating.

Spot Welds

About Spot Welds A spot weld is a joint (or weld) between two overlapping pieces of material. Typically, spot welds are used for sheet metal. To create spot welds, you reference datum points. You can select existing datum points or create datum points in the process of routing the weld. There are two methods of creating a spot weld: •

Define multiple locations for spot welds and create multiple welds in one operation.

•

Create a single spot weld and pattern it using the Pattern command.

The following table shows the key dimensions of the spot weld: Weld Type

Example

Spot

Key Dimension P - Penetration/height XA - Cross-section area d1, d2 – Dimensions locating the center of the spot weld R - Radius of the spot weld is calculated as follows: R = √XA/Π

Spot welds display as circular surfaces. The diameter of the circle is calculated by the system based on the value of the X_SECTION_AREA parameter entered by you when defining weld parameters. To modify the size of the spot weld, you need to change the X_SECTION_AREA parameter. You can set up a relation controlling the area of the weld.

Adding Weld Notches

About Adding Weld Notches A weld notch is an opening (cut) that enables your welds to cross assembly components without interruption. Both the standard and user defined notch shapes enable you to automate and standardize the weld notches in your design, ensuring design consistency and saving you time. You can create single weld notches or you can combine weld notches with edge preparation and weld features. You can only combine weld notches and edge preparations if you simultaneously create a weld feature. You can create a weld notch by manually specifying its individual references (dimensions, location, orientation, and intersecting parts) or you can automatically adopt the weld notch references by referencing the weld notch to a solid or lightweight weld. Weld notches are oriented using coordinate systems. The x-and y-planes are used to place the weld notch and the z-axis defines the direction to remove material. This automatic orientation is accurate. There will be cases where this type of orientation does not meet your design need. If you need a custom notch orientation, define an alternative coordinate system and modify the weld notch's orient section. Multiple intersections of one assembly component part by a single weld notch are not allowed. To create multiple intersections on the part create several weld notch features. The first weld notch feature can be created automatically and then you should create the additional notch features with coordinate systems that define their placement and orientation on the component part.

About Converting Welding Geometry Types Because both solid and light edge preparations and welds maintain all the necessary definitions and parameters, you can convert between solid and light welding features for manufacturing and design purposes using one of the methods below: •

From the Weld Conversion dialog box, select and convert multiple Weld and Edge Prep features, along with any dependent features (children) to the opposite geometry type.

•

Select an Edge Prep or Weld feature from the Model Tree and use the shortcut menu command Convert.

•

From the EDGE PREPARATION or <Weld Type> WELD dialog box, select the Element, Geom Type and change the geometry type of the selected feature.

You can convert solid and light edge preparation geometry types from within parts and assemblies. When you are working in an assembly with the Standard application (Application > Standard) and are converting similar weld and edge preparation features (light weld, light edge preparation), you must convert both features simultaneously (solid weld, solid edge preparation). When you are working with a part in the Standard application, you can convert separate types (solid weld, light edge preparation). However, when you enter the Welding application after making the conversion in the Standard application, you receive a warning message suggesting that you manually convert to resolve the discrepancy.

Guidelines for Converting Solid and Light Edge Preparations When converting solid and light edge preparations the guidelines in the following table are helpful: Use Case

Obtaining Welding Information

About Welding Information Welding information provides general data about your welding design features, including the assembly name, weld type, rods, mass properties, and any welding processes assigned. You can obtain the following information: •

Overall attributes of welds

•

Length of welds and welding rods

61

Pro/WELDING Help Topic Collection •

Mass of welds and welding rods

•

Parameters controlling welds

•

Bills of material for welds

It is important to keep your weld information in mind, especially with respect to light edge preparations and your mass properties calculation. While the light edge preparations do not display solid geometry in your design, they can have a significant effect on the design's mass properties measurement. The length and mass of rods is measured using the following criteria: •

Total rod length is the sum of the lengths of the specified rods. Length is computed by summing the lengths of the particular rods used by all the welds in the assembly.

•

Total rod mass is the sum of the mass of the specified rods. Mass is computed by summing the mass of the particular rods used by all the welds in the assembly.

The information produced for general weld information, weld and rod length, weld and rod mass, and bills of material is written to .dat files in your working directory. Information Type

If you select Sel Weld, the Search Tool dialog box opens. If you select Sel Rod, the ROD NAMES menu appears. b. For Sel Weld, search and select the weld for which you want length or mass information or click Close to close the Search Tool dialog box and select the weld on the Model Tree, or from the graphics window. On the Select menu, click OK. The INFORMATION WINDOW containing the current weld length or mass information opens. c. For Sel Rod, click the check box for which you want information and click Done Sel. The INFORMATION WINDOW opens and contains the length or mass information for the selected rod. Note: Total rod mass is the sum of the mass of the specified rods. Mass is computed by summing the mass of the particular rod used by all the welds in the assembly. Total rod length is the sum of the lengths of the specified rods. Length is computed by summing the lengths of the particular rod used by all the welds in the assembly. 4. If you select BOM, the INFORMATION WINDOW containing BOM (bill of material) information for the welds in the model opens. Note: You can also get information about welding rods, processes, and parameters from the Info menus in the WELDING RODS, WELDING PROCESSES and WELD PARAMETERS dialog boxes. Click Tools > Welding.

Finite Element Analysis of Welded Assemblies (FEA) You can perform a Finite Element Analysis (FEA) of an assembly with weld joints using the same techniques as with other assemblies. A variety of FEA elements can be used to model weld elements, as for example, bar elements, shell elements, and contacts.

Detailing Welding Assemblies

About Welding Symbols in Drawings The standard Pro/ENGINEER welding symbol libraries provide general ANSI and ISO welding symbols. The library symbols are the default symbols. You can easily customize and create new welding symbols to accommodate any symbol preferences. When Pro/ENGINEER places welding symbols in your drawing it only recognizes welding symbol names stored in the standard Pro/ENGINEER welding symbols libraries. If you create a new welding symbol, you must use it to replace an existing symbol in the welding symbols library. As a general rule, it is advisable to redefine an existing weld symbol. As you customize your welding symbol you can do any or all of the following: •

Add as many copies of variable texts as you want.

•

Change the default values of variable texts.

•

Add and delete as many notes and entities as you want and place new ones in any group (or in no group at all).

•

Redefine the cosmetics of existing notes and entities.

•

Move the origin position for Left Leader and Right Leader or add other leader types.

•

Add parameters to the symbol definition.

You can label your welding features with either ANSI or ISO weld symbol standards. The weld_symbol_standard configuration option in the Detail module enables you to set the symbol support for your drawings. The following weld symbols are supported in ISO: •

Non-grooved—Fillet, plug, slot, and spot

•

Grooved—Square, bevel, v, u, and j Note: For bevel and v-symbols, if root_open is more than zero, the "steep" version of the symbol is used. If prep_depth is less than material thickness, the broad version is used.

To Display Welding Symbols for Existing Welds in a Drawing With your welding drawing open: 1. Click View > Show and Erase. The Show/Erase dialog box opens. 2. Under TYPE click

64

.

Pro/WELDING

3. Under Show By specify where to display the symbols: o

Feature—Shows a symbol for a selected weld feature.

o

Feature and View—Shows a symbol for a selected weld in a selected view.

o

Part—Shows all symbols in a selected component.

o

Part and View—Shows all symbols in a selected view of a selected component.

o

View—Shows all symbols in a selected view.

o

Show All—Shows all the symbols in the drawing. Each welding symbol is displayed only once.

4. Use the Options and Preview tabs to define when and what symbols will display. After you have set the criteria for your welding symbol display, the symbols appear in your drawing.

To Redefine a Weld Symbol Note: Before you start, you must first specify the user’s symbol root directory, because Pro/ENGINEER will only let you save the redefined weld symbols in or below it. Later, you can copy the redefined symbols over the old ones in the system symbols libraries. With your welding drawing open: 1. To place an existing symbol palette in your drawing click Insert > Drawing Symbol > Symbol Instance Palette. The Symbol Palette dialog box opens. a. Select a symbol from the dialog box. b. Place the symbol in your drawing. c. Repeat as necessary and click Close. 2. To create or redefine an existing weld symbol, click Insert > Drawing Symbol > Custom. The Custom Drawing Symbol dialog box opens. a. Define or redefine the symbol. b. Repeat as necessary and click OK.

Restrictions for Redefining a Weld Symbol When you are redefining weld symbols, the following restrictions apply: •

All of the groups that existed in the original definition must remain in the new definition. You cannot add new groups or change the names of existing ones.

•

If you add new variable text or change the name of an existing piece of variable text, the new name must be the same as that of an existing variable text in the original.

•

The height type of the symbol instance must be the same in the new symbol as it was in the original.

Pro/WELDING Help Topic Collection •

The Left Leader and Right Leader placement types must both exist in the new weld symbol.

To Replace a Symbol in a System Weld Symbol Library The system weld-symbol libraries are located in the installation directory path /symbols/library_syms/weldsymlib. To replace a standard symbol with one that you have redefined, ask your system administrator to do the following: 1. Move the original (system-supplied) symbol from the system weld library to another directory or rename it. 2. Copy the new user-redefined symbol into the system weld library.

To Store a Redefined Weld Symbol You do not have to store a symbol on disk to use it in your current drawing. However, you must store the symbol on disk for the symbol to be available for other drawings or other users. With your welding drawing open: 1. Click Format > Symbol Gallery. The SYM GALLERY menu appears. 2. Click Write. The GET SYMBOL menu appears. 3. Click Name. The SYMBOL NAMES menu appears. 4. Click the name of a symbol previously retrieved or VIEW_TEMPLATE_SYMBOL. You are prompted for a directory. 5. Type the name of the destination directory (offset from the symbol root directory) and click

66

. The weld symbol is stored.
