User-Defined Parametric Weld Symbols

Detailed Drawings > Annotating the Drawing > Working with Symbols > Defining Symbols > Parametric Weld Symbols > User-Defined Parametric Weld Symbols

You can replace the Creo Parametric-supplied library of system weld symbols with user-defined ones. After you define the symbols, the system uses them for automatic weld annotation. By customizing your weld symbols in advance, you can increase your flexibility and productivity throughout the processes of creating and modifying drawings.

Before performing this procedure, you should copy the system-supplied welding symbol library to a backup directory.

However, when creating user-defined weld symbols, the following restrictions apply:

• All of the groups that existed in the original definition must remain in the new definition, and you cannot add new ones 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 the existing variable text in the original.

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

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

ISO Welding Symbols

This section presents examples of symbols that enable you to create welding, brazing, and examination symbols in a drawing according to the ISO standard. To help you create symbol instances, it provides the following information for each symbol:

• The symbol name

• An example of an instance created from this symbol and the associated menu picks

• Listings of groups and subgroups in menu format reflecting a tree symbol definition structure

You can also refer to Glossary of Menu Picks below for an explanation of menu selections for welding symbols.

Welding Symbols Library

The Welding Symbols Library, available with Detailed Drawings, provides a collection of symbols based on the standards of ISO-2553-1984. Using this library, you can create a variety of welding, brazing, and examination symbols in a drawing.

To retrieve a symbol from the Welding Symbol Library, choose System Syms from the Select File menu to access the Creo Parametric symbols area.

Glossary of Menu Picks

This glossary describes terms that are unique to the ISO Welding Symbol Library and identifies information you are prompted to enter. Menu pick names track the ISO Welding Symbol Library to the fullest extent possible.

In the ISO Welding Symbol Library, two lines form the reference line, one solid and one dashed. Weld symbols attached to the solid line are "arrow-side." Weld symbols attached to the dashed line are "other-side." The dashed line is only omitted for symmetrical welds. When creating a welding symbol, you first select whether the weld is arrow side, other-side, or symmetrical. If you choose ARROW_SIDE or OTHER_SIDE, the system prompts you to create the weld symbol above or beneath the reference line. It then places the dashed line appropriately in the symbol depending on whether it is arrow-side or other-side.

ISO Weld Characteristics Menu Selections
MENU PICK	OPTION	DESCRIPTION
ABOVE_REF		Creates the weld symbol above the solid reference line.
AS_ABOVE_ REF		Indicates (for combination welding symbols only) whether the arrow-side welding symbol is placed above or beneath the reference line.
BENEATH_REF		Creates the weld symbol beneath the solid reference line.
BUTT_SIZE		Refers to the final size of the weld, depending on the symbol type (arrow-side, other-side, symmetrical, or staggered). It might have the suffix "AS" (arrow-side) or "OS" (other-side) to indicate the appropriate weld side.
CONTOUR	SMOOTH_BLEND	Describes the final shape of the weld. This choice indicates that the toes of the weld are blended smoothly.
FINISH		In the ANSI standard, this specifies the method of finishing. In the ISO standard, the system adds a machine finish surface texture symbol above the contour symbol.
FILLET_SIZE		Refers to the final size of the weld, depending on the symbol type (arrow-side, other-side, symmetrical, or staggered). It might have the suffix "AS" (arrow-side) or "OS" (other-side) to indicate the appropriate weld side.
FIL_SIZE		Refers to the final size of the weld, depending on the symbol type (arrow-side, other-side, symmetrical, or staggered). It might have the suffix "AS" (arrow-side) or "OS" (other-side) to indicate the appropriate weld side.
HOLE_DIA		Refers to the diameter of a plug weld.
OS_ABOVE_ REF		Indicates (for combination welding symbols only) whether the other-side welding symbol is placed above or beneath the reference line.
PROJECT_DIA		Refers to the diameter of a projection weld.
SEAM_WIDTH		Refers to the width of a seam weld.
SPOT_DIA		Refers to the diameter of a spot or fusion weld.
STYLE	CONTINOUS INTERMITTENT	Refers to the longitudinal dimension of a weld. Two choices are available: Weld joint continuously for the specified length. Creates weld beads of specified length, distance between adjacent weld elements, and specific number of beads.
SYMMETRICAL		Refers to a welding symbol for creating identical welds on both arrow-side and other- side.
TAIL	REFERENCE WELD_PROCESS	Creates a tail on the opposite end of the welding symbol from the leader attachment. Provides two choices: Enters reference text or note. Specifies a welding process.
WELD_SIZE		Refers to the final size of the weld, depending on the symbol type (arrow-side, other-side, symmetrical, or staggered). It might have the suffix "AS" (arrow-side) or "OS" (other-side) to indicate the appropriate weld side.
WELD_TYPE		For combination welding symbols, indicates the type of weld being created and whether it is created arrow-side or other-side (e.g., FILLET_AS).
