Welding symbols

You can insert Welding Symbols into your design, drawing sheet, or 3D markup Closed slide. They can be created with or without geometry in the design window.

Symbols can be made to either the AWS or ISO standard.

AWS follows the specification titled "AWS A2.4:2007 Standard Symbols for Welding, Brazing, and Non-Destructive Examination."
ISO follows "ISO 2553:1992 (E) Welded, Brazed, and Soldered Joints - Symbolic Representation on Drawings - p.193 of ISO Drawings."

SpaceClaim defaults to the AWS standard. You can change this in the Annotation options in the Detailing>General section of SpaceClaim options. The setting is independent of the standard chosen for font.

The basic procedure for creating Welding symbols is to build up the symbol, adding progressively more detail while the UI adapts intelligently based on your choices. There are tooltips available for every possible input value or symbol. Box-selecting the entire symbol will show all possible places to input values. Weld symbols can be created and edited while in the Welding Symbol tool.

The image below shows a blank welding symbol. As you move the cursor over the highlighted areas, tooltips will guide you in building the symbol.

Welding symbols have an Arrow side and an Other side. The Reference line Closed divides the symbol into the Arrow Side and the Other Side. In AWS, the Arrow Side is always on the bottom of the Reference line Closed . In ISO Closed , the Arrow Side is identified by a dotted line as shown in the image below.

To create a Welding Symbol:

Select a Welding Symbol Standard in the Annotation options in the Detailing>General section of SpaceClaim options.
Click the Welding Symbol.
Click to place the arrow
Click to place the Reference Line.
The symbol is now placed and ready to be built.
1. You can add or remove a Jog Point to a Welding Symbol leader while in the Welding Symbol tool. RMB click on the symbol leader to display this option.
2. You can press the ESC key after beginning symbol placement to delete the leader and cancel the tool.
As you move the cursor over the symbol, highlighting will indicate where you can add symbol elements or input values.

Do any of the following in any order to build up the symbol.

Click on either the Arrow Side or the Other side box to display the symbol palette (see images and details in the sections below).

AWS Symbols

ISO Symbols

Click on the Reference line to display the Reference line mini-toolbar (see images and details in the section below).
Reference Line mini-toolbar options

Symbol
Option
Stagger intermittent welds
Weld all around
Field weld
Swap arrow and other sides
Joint with spacer
Show tail even if reference is not used
Add welding reference line
Add welding symbol leader
Click on the Tail text box to enter a specification process or other reference. If there is no reference, the tail will be omitted. You can choose to show the tail regardless of reference by clicking on Show tail even if reference is not used

As you select symbols from the palette and choose options from the mini-toolbars, the available symbols and options will change to present only those that make sense for the current symbol configuration. Tooltips are provided to describe possible symbols and inputs.
Selecting symbols after they are placed will display the symbol mini-toolbar, which contains options to:
- Open the symbol palette and change the symbol
- Add secondary symbols appropriate for the selected symbol. For example, a backing symbol can has the option to add a Removable backing symbol
- Add contour symbols for (left to right): No contour symbol; Flush or flat; Convex; Concave
- If you add a Contour symbol, you can add a Finishing symbol for: No finishing; Chipping; Grinding; Hammering; Machining; Planishing; Rolling; Unspecified

Some notes about Welding Symbols:

Welding symbols can have multiple leaders.
To delete a welding symbol, select the leader and press the Delete key. If there are multiple leaders, you need to delete them all to delete the symbol.
You can CTRl+drag to copy a welding symbol.
You can only input one line of text in the symbol text blocks.
If you need to resize the Reference Line, change the font size to change the size of the Welding Symbol.
Newly inserted symbols are placed in the current active layer.
