Welding Symbols

This subtopic provides more information about how to define primary welding symbols, complementary symbols and finish symbols to create the welding symbol.

You can add the following welding symbols according to the dedicated standard.

Weld Type

Name AWS ISO JIS
Square butt weld
Singe-V butt weld
Single-bevel butt weld
Single-V butt with broad root face NA NA
Single-bevel butt with broad root face NA NA
Single-U butt weld
Single-J butt weld
Fillet weld
Corner Flange weld NA
Edge Flange weld NA
V Flare weld
HV Flare weld
Spot weld or
Back weld
Steep-flanked single-bevel butt weld NA NA
Steep-flanked single-V weld NA NA
Plug weld
Removable backing strip used NA NA
Permanent backing strip used NA NA
Surfacing weld
Seam weld
Scarf weld NA NA
Stud weld
Edge weld
Melt Thru weld
Consumable
Transparency
Overlay
End to end NA



Complementary Symbols

Name AWS ISO JIS
Weld with flat face
Weld with convex face
Weld with concave face
Fillet weld with smooth blended face NA NA

Finish Symbols

Name AWS ISO JIS
Circular





Multidirectional





Radial





Particulate, non-directional, or protuberant NA



Angular in both directions NA



Parallel to the line representing the surface NA



Perpendicular to the line representing the surface NA



Complementary Indications



 Field weld


Weld-all-around




Weld text side (up or down)




Indent line side (up or down)


Weld tail

Alternative welding staggered display

Miscellaneous Information

  • If you have selected the Use style values to create new objects check box in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Administration tab, the Welding creation dialog box is prefilled with custom style values (as defined in the Standards Editor). In this case, properties in the Object Properties panel and the Tools Palette are not available during the creation of the welding symbol. Otherwise, if you have not selected this option, the Welding creation dialog box is prefilled with the last entered values (if any). In this case, properties in the Object Properties panel and the Tools Palette are active during the creation of the welding symbol.
  • You can reset the current style values in the Welding creation dialog box by clicking Reset.
  • You can close the tail (reference) using a rectangle variable-size frame . For more information about adding frames, see Adding Frames or Sub-frames.
  • At any time, you can modify the welding symbol. To do this, double-click the welding symbol to be modified and enter the modifications in the displayed dialog box.
  • The welding symbol is automatically updated when the drawing standard is switched. For example, from JIS to ISO. During the switch, if a welding symbol is unavailable in the target standard, it is replaced by an underscore.

Associativity to 3D Welds

In Drafting context, Generative View Styles (GVS) enable you to specify whether weld features defined in 3D (in the Weld Design app) are to be represented symbolically in views.

For more information, see Drafting User's Guide: Administration: Setting General Generative View Style Parameters: Generate Parameters.

If you create a view containing a weld symbolic representation using GVS, you can then create a welding symbol associative to the 3D weld specification, by selecting either the side or the top representation of weld seams (even if they are hidden by other geometry). In this case, the Welding Creation dialog box is prefilled with the following information:

  • Weld type (simple or double information)
  • Weld length
  • Weld thickness
  • Weld-all-around symbol that is
Notes:
  • When updating the drawing, if the 3D weld specification cannot be found (if it has been deleted for example), the welding symbol update fails. In this case, the welding symbol content is not modified, and it is displayed using the color specified by the Weldings for which last update failed check box in Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Display section, under Elements Analysis, selecting Activate elements' analysis check box, and clicking Configure. For more information, see Display.
  • You can right-click an associative welding symbol, Isolate, and Query Object Links are available.
  • You can also create dimensions on weld representations by selecting their profile. However, such dimensions are not associative and cannot drive the 3D. The image below shows a dimension created on the side representation of the weld seam.
