When the Welding tool cannot create a weld over a complex path, you can first create a simplified version of the weld, and then use Edit Weld Geometry to refine the simplified version. This is a mode that allows you to edit the weld geometry using other Creo tools like Extrude.

Edit Weld Geometry is available for fillet welds with a solid geometry type. Only single body operations are supported, multi body capabilities are not available.

When you enter Edit Weld Geometry mode and make changes to the weld that add or remove geometry, then when you deactivate this mode, a new set of parameters is created to store the information about the new geometry​. The new parameters are created only if you created a feature in Edit Weld Geometry mode. The parameter sets are based on the selected type of weld, for example, fillet weld.

The name of a new parameter usually is the name of the original parameter, with the suffix _OUTPUT added. For example, if the original parameter name is WELD_LENGTH, then the new parameter name is WELD_LENGTH_OUTPUT.

When you deactivate the Edit Weld Geometry mode, the value in a new parameter might still be the same as the value in the original parameter. It is a best practice to review the new parameters in the Parameters dialog box, and update the new parameter values as needed.

You can easily find the new parameters in the Parameters dialog box by setting the filter to Edit weld geometry.

New geometry and parameters are stored inside the existing Weld feature.

Converting an Edit Weld Geometry feature from solid representation to surface or light representation is possible. However, switching to surface or light representation deletes all the features created in Edit Weld Geometry mode.

If you create a family table instance for a part or an assembly that contains an Edit Weld Geometry feature, add the Edit Weld Geometry feature as a Feature to a family table.

Only solid geometry affects mass properties (volume, mass, cross-sectional area).
