Welding processes (except Ultrasonic Welding) are included in the current routing only if the current assembly contains welds. In many cases you must manually create virtual welds—see Assembly Welds. This applies to eight welding processes:

Each process supports a single welding operation. The characteristics of each weld GCD determine which welds are handled by which process’s operation—see Welding Operation Feasibility.

For the following processes, you must manually assign the corresponding welding operation to each weld that requires it:

In the Manufacturing Process pane or Geometric Cost Drivers pane, right-click the GCD to which you want to assign the operation, and select Edit Operation. Also note that the Weld GCD’s Production Mechanism field must be set to Robotic for either Laser Welding or Electron Beam operations to cost successfully.

You must manually assign Weld Prep and/or Weld Cleanup operations to each weld that requires them. Weld Prep supports the following operations:

Weld Clean Up supports the Grinding operation.

Ultrasonic Welding applies only to assemblies whose primary process group is Assembly Plastic Molding. You must manually assign the Ultrasonic Welding operation to each weld that requires it. In the Manufacturing Process pane or Geometric Cost Drivers pane, right-click the GCD to which you want to assign the operation, and select Edit Operation.

Ultrasonic Welding is preceded by Pick and Place and optionally preceded by one or more of the following:
