Nugget size

SORPAS® shows a zero-nugget size

If SORPAS® shows a zero-nugget size it may be because the workpiece by mistake has been defined as an electrode. Because SORPAS® calculates nugget size between workpieces and not between electrode and workpiece, a zero-nugget size is the result. To solve the zero-nugget size in this case:

  1. Mark the workpiece with the wrong definition. In the “Object type and material” change the definition of the workpiece from electrode to workpiece.

SORPAS® doesn’t show a nugget size

When welding dissimilar materials together, like aluminium and steel, normally, only the aluminium sheet melts and no melting of the steel sheet occurs. In this case, you can show the weld nugget size with two options.

  1. Go to “Preferences”, check the “Nugget Size at Interface” and set the slider at “Larger”
    This shows the final nugget results.
  2. In the “Input Wizard Step 7”, set the “Targeting weld nugget size” at “Max”.
    This makes the reference nugget size from the side with larger melting area. This must be done before “Weld planning”.
