Pro Welds

You can edit a virtual or Pro weld by right-clicking the Weld GCD (in the Manufacturing Process or Geometric Cost Drivers pane) and selecting Edit Operation. The Welding dialog is displayed in the lower right-hand pane of the Operation Sequence dialog. For more information, see the Weld GCDs section of the aPriori User Guide.

In starting point VPEs, if aPriori is unable to obtain the width of a Pro weld from the values specified in the CAD model, it attempts to estimate the width in one of the following ways:

• Estimate the width from the actual as-modeled surface weld geometry (for "surface-type" welds). Administrators can disable this behavior by setting the site variable deriveProWeldWidthFromGeometry to false.

• Estimates the width based on the weld depth. Administrators can disable this behavior by setting the site variable deriveProWeldWidthFromDepth to false.

If aPriori is unable to obtain the width of a Pro weld from the values specified in the CAD model, and it uses neither of the above estimation methods, the width is set to 0.

aPriori sets to 0 width and depth values that it is unable to obtain or estimate. Welds with 0-valued width or depth have 0 volume and 0 cross-sectional area. In starting point VPEs, such welds fail to cost. To address missing dimension values, users can either update the Creo model parameters in Creo, or override the weld properties in aPriori.

Administrators can direct aPriori to cost 0-cross-sectional-area welds instead of failing them, by setting the cost model variable failWeldsWithZeroCrossSectionArea to false. Note that in this case, many components of cycle time are 0, but overall cycle time is not 0, since it includes components that are independent of weld dimensions.
