Tack Welds

[WeldGk]

I have always requested tack welding be completed within the parameters of an ASME IX qualified WPS. Product is not pressure-containing (not ASME B31). Is there a statement in ASME IX that requires tacks to be compliant with a qualified WPS?

No, not Section IX. This would be addressed in the construction code, like ASME Section I or VIII. All Section IX does is provide guidance for weld or braze procedure and welder/brazer qualification.
