Re: [MW:23063] Clarification on Impact test of WPS and Prduction welds_ASME Sec 8 Div 1

Given combination is not exempted from Impact testing (Fig UCS-66M)

For PTC your designer need to classify (which category?) whether these are as per Fig UW13.2 or covered by U2(g) as angle joints (with α > 30 ° as per UW3)
