Re: [MW:23065] Clarification on Impact test of WPS and Prduction welds_ASME Sec 8 Div 1

Consider the Material is Normalised or Quenched & Tempered, it falls under Curve D. According to Table UCS-66, for 60mm Thk, any temperature less than
-17degC requires Impact Testing of both Base Metal & WeldMetal. Hence for Temperature of -46degC, 60 mm thk requires Impact testing.

For Corner Joints, minimum thckness Applies. Please provide the actual thickne

Production Impact Test is required for Weld & HAZ

1. For each welding procedure used for Category A Joint.
2. Different welding procedure used for Category B Joint other than category A.
3. For SAW welding for each position
