    Feb 08, 2005 · The criteria I have determined for PWHT of SA516 Gr.70 material is that it is essential for welds greater then 1 1/2" (nominal thickkness) or 1/2" (nominal) for lethal service. There are other dependants and exceptions identified in UCS-56 which references UW-40 for the definition of 'nominal weld thickness' Thanks again.See more results
