SA516 Gr.70 PWHT
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.

For example sa 516 grade 70 has the highest tensile and yield strength range due to the highest Carbon content(up to0.28%). For higher grade like sa516 gr 70 steel plate, preheating might be needed for metal arc welding process, especialy with thick steel plate.
Preheating, Interpass and Post Weld Heat Treatment
interpass temperature (in multipass welds), and post weld heat treatment (PWHT) is to reduce the risk of cold cracking in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking (see 2.2).

Postweld Heat Treatment Code Exemption Pt 1 TWI
Post weld heat treatment is applied to welded steel assemblies, primarily to reduce the likelihood of brittle fracture. The benefits of PWHT include a significant reduction of tensile residual stresses in the weld joint and, to a lesser extent, tempering of the heat affected zone and the weld metal microstructures.
