For example, available furnaces may be too small, the weld may be a repair in a structure too large to heat treat or there may be a component in the neighbourhood which would be damaged by the heating.See all results for this questionWhat does post weld heat treatment ( PWHT ) do?The Post Weld Heat Treatment (PWHT) service offered by the JST-Group helps improve the weld microstructure, which in turn reduces the residual stresses that often develops during the welding stage. We are one of the leaders in post-weld and post-heat treatment for steel and metal fabrication, with a team of highly experienced specialists.See all results for this question
