Post weld heat treatment (pwht) is a stress reliever designed to lower residual stresses near welds. Most governing codes require local PWHT treatments in order to prevent fatigue cracking in process piping systems. To determine the optimal conditions for local PWHT, a full factorial design with three factors was implemented. Variables investigated included: Temperature PWHT … <\/p>\n
