X-ray diffraction was utilized to measure the residual stress of 45 mm UNS N08810 plates after post-weld heat treatment at temperatures of 680℃and 900℃,which showed reductions of 86.9%and 71.6%in the residual stress,respectively.This indicates that post-weld heat treatment can play a significant role in reducing residual stress,while no significant effects on tensile stress and micro-hardness of the welding joint were observed after treatment.
