Post weld heat treatment for high strength steel welded connections [PDF]
Journal of Constructional Steel Research, 2016 Abstract In this study, experiments were conducted to investigate the effect of post-weld heat treatment (PWHT) on the reheated, quenched and tempered (RQT) grade S690 high strength steel welded connections. Firstly, the effect of PWHT on the mechanical properties after welding is investigated. It is found that the loss of both strength and ductility
