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

Influence of Vibratory Stress Relief on Residual Stresses in Bridge Structural Members Weldments
The Baltic Journal of Road and Bridge Engineering, 2011 The welding process can join two similar materials with a bond that has mechanical properties comparable to the original material. Unfortunately, this process induces residual stresses in the weldment, which, if left untreated, can cause distortion of ...

A novel post-weld treatment using nanostructured metallic multilayer for superior fatigue strength
Scientific Reports, 2023 Welded joints exhibit fatigue failure potential from weld geometry and characteristics of the heat affected zone. In order to counteract fatigue, structures and components require larger thicknesses resulting in heavier designs exhausting the finite ...
