Influence of post weld heat treatment for weld joint of P355GH [PDF]

open access: yesMATEC Web of Conferences, 2018
From steel designed to work under pressure and exposed to high temperature apart from the good weldability, good mechanical properties are required. The guidelines set by the regulations require post welding heat treatment above 35mm thick.

Influence of Post-Weld Heat Treatment on the Performance of UHSS Joints. [PDF]

open access: yesMaterials (Basel)
Ultra-high strength steel (UHSS) contributes significantly to lightweight design, environmental compatibility and lower fuel consumption. However, it is essential to maintain excellent mechanical properties in terms of structural integrity, strength and ductility after the applied welding process.

Post weld heat treatment for high strength steel welded connections [PDF]

open access: yesJournal 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

Investigation of Post-weld Heat Treatment of Laser Welded Ti6Al4V Materials

open access: yesBitlis Eren Üniversitesi Fen Bilimleri Dergisi, 2023
In this study, the changes in the internal structure and mechanical properties of laser-welded Ti6Al4V material after heat treatment were experimentally investigated. The transformation temperatures of the α and β phase structures of the Ti6Al4V material influenced the heat treatment temperatures.

Influence of Vibratory Stress Relief on Residual Stresses in Bridge Structural Members Weldments

open access: yesThe 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

open access: yesScientific 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 ...
