Influence of post weld heat treatment for weld joint of P355GH

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 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 ...
