Optimization Study of Post-Weld Heat Treatment for 12Cr1MoV Pipe Welded Joint

open access: yesMetals, 2021
In order to clarify the role of different post-weld heat treatment processes in the manufacturing process, welding tests, post-weld heat treatment tests, and finite element analysis (FEA) are carried out for 12C1MoV steel pipes. The simulated temperature

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.

Investigation into the influence of post-weld heat treatment on the microstructure and hardness of Inconel X-750 [PDF]

open access: yesAdvances in Mechanical Engineering, 2015
This work describes a post-weld heat treatment for a precipitation-hardened nickel alloy. Inconel X-750 is a nickel-based superalloy for gas tungsten arc welding processes. The materials were heat-treated in two steps: solution and aging.
