Numerical studies of post weld heat treatment on residual stresses in welded impeller
International Journal of Pressure Vessels and Piping, 2017Abstract The temperature filed was simulated by use of the established moving heat source model of TIG welded impeller. The obtained computational temperature can be treated as thermal load for the computation of the residual stress near weld. The comparison with experimental data in published literature can validate the proposed models.

Stress Effect on Post-Weld Heat Treatment Embrittlement
1990Post-weld heat treatment (PWHT) is carried out to improve fracture toughness and to remove residual stress in the heat-affected zone (HAZ). There are some problems, such as a toughness decrease and stress-relief cracking (SRC) in the coarse-grained HAZ subject to the effect of the tempering treatment. Therefore, in this paper, the effect of the heating
