WebbPost weld heat treatment (PWHT) refers to any heat treatment performed after machining/welding to improve the mechanical and chemical properties of the machined surfaces/weldment. Welding induces residual stresses in a structure, which cause distortions in the structure in the long term. Webb4 juni 2024 · The post-weld heat treatment (PWHT) cracking susceptibility of a coarse grain heat-affected zone (CGHAZ) in SA213-T23 (2.25Cr-1.6W steel) that was used for boiler tubes employed in thermal power plants was investigated using a Gleeble thermal cycle simulator. The PWHT cracking susceptibility test was performed at 650 °C, 700 °C, and …
Webb11 aug. 2024 · In this work, a 2-D axisymmetric model has been employed to investigate the distribution and evolution of stress in 9Cr/2.25Cr dissimilar welded rotor undergoing welding and PWHT. The effectiveness of simulation was validated with hole-drilling method (HDM) to measure the stress on the inner and outer surface of welded rotor. WebbA Post Weld Heat Treatment (PWHT) at 580°C +/-10°C for 1hour per 25mm thickness is appropriate.
