Heat-induced effects and cracking susceptibility in gas tungsten arc welding of Inconel 939 superalloy using Inconel 625 filler metal
This study examines the effect of heat input on crack formation in the heat-affected zone (HAZ) during gas tungsten arc welding (GTAW) repair of Inconel 939 superalloy. The workpiece, which had been in service for 100,000 h before requiring repair, underwent pre-welding heat treatment to enhance wel...
