Stress Relief Cracking (SRC) in low alloy steels was the core focus for this work. Stress relief cracking is an ongoing concern for thick-walled creep resistant steel welds during PWHT when high restraint and high residual stresses are present after welding. While much is alread…

Transient temperature distribution during a Gas Metal Arc (GMA) welding process and cooling of weldment will have significant effects on the microstructure, mechanical and physical properties, and residual stress distribution in the weldment. As part of an integrated effort to m…

Laser technologies have made distinguished contributions to modern industry. These have typically been realised through the important role played by lasers in the advancement of manufacturing technology in many areas such as welding, which has become an important joining techniq…

Laser welding has firmly entrenched itself as an attractive manufacturing process technology in the industry. Despite its role of a viable manufacturing process, its overall efficiency is not significantly higher than other joining processes, in particular resistance welding. It…
