Hot cracking remains a significant challenge in the fusion welding of high-strength aluminum alloys, particularly AA6061, which is highly susceptible to solidification cracking in the fusion zone (FZ) ...
Welded joints exhibit fatigue failure potential from weld geometry and characteristics of the heat affected zone. In order to counteract fatigue, structures and components require larger thicknesses ...
