Underwater friction stir welding of Al-Mg alloy: Thermo-mechanical modeling and validation by Talebizadehsardari, Pouyan

“…To better understand the effects of the water environment, the results were compared with conventional friction stir welding (FSW) conditions. Thermal profile and surface heat flux results revealed that lower preheated area (PHA) at the leading edge (LE) decreased the total amount of frictional heat generation in the UFSWed joint. …”
