This work is devoted to research of hot spots generated by induction heating to prevent hot cracks during laser welding of Al-Mg-Si and Al-Si aluminum alloy samples 2 mm thick. The results of numerical modeling of temperature fields and stress fields formed during the process of induction heating, as well as results of experimental validation of the simulation are shown. 25 Ref., 3 Tables, 10 Figures.
Keywords: laser welding, induction heating, aluminum alloys, modeling, SYSWELD, thermal stresses, hot cracks
