Effect of induction heating to prevent hot cracking during laser welding of aluminum alloys

The work is devoted to research of influence of the process of induction heating plates on the prevention of hot cracks in laser butt welding. Plates were used, which were made from aluminum alloys 6082Т6 and 5754Н22 with thickness of 2 mm. The article shows the results of numerical modeling of temperature fields and stress fields formed during the process of induction heating. The results of experimental validation of the simulation were demonstrated.
