Features of Finite Element Simulation of Laser Impact Welding of Aluminum with Stainless Steel

The technology of laser impact welding of a thin aluminum plate with a stainless steel plate is discussed. Finite element simulation of the laser impact welding technology was conducted using the ABAQUS package. The results showed that the quality of the weld mainly depends on two parameters: the energy of the laser pulse and the initial distance between the plates. Conditions were established under which parameters of laser impact welding can be used to weld an aluminum plate with a stainless steel plate. The distributions of plastic strains and temperatures along the weld were obtained.
