Finite Element Modeling of Laser Impact Welding Technology

Abstract

The high-speed process of laser impact welding is examined. Finite element modeling of the laser impact welding technology is carried out using the Euler thermomechanical method, where the pressure in the shock wave is taken as an external effect. With the help of the developed model, the distributions of rapidly changing velocities along the length of the plates, shear stresses, plastic strains, and temperatures during the entire laser impact welding process were determined. It is shown that, during welding of this type, there is no effect of melting the plates.
