Abstract

The article presents the results of research concerning laser lap welding of similar and dissimilar joints. Research was performed using two commonly used materials: austenitic stainless steel in grade 316L and structural ferritic-perlitic S355J2 steel. Developed joints obtained only partial penetration of the down material. Welding parameters were estimated based on numerical simulation using Simufact Welding software. Metallographic macro and microstructure were part of solution. High convergence of numerical simulation to experiments were shown. Results of calculation of maximum stresses and equivalent plastic deformations demonstrate advantages of welding dissimilar joints using stainless steel.
