In this paper, for the first time, simulation of of joining stainless steel to low carbon steel was carried out. For this purpose, at first, thermal analysis was carried out by finite element method and of temperature profile and the dimensions of the melting area was gained as results. This was followed by mechanical analysis. The thermal analysis results were stored in a mechanical element as history to obtain the thermal conditions of the material. As results of this analysis, the strain of elastic and plastic as well as the amount of residual stress The results show that low carbon steel passes through in , because of higher thermal conductivity. Also, low carbon steel saves more residual stress due to higher yield stress. For validation of simulated model, two plates of 304 stainless steel with similar parameters the simulated model by laser welding. Comparing the results obtained from the experimental model with the simulated model shows a very good agreement. LA eng UL http://mme.modares.ac.ir/article-15-19600-en.html M3 ER -
