摘要

The purpose of this paper is to simulate the residual field of laser brazing by FEM of ANSYS. The 2-D coupledfield element is elected to create finite element model. The brazing experiments have been done by means of 45steel whichis the matrix and Ni-Cr solder and the residual stress of the diamond wheel has been measured by Raman method. Theresults of measure show that the maximum stress value is less strength of diamond. The residual stress distribution isbasically identical between the results of simulation and experiment. According to this paper, it is possible to decrease thecosts of study by selecting reasonable processing parameters on laser brazing.
