Study on Mathematical Model of Temperature Field in the Laser Welding Process

摘要：

From the laser welding aetual process，the welding heat source model of laser welding process WaS establmhed，that lS，SUperpOSltlOn heat source．According to the knowledge of thermodynamics，the establishment of a welding process．the mathematical model of temperature distribution of laser welding process was obtained by laser welding heat source．Finally,the finite element simulation of welding temperature distribution was used．The simulated results were compared with the analytical results of mathematical model of temperature field．it was proved consistent between simulated results and analytical results，at the same time it Call account for the correctness of the mathematical model oftemperature field．
