Numerical Simulation of Temperature Field of Laser Welding Stainless Steel
Abstract：A model was established to evaluates the three-dimensional transient temperature field for laser welding stainless steel by using the finite element method.The thermo-physical properties and latent heat established as the functions of temperature,the surface convective heat transfer,and the radiant heat transfer were taken into consideration.The temperature yield of laser welding was analyzed by SYSWELD software.The results showed that temperature rises rapidly at the starting and ending of welding,and the temperature changes at the middle of section.There is unlimited temperature gradient in the direction of welding and vertical welding.Heat stress is caused by temperature gradient,existence of heat stress is main reason that cracks is created during welding.
