基于Fluent的GMAW焊接熔滴过渡过程的动态模拟
Dynamics simulation of metal transfer in GMAW based on Fluent software
摘要
Abstract
The dynamic process of pulse metal transfer mode such as one pulse per droplet and two pulse per droplets in CMAW(Cas Metal Arc Welding) is simulated by use of Fluent which is a commercial software used to compute fluid dynamics.Based on the fluid dynamics theory and electromagnetic theory,a dynamic model of metal transfer is developed and drop formation,evolution and detachment are simulated.Meanwhile the welding experiment is carried and the high-speed photography is used to record the real process of metal transfer.The results show that the simulation results are in good agreement with the experimental ones.The metal transfer mode of one pulse per droplet is mainly affected by the welding current.The range of current can be obtained by means of the simulation.So it could be used to guide the welding experiments and the experiments decrease.关键词
