摘要
建立了改进的双椭球热源模型和熔滴热的复合热源模型,对CO2气体保护焊的温度场及其流场进行了模拟和计算。分析了CO2气体保护焊在跳跃电弧下的温度场和流场的特征,同时得出跳跃电弧下不同焊接电流的CO2气体保护焊熔池的熔深和熔宽。
To establish an improved double ellipsoid heat source model and melt dripping hot composite heat source model,the CO2 gas shielded welding temperature field and flow field is simulated and calculated. Analyze the characteristics of CO2 gas shielded welding temperature field and flow field under the skip arc, at the same time draw the pool depth and width under different welding current with the skip arc.
