摘　　要：基于有限元预测模型,构建了普通不锈钢低功率激光-双面TIG复合焊,对低功率激光-双面TIG复合焊本身所具有的熔池形貌与循环规律进行了模拟分析,同时对低功率激光-双面TIG复合焊体系进行了实际搭建,并对比分析模拟结果。试验结果显示,实际焊缝形貌与实测温度曲线、模拟温度曲线以及模拟焊接融合线具有良好的吻合度。In this paper, based on finite element predictive model was constructed ordinary stainless steel low-power laser-sided TIG hybrid welding of low-power laser-morphology and circulating bath duplex TIG hybrid welding law itself has carried out a simulation analysis , while the low power laser-sided TIG hybrid welding system was actually built, and comparative analysis of simulation results, test results show that the actual weld morphology and measured temperature curve, analog and analog tern perature curve fusion welding wire has a good fit degrees.
