摘要
采用激光焊与钨极氩弧焊两种方式对孪生诱导塑性钢的焊接性能进行研究,分析了两种焊接方式对焊接热影响区和焊缝区晶粒状态和力学性能的影响。结果表明,采用激光焊比钨极氩弧焊得到的晶粒要细小,但两种方式都使孪生诱导塑性钢的断后伸长率降低。
The welding property of TWIP steel was studied by laser welding and argon tungsten-arc welding. The effect of welding manner on grain state and mechanical properties of the welding heat affected zone and weld zone were analyzed. The results show that the grain size in welding heat affected zone and weld zone of laser welding is smaller than that of argon tungsten-arc welding. And the percentage elongation after fracture of both are decreased.
