采用钨极氩弧焊接(TIG)方法,在不同焊接热输入下对2205双相不锈钢3mm薄板进行焊接试验;并对不同热输入的焊缝、热影响区分别进行了金相制备、拉伸试验和冲击试验;根据试验结果对不同热输入时2205双相不锈钢薄板焊接接头金相组织和力学性能进行了分析。为2205双相不锈钢薄板焊接提供参考。
Tungsten arc welding (TIG) method was used to weld 220mm duplex stainless steel 3mm sheet under different welding heat input. Metallographic preparation and tensile test were carried out on the weld and heat affected zone And impact test. According to the test results, the microstructure and mechanical properties of 2205 duplex stainless steel sheet welded joint were analyzed. Provide reference for 2205 duplex stainless steel sheet welding.
