通过对409L铁素体不锈钢手工钨极氩弧焊焊接试验分析,确定409L材料焊接性能和焊接工艺方案。试验结果表明,409L适用于手工钨极氩弧焊焊接,且在满足设计条件下,409L材料可替代部分产品中奥氏体不锈钢材料,从而降低产品成本。
409L ferritic stainless steel by manual TIG welding test analysis to determine the 409L material welding performance and welding process options. The test results show that the 409L is suitable for manual TIG welding and 409L material can replace part of the austenitic stainless steel material to meet the design conditions, thereby reducing product costs.
