摘要
研究了珠光体钢和奥氏体不锈钢复合管钨极氩弧焊(TIG)接头的性能。采用TIG焊和超低碳奥氏体不锈钢焊丝TGS-309L焊接20/0Cr18Ni9复合管的过渡层焊缝,焊后利用金相显微镜和扫描电子显微镜对焊接接头进行了分析研究。研究结果表明,焊缝成分和金相组织能保证复合管使用过程中的性能要求。
Properties of pearlitic steel and austenitic stainless steel compound pipes TIG welded joint are studied in this paper.TIG welding process with TGS-309L super-low carbon austenitic stainless steel welding wire is used on the transitional layer of the weld of20/0Cr18Ni9compound pipes.After welding,the welded joint is analyzed and researched by metallurgical microscope and scanning electron microscope.It’s proved that the compositions and metallurgical microstructure of the weld can meet the demands for properties in compound pipe service.
