Study on Weiding Technology of 20 / 0Cr18Ni9 Clad Pipe with Super-thin Inner Liner

超薄复合层20／0Cr18Ni9复合管焊接工艺研究

Welding technology and properties of welded joint of 20 / 0Cr18Ni9 clad pipe with thin stainless steel inner liner were studied .

研究了薄不锈钢内衬20/0Cr18Ni9复合管的焊接工艺和焊接接头性能。

But recently , the quality of stainless steel products is irregularity , and some manufacturers used 0Cr18Ni9 / 304 instead of 0Cr17Ni12Mo3 / 316 and 00Cr17Ni12Mo3 / 316L . It takes incipient fault to the safety of pressure vessels .

近来，由于不锈钢产品质量参差不齐，甚至将0Cr18Ni9/304假冒为0Cr17Ni12Mo3/316、00Cr17Ni12Mo3/316L，给压力容器生产带来安全隐患。

TIG welding process with TGS-309L super-low carbon austenitic stainless steel welding wire is used on the transitional layer of the weld of20 / 0Cr18Ni9 compound pipes . After welding , the welded joint is analyzed and researched by metallurgical microscope and scanning electron microscope .

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。
