摘要
采用半自动氩弧焊焊接工艺,对大口径(DN>300)双金属复合管进行焊接,包括焊前预处理、根焊、过渡焊、填充焊、盖面焊,解决了双金属复合管仅靠手工焊接施工造成的焊接速度慢、工人劳动强度大及焊接热输出量大而影响不锈钢层耐蚀性等难题。
A Semi - automatic TIG welding process for large diameter（DN 〉 300）bimetal composite pipe for welding,including pretreatment before welding,root welding,soldering transition,filling welding,cosmetic welding,solved the slow speed,high labor intensity of workers and the welding heat output the amount is large and the effects of stainless steel corrosion resistance and other problems of the double metal composite pipe by hand welding.
