摘　　要：采用瞬时液相扩散焊双温工艺对石油连续管CT80进行了焊接,使用氩气保护,铁镍非晶箔作为扩散焊中间层,焊接压力3-4 MPa。分析了接头的显微组织,测试了接头性能。结果表明,双温工艺参数为1210℃加热0.5 min,迅速冷却到1180℃保温4min时,扩散焊焊缝组织均匀,接头强度大于652 MPa。The coiled tubing （CT） was joined by transient liquid-phase two-step heating bonding process using Fe-Niamorphous filler in argon atmosphere under weld pressure of 3-4 MPa. The microstructure and mechanical property of thebonding joint was studied. The results indicate that the joint microstructure is best and the strength is 652MPa when thebonded process is used at 1210℃ heating 0.5min and 1180 ℃ for 4 rain.
