摘要:
双金属复合管的焊接接头结构复杂,焊接难度较大。通过对双金属复合管端面处理工艺和对接焊接工艺分析,提出了端部堆焊工艺较端部封焊工艺易于焊接但不够经济的现状,指出对于薄壁小直径双金属复合管道的焊接宜采用合金焊丝对接焊工艺,而对于厚壁大直径双金属复合管道则宜采用过渡焊方法焊接。另外,还分析了当前的焊接评定标准,强调了制定适宜复合管的焊接工艺评定标准的必要性。
Abstract:
The welded joint structure of bimetal-lined pipe is complex and is difficult to be welded.  Through analysis on pipe end treatment and butt welding procedure for bimetal-lined pipe, it indicated the overlaying was easy to weld but not to be economic comparing with seal welding, it also pointed out that alloy wire butt welding might be used to weld thin wall and small diameter bimetal-lined pipes, while for thick wall and large diameter pipes the buffer layer welding method can be used. Additionally, the existing standards about welding procedure qualification were analyzed in the paper, and the necessity of drafting welding procedure qualification standard about bimetal-lined pipes was emphasized.
