摘要
在平原段成熟的自动焊施工工艺方法基础上,针对山区长输管道施工地形复杂,坡道多,弯管用量多的特点,提出了适用于山区长输管道的两种自动焊施工工艺研究方向,一种是开发山区柔性内焊机根焊+外焊机填盖的工艺,柔性内焊机的使用,解决山区热煨弯管及坡道上的内根焊焊接问题,配套需要加长热煨弯管直管段长度及改进坡口机加工热弯坡口的能力;另一种是氩弧自动焊根焊+外焊机填盖的工艺,自动氩弧焊根焊技术解决自动焊根焊单面焊双面成型的问题,设备的轻便化,可适用于各种山区地形的焊接施工。两种工艺方式均采用窄间隙的坡口设计,提高了山区自动焊施工的效率和质量。同时,针对这两种工艺,提出了设备、管材和热煨弯管优化制造的要求。
On the basis of the mature automatic welding construction technology in the plain section,and in view of the characteristics of the mountainous long-distance pipeline construction,such as complex terrain,many ramps,and a large amount of elbows,this paper puts forward two research directions of automatic welding construction technology suitable for mountainous long-distance pipeline.One is to develop the process of flexible internal welding+external welding machine covering,and the other is the process of argon arc automatic root welding+external welding machine covering.At the same time,the requirements for the optimal manufacturing of equipment,pipes and hot bends are put forward.
