摘要:
介绍了油气长输管线现场焊接施工的需求，以及激光/GMAW复合焊具有的能显著提高光束能量利用率、改善焊缝成形、降低接头装配精度要求、改善接头力学性能等一系列优点。油气长输管线现场焊接施工时，不论是整个组对接头均采用激光/GMAW复合焊，还是先采用激光/GMAW复合焊接根焊道，随后采用GMAW进行填充焊，两种技术方案均能满足X80和X100高钢级管线钢管焊接接头的性能要求。
Abstract:
This article introduced welding field construction requirements of oil and gas long distance transmission pipeline,as well as advantages of laser/GMAW hybrid welding technology,such as increasing the laser beam efficiency,improving weld figuration,decreasing the requirement of joint assembly precision and improving the mechanical properties of welded joints.During field construction,whether laser/GMAW hybrid welding for whole assembly joints,or laser/GMAW hybrid welding for root pass firstly,then GMAW for filling,both the welding technologies can meet mechanical properties requirements of high grade X80,X100 pipeline steels welding joints.
