摘要
Abstract
Over height weld reinforcement and too small transition angle between weld and base metal will case stress concentration in weld toe,which can lead to fatigue rupture to the pipeline under service condition,and even influence pipeline safety operation,add much more tasks difficulty of steel pipe external coating,and cause weld external coating thickness reduction even to cracking.Aim at these problems,it analyzed the major factors affecting weld reinforcement quality,and the process measures to improve weld profile,such as optimizing design for bevel and welding process parameters and adjustment for the angle and location of welding wire.By implementation of the above measures,it improved the weld profile and obtained satisfactory results in practice production.关键词
