提高螺旋焊管焊道外观质量的工艺措施

Process Measures of Improving Visual Quality of Weld Seam

分析了影响螺旋焊管焊道外观质量的因素,详细介绍了在忠武线、双兰线等长输管线的螺旋焊管生产过程中,为改善外焊道的外观质量所采取的工艺技术措施,如焊接工艺参数的优化设计、焊丝形位参数的调整、焊剂流量的合理控制以及如何选择工艺性能良好的焊剂和如何控制符合焊接要求的成型缝等,以满足管线钢管外防腐对焊道外观质量的要求。

It analyzes the factors of infecting visual quality of weld seam on spiral welded pipe and introduces the process technical measure taken by improving visual quality of outside welded seam,such as optimizing design of welding process parameter,adjustment of welding wire position,rational control the flow of welding flux and how to select flux which has good process and how to control forming seam which can meet requirement of welding,etc..to meet the visual quality requirement of welded seam to outside coating pipeline during production of spiral welded pipe for long distance pipeline as Zhongwu pipeline,Shuanglan pipeline,etc..
