摘要:
详细介绍了双丝螺旋埋弧焊各种工艺参数的优化与选择，提出：采用直流+交流的焊接方式匹配；钢带边缘铣成不对称X形坡口；内焊偏心距只能控制在0～30mm，外焊偏心距稍大于内焊偏心距；内外焊丝间距一样；内外焊焊丝倾角基本一样，前丝为3°～6°，后丝为8°～13°；内外焊焊丝伸长量一样。对双丝焊的内、外焊电流和电压的选配原则作了着重说明。并指出了提高双丝焊质量的控制要点。
Abstract:
This article introduces optimization and selection of each process parameter for spiral submerged arc welding with double wires in detail and proposes to adopting matched direct current plus alternative current welding method,to milling strip edges with dissymmetry X-bevel,to controlling eccentricity distance of inside welding only within 0～30mm and eccentricity distance of outside welding slightly larger than that of inside welding as well as keeping same distance between welding wires for outside and inside welding and same angle of welding for outside and inside welding,and angle of front wire is 3°～6°and angle of back wire is 8°～13°,same elongation of welding wire for outside and inside welding. It also emphasizes selection and matching principle of inside and outside welding current and voltage to double wires and puts forward to control points of improving quality of double wires welding.
