摘要
依据有关焊接熔池形状和温度场的理论研究成果,确定了双丝直缝埋弧焊中焊丝的空间布置,其特点是两丝中心间距12～15mm,干伸长为25～30mm,两丝有一定的倾角.实践证明,焊接过程中保持合理的焊丝空间布置能获得优良的焊缝质量.
Based on the result of the theoretic research on welding pool shape and temperature field,the spatial distribution of the welding wires in the twin-wire straight SAW process is determined,featuring12~15mm centers of the two wires,25~30mm stem extension and a specific inclination between the wires.Relevant operation shows that maintaining the proper spatial arrangement of the welding wires during operation will ensure satisfactory weld seam quality.
