摘　　要：球罐脉冲MAG全位置自动焊具有绿色环保、高效节能等优点,与焊条电弧焊相比,其焊接工艺参数可控,焊接变形量小,更有利于保证球罐的焊接质量,但需解决曲面爬行轨道、焊接小车、机头摆动机构、控制系统、配套的金属粉型焊丝及焊接工艺等诸多技术难题。针对量大面广的Q370R钢制大型球罐,通过对球罐脉冲MAG全位置自动焊接系统中多项子系统的攻关试验研究,实现了自动焊焊接装备在球罐上全方位平稳运行,且价格低廉,研制的金属粉芯焊丝质量稳定,适于Q370R钢制球罐全位置焊接,焊缝金属力学性能较佳,球罐自动焊焊缝成形美观,完全替代了原始的焊条电弧焊,应用前景广阔。Spherical tanks all-position automatic pulse MAG welding has the advantages of high efficiency and energy saving,green environmental protection.Compared with shielded metal arc welding,the welding process parameters can be controlled,the welding deformation is small and the welding quality is easy to be ensured. But many technical problems need to be solved,such as curved surface crawling track,welding trolley,head swinging mechanism,control system,matching metal powder welding process and so on.Through the research on a number of subsystems in the all-position automatic pulse MAG welding system,automatic welding equipment in spherical tank on the full range of stable operation is realized,and the price is very low.The quality of metal powder wire is stable,the mechanical properties of weld metal is good,automatic welding seam molding is very beautiful.The metal powder wire is suitable for Q370 R steel spherical tank for all-position welding,has broad application prospects,the original shielded metal arc welding is completely replaced.
