立向角焊缝一次成形自动焊接技术

Research on vertical fillet once forming welding technology

研究了立向角焊缝的一次成形自动焊接关键技术,包括:一套使焊点熔池上升速度与焊接小车上行速度匹配协调的自动控制系统;适应角缝焊接并能对焊缝强制冷却成形的特殊水冷滑块;一套能使焊枪和水冷滑块在水平面内进行转角调整的调整机构。借助于气电立焊技术对其创新,实现了立向角焊缝的一次成形自动焊接,填补了此项技术的空白。

This article researched vertical fillet once forming welding technology,which including：a set of automatic control system which matching molten poor＇ rise velocity and the upward travel speed of welding tractor;fits for fillet weld and special water-cooled slide block sharped in forced cooling of weld;a set of reconditioner,which can adjust angle for welding fun and water-cooled slide block at horizontal plane.With the help of electrogas welding technology,the vertical fillet once forming welding technology filled the gap in welding field.
