摘要
介绍了直缝钢管焊接生产对预焊的要求及预焊设备与工艺。该设备主要由拘束合缝装置、焊接操作机、焊接系统、电控与激光跟踪系统构成。焊接采用粗丝MAG高速焊工艺 ,电控采用 profibus -dp现场总线构成的分布式控制系统 ,焊缝跟踪及错边检测采用激光闭环跟踪系统。
This paper introduces the tack welding requirement and the tack welding equipment & procedure in the production of straight steel pipe. This equipment includes pipe constraint equipment, welding operator, welding system, electric controller and laser tracking system. The high speed welding technology of large-sized wire MAG is used. The DCS (distributed control system) consisted of profibus-dp is used as electric control system. Laser close loop track system is used for weld tracking and mismatch detect. The equipment and the procedure mentioned are already utilized in the actual production.
