2. Description:
This automatic welding machine for H beam aoppts the AC frequency converter to control speed with the merits of stable and reliable running and quick returning. I t uses the auto- arc tracing and centering device to ensure the welding gun being automatic and correct centering to the target work piece. Meanwhile, it is equipped with the auto weldig flux feeder and recovery system, easy operation and high efficiency.
Working principle of gantry welding machine is as following:
1) One H-beam steel placed on workpiece support frame with 45°,which is suitable for boat welding
2) Gantry welding machine walks on rails at adjusted welding speed
3) Use SAW welding to weld two seam
4) Arc-guide frame automatic seam tracking
5) Flux automatic feed and recovery system
Flux recovery system is composed of flux recovery machine, flux cylinder, flux bucket, flux feeding pipe, flux recovery pipe and so on. They work together to realize automation of flux feeding and recovery process.
Electrical control system is fixed in upright column. While operation panel is on electrical control box’s panel. The electrical control system control movement of trolley, up-down of welding arm, start and stop of SAW welding power, start and stop of flux recovery machine and so on. The movement of trolley is frequency speed adjust controlled, the welding speed can be adjusted according to welding technology requirement.
