Description

Torch mobile automatic welding truck

The present invention relates to a torch movable automatic welding running truck, and more particularly, to a torch movable automatic welding running truck which enables to weld a welding part accurately while traveling stably along a rail.

The welding travel truck, which mounts the welding torch on the self-propelled bogie and automatically performs welding, should be able to maintain the correct welding position while the welding torch responds to the bending of the material to be welded when traveling automatically. If the material to be welded is not appropriate to correspond to this, it moves only along the set straight path, there is a defect that can not be welded to the correct position when welding the bent portion of the material to be welded.

In addition, the conventional welding running cart has a problem that the position adjusting device of the welding torch is complicated and inconvenient to use.

The present invention has been devised to solve the conventional problems as described above, so that when the welding target material is bent, the welding traveling cart can stably run while responding to the bending of the material to secure the correct welding position of the welding torch. In addition, it is to provide a torch moving type automatic welding traveling cart which can easily adjust the position of the welding torch by simplifying the vertical and horizontal positioning mechanisms of the welding torch.
