This machine is used for box-beam automatic SAW welding. It also can be used for H-beam fillet welding in down hand after changing the arc guiding rack. After completing the box-beam ESW (electro-slag welding), transfer the box-beam to one side of SAW welding machine. And then transfer the beam to another SAW welding machine after completing one seam. The welding arm with submerged arc welding head can move in vertical and horizontal directions to make the welding head aim at the welding seam. On welding arm, there is pneumatic mechanical arc-guiding device to realize the tracing. And the machine can do the automatic SAW welding. There is flux feeding and recovery device for this machine.
