It is used for automatic seam closing and submerged arc welding of circular pipe, taper pipe and polygonal taper pipe.
1. The welding gun is fixed and the workpiece moves in a straight line to realize the function of welding while closing, which greatly improves the working efficiency.
2. The welding seam adjustment function ensures the accurate alignment of the welding gun and the automatic welding.
3. The top seaming device is matched with the side seaming device to close the longitudinal seam of the rolled workpiece; Automatic control of sewing pressure; The joint welding state is reached.
4. The all-in-one welder reclaiming and conveying machine is mainly used for automatic reclaiming, impurity removal and automatic conveying of welding flux during submerged arc welding.
