The strip material is introduced into the welding pipe machine through the feeding machine, and is extruded into shape through rollers. Then, the strip material is welded and rounded using a mixture of arc welding and gas protection. The required length of the pipe material is output, cut by the cutting mechanism, and then straightened by the straightening machine. Spot welding machines are used for spot welding connections between strip heads. This type of pipe making machine is a comprehensive complete set of equipment that continuously welds the strip material into pipes, and aligns and straightens them.
