According to the high-speed forming process characteristics of the pre-welding unit of spiral two-step welding production line, in order to meet cutting demands for heavy wall thickness steel pipe, and ensure pre-welding unit production continuously, the improvement design for cutting device was carried out. It added a new differential-speed cutting mechanism and adopted plasma double-torch cutting process. The improved cutting device is with good application result, stable operation, which can fully meet requirements of cutting steel pipe.
