The traditional equipment is mainly composed of a fixed pressing device, a cutting device and a welding device. Its working process is as follows: after the steel coil is fed into the pressing device through the feeding channel and fixed, the cutting device completes the cutting along a straight line or a simple curve path, and then the welding device butt-welds the cut steel coil.
