Strip steel, also known as steel strip, is within 1300mm in width and its length varies slightly according to the size of each roll.

[0003] During the strip production process, when the length of the front coil is not enough, the tail end of the front coil needs to be welded with the head end of the rear coil to reach the required length. Currently, the head and tail shearing of the front and rear coils is completed by a shearing machine, and the head and tail welding of the front and rear coils is completed by a welding machine.

[0004] With regard to the above-mentioned related technologies, the inventors believe that when a shearing machine is used to shear the tail end of the front roll and the head end of the rear roll, and then a welding machine is used to weld the tail end of the front roll and the head end of the rear roll, during the butt joint process of the weld, the butt joint of the tail end of the front roll and the head end of the rear roll is prone to deviation, resulting in uneven butt joint and affecting the welding quality.
