Abstract

The invention discloses a strip head shearing and butt welding method and a shearing and butt welding platform. The strip heads of a front coil steel strip and a rear coil steel strip are sequentially subjected to shearing, welding blocking and milling treatment; in the shearing step, the strip heads of the front and rear coil steel strips are sheared by adopting a cutter to form shear lines; the shear lines are subjected to butt joint and then subjected to blocking welding, and during blocking welding, during welding, molten steel is intercepted at the two open ends of the butt-joint shear lines through blocking structures; and in the milling step, a milling cutter is used for milling a welding seam formed by welding. According to the method, the strip head of the front coil steel strip and the head of the rear coil steel strip are treated by adopting a beveling-plugging welding-milling method, so that on the basis of reducing sinking of the opening ends, the two opening ends are intercepted by adopting the stop blocks to form plugging welding, the collapse of the opening ends of welding seams is avoided, and it is ensured that the butt joint position of the steel strips does not have the sinking phenomenon; and therefore, pits cannot be formed after the steel strip is subsequently welded and formed, raw materials are saved, the cost of the raw materials is reduced, and the yield of the raw materials is improved.

Description

technical field [0001] The invention relates to the technical field of welded pipe production, in particular to a butt shear welding method and a shear butt welding platform for steel strips. Background technique [0002] Welded pipe is welded steel pipe, which is a steel pipe made of steel plate or strip steel after crimping and welding. In the welded pipe production line, in order to meet the continuity of production, a shearing butt welding device is usually used to cut the leading ends of the front and rear steel strips neatly and then weld them to form a continuous steel strip, which is conducive to making full use of raw materials and facilitating continuous production. sex. [0003] The butt weld is formed after the steel strip head is sheared butt welded, and the arc starting point and arc landing point of the butt weld often have a concave weld, that is, there will be depressions and openings at both ends of the butt weld. That is to say, on the formed continuous ...
