Description

Technical Field

[0001] The present application relates to the technical field of steel strip production, and in particular to an automatic welding machine for narrow overlap of steel strips. Background Art

[0002] A seam welder is a spot welding machine that places the workpieces into lap or butt joints between two roller electrodes. The roller electrodes pressurize the workpieces and rotate, applying power in a continuous or intermittent pulse to create a continuous weld. It can be said that seam welders are an evolution of spot welding.

[0003] To ensure continuous steel strip production, seam welders (or welding machines) are often used in the prior art to connect the tail of the leading coil and the head of the trailing coil. Specifically, a shearing machine is positioned in front of and behind the seam welder. These shears cut the seams of the two steel strips online, then pass the shears through them and converge on the seam welder for welding. While this welding method can achieve shearing, welding, and ultimately connecting the two coils, it is cumbersome, requires significant equipment floor space, and has a low degree of automation when used in conjunction with the welding machine.
