Abstract
A device for the laser weld joining of sheet metal strips includes the following elements: a main frame, a laser welding unit including a laser beam generator for welding the sheet metal strips to be joined and a welding head, a clamping jaw unit supported by the frame and used to clamp the sheet metal strips, and a shearing unit for shearing the head and tails of the sheet metal strips to be joined. The shearing unit includes upper blades mounted to a blade holder and lower blades which can move in relation to the upper blades and which are designed to shear a strip, as well as a blade connecting structure fixed to the frame, the above-mentioned welding head being mobile between the blade holder and the lower blades.
