Diode lasers are used in various joining processes in industrial series production. High firmness and low warpage are the characteristics of laser welding with our lasers. Also, at high cutting speeds, excellent seam surfaces at the workpiece can be achieved, with a difference between heat conduction welding and keyhole welding.
Heat conduction welding with diode lasers is often used at workpieces with low material strength such as thin sheets, foils or wires. The laser beam is absorbed at the workpiece surface and the required energy is led to the workpiece only by heat conduction. The created smooth and rounded welded seam must not be post-processed. The method is, for example, suitable for sheet metal working of materials such as stainless steel, especially for manufacturing products that have high demands for the optical quality of welded seams in the visible field.
