With diode laser integral systems, higher strengths can be achieved in laser transmission welding of plastics compared to other welding processes such as ultrasonic, friction, heating element or hot gas welding. Weld seams reach max. Tensile / shear strengths through integral joining, ie chemical linking of transparent and absorbent joining partner. In this way, the basic material strength is achieved, ie the joining partners behave like a component made from “one injection molding”.

This can only be achieved through locally limited, precise and homogeneous energy supply across the weld seam width (process-optimized power density distribution).

The result is pore, spatter and absolutely particle-free welding processes, a basic requirement, for example, for electronics / sensor / medical products.
