Process for joining two parts consisting of metals differing in hardness by means of laser light

摘要

there are two hu00e4rtemu00e4u00dfig between different metals 11, 21 with laser light 30 to a teilekombination are connected. the part 10 consists of a tough material 11, while the other part 20 of a tungsten carbide is 21.a particularly strong link, without cracks, to manufacture, it is proposed the two parts 10, 20 to a pressure p below the plastizitu00e4tsgrenze of tough material 11 is kept. then a laser beam 30 points on the both sides of the interface between the two parts 34 floor areas 10, 20.the intensity i and the speed v for the movement of the laser light 30 along the outline of the interface is so moving that it not only a but also for 51 to a diffusion into the adjacent zones 19, 29. the applied voltage is prevented by the pressure in the hartmetallschweiu00dfung usual cracking.
