Abstract:
PCT No. PCT/EP88/00686 Sec. 371 Date Feb. 13, 1990 Sec. 102(e) Date Feb. 13, 1990 PCT Filed Jul. 28, 1988 PCT Pub. No. WO89/01384 PCT Pub. Date Feb. 23, 1989.Known tool configurations for ultrasonic welding are comprised of a sonotrode as an active tool and an anvil as a work fixture for the workpieces. According to the invention, the sonotrode (1, 21, 30, 40, 50) and/or anvil (2, 22) are provided with synthetic hard material on their working surfaces (6, 9, 36, 46) through which the ultrasound is injected into the workpieces (3, 4, 23, 24) to be welded together. This synthetic hard material defines a new working surface (6a, 9a, 26a, 46a, 56a). Polycrystalline diamond, polycrystalline boron nitride, or also cubic-crystalline boron nitride come under consideration as synthetic hard materials.
