[The use of a focused arc welding technic for gold and cobalt-chromium-molybdenum alloys].

Joint work on small amounts of dental alloy Au-Ag-Cu (10 x 10 x 1 mm) and Co-Cr-Mo (20 x 10 x 1 mm) is relatively simple with the microplasma welding technique. The welding results are good after a short practice period. The welding technique should be improved in two points. The suitability and reliability of welding should be studied.
