[Ultimate tensile strength of plasma- and laser-welded cast titanium (Titaniumer, Ohara)].
The ultimate tensile strength (UTS) of titanium castings (Titaniumer, Ohara) as cast and after plasma-welding, laser-welding and soldering was investigated according to DIN 13912. The UTS of titanium as cast was 567 (+/- 36) MPa. After plasmawelding UTS decreased by 69% on the average, after laser-welding by 20%, after soldering with Ag65Cu20Pd15 (1060 degrees C) by 46% and after soldering with Ag72Cu20Ti8 (980 degrees C) by 63%. The highest tensile strength was observed in laser-welded titanium under the conditions described.
