WELDING METHOD OF ULTRA FINE METAL WIRE WITH ALLOY FINE WIRE OF HIGH MELTING POINT, AND JOINED BODY OF FINE METAL WIRE WITH ALLOY FINE WIRE OF HIGH MELTING POINT

摘要

PROBLEM TO BE SOLVED: To provide a technology of welding an ultra fine metal or alloy wire of the melting point 2,000°C in an open atmosphere, and a joined body thereby.;SOLUTION: The diameter of a wire of a metal or an alloy of high melting point is in a range of 10-100 μm, and the butt angle of fore ends of wires is ≤20°. The welding is executed by adjusting the output of the high voltage micro discharge in the gas atmosphere in which inert gas of CO₂ or N₂O, or H₂ reduction gas is mixed under the open atmosphere.;COPYRIGHT: (C)2013,JPO&INPIT
