We developed an apparatus for the particle assemblage that makes it possible to deposit and to weld a fine particle on a desired position using a microprobe. We have already shown that gold and nickel alloy particles can be welded. In this report, other metal particles are welded at the point of Re-W needle of 125μm in diameter. Ag-Pd-Cu alloy particles of 40μm can be welded by replacing the probe of 35μm to that of 660μm. Defects were not observed at the welded interface. The heat affected zone is shown to be very narrow by EDX analysis.
