An apparatus for the welding of fine particles using a tungsten microprobe was constructed. The welding is carried out as follows. When the voltage is applied to the probe in contact with the particle, the particle is weakly welded on the substrate by the electrical discharge between the particle and the substrate. On the other hand, tough welding is obtained by the elctrical discharge from the probe placed about 20-50μm above the particle. In this paper, the apparatus and the merits or features of the welding procedure are introduced, and the effects of pre-heating for welding are discussed.
