    摘要: A metallic press die having an edge portion or high pressure portion for processing a workpiece therewith is made by overlaying a welding material to that portion of a base material for the metallic press die which forms the edge portion or high pressure portion, and then machining an overlaid portion into a predetermined shape of the edge portion or high pressure portion. The welding material has a hardness after welding of HRC 45 or below. After the machining step, the overlaid portion is subjected to a subzero treatment to increase the hardness of the overlaid portion. The welding material contains, as a basic composition thereof, 0.5-1.5% by weight of carbon (C), 0.2 -2.0% by weight of silicon (Si), 0.3-6.0% by weight of manganese (Mn), 0.3-10.0% by weight of chromium (Cr), 0.3-10.0% by weight of cobalt (Co), and the remaining parts of iron (Fe) inclusive of unavoidable impurities, and wherein a starting temperature of martensitic transformation is 150 .degree. C. or below.

    摘要: A pulse current from a pulse current supply side is fed to a middle part of an anode holding body to which anodes are connected; both end portions of a cathode holding body, to which cathodes are connected, are connected to a negative pole on the pulse power source side; and inductances of wiring between adjacent anodes and inductances of wiring between adjacent cathodes are set at a ratio of 1:2:3:4 in a direction of spacing from a connection to the pulse power source side. Pulse currents are equally fed to each work and it can be ensured that chromium plating treatment of each work is made equal.
