Abstract

PURPOSE:To obtain the product of high compaction density of packing by limiting the outside diameter before and after pipe drawing and the change value of thickness at the time of producing the captioned electrode composed of the metal-made seamless pipe and powder packing so selected that the build-up weld zone has the specific composition. CONSTITUTION:If the pipe having an inside diameter Di and outside diameter Do satisfying formula I is selected and powder is packed therein where the total volume ratio of various powders to the inside volume of the metal pipe is let rhoo and the true volume ratio of the powders after packing, i.e., powder packing degree, is let S, thence if the both ends of the pipe are hermetically sealed and the pipe is drawn in such a manner that its outside diameter becomes less than the value calculated by the formula II, then the powder packing degree is enhanced to 0.80 or more and therefore the tube wire electrode which is free from possibility for unevening the quality of the build-up weld zone by the splitting down of the powder during welding is obtained.
