Abstract

PURPOSE: To obtain buildup metal of desired chemical composition, by sending a flexible monmetallic carrier holding powder for requried alloy into a molten pool along a strip electrode.
CONSTITUTION: At the end of a metal hoop 1, the hoop 1 is melted by the heat produced between the hoop 1 and base metal 2 to produce droplets 3. The surrounding temperature of these droplets and end part of the hoop 1 is close to the melting point of the metal, at which temperature the material of a carrier 4 is to be melted. The alloy powder held by the carrier 4 of nonmetallic material such as plastics migrates into the droplets 3 without being scattered by melting in the vicinity of the droplets 3 of the carrier material and drops into the droplets, or the droplets fall into a molten pool 5 to melt down to form an alloy. Thus, a deposited metal 6 of desired chemical composition may be obtained. Meanwhile, if the powder for alloy has a boiling point lower than the surrounding temperature of the droplets 3 or is flammable such as carbon, it is held in the carrier material until the carrier material is melted and burned, so that vaporization or combustion may be arrested by the heat of melting and vaporization thereof.
