Abstract
PURPOSE: To form a welded metal of high hardeness efficiently on the surface of base metals by supplying welding materials in the form of powder by means of an inert gas as a carrier gas into the plasma arc.
CONSTITUTION: If cooling water 18, 21, a shielding gas 24 and a plasma gas 19 are beforehand supplied, and voltage is increased gradually by closing the circuit of a pilot arc power source 16, the arc is generated between a nonconsumable electrode 11 and a pilot arc electrode 12. Next, when the circuit of a welding power source 17 is closed, the arc of DC reverse polarities is generated between the base metals 10 and the nonconsumable electrode 11. If the arc voltage is gradually increased and the flow rate of the plasma gas 19 is increased, the plasma arc 20 is generated between the base metals 10 and the nonconsumable electrode 11. Thereupon, when powder mixture 22 is supplied together with an inert gas to a powder supply nozzle 13, the powder mixture 22 enters the plasma arc and the alloy powder of a low m.p. melt-sticks on the base metals 10, then the carbide powder of a high m.p. disperses and enters the inside of this deposited metal, thereby forming a build-up weld zone 23.
