Abstract
PURPOSE: To obtain homogeneous weld metal, eliminate loss of powder and improve workability by supplying metal powder or ceramics powder from a powder supply nozzle which has been formed to spiral groove form to the plasma arc center part.
CONSTITUTION: Plasma gas 21 and shield gas 51 are supplied from cylinders not illustrated. Also, a pilot arc is generated at the end of an electrode 2 and the orifice portion of an electrode 30 by applying voltage from a power source 6 to the W electrode 2 and copper electrode 30. Next, a plasma arc is generated through the plasma gas between the base metal 1 to be welded and the electrode 2 by closing the circuit of a welding power source 7. Next, metal powder or/and ceramics powder is sent into this arc to let weld metal 11 to form on the surface of base meal 1. Here, a cooling water jacket 31 and spiral groove 32 are provided to the copper electrode body 30 to allow the foregoing powder to pass through the groove 32 and swirl, thereby concentrically supplying the powder toward the center of the plasma arc column and making the powder perfectly to the weld metal.
