Abstract: An apparatus for microplasma spray coating a portion of a turbine vane (72) without masking includes a microplasma gun (12) with an anode (16), cathode (18), and an arc generator for generating an electric arc between the anode (16) and cathode (18). An arc gas emitter injects gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream (21). A powder injector (22) injects powdered material into a plasma stream (21). A localized area of the turbine vane (72) is coated with the powdered material (34) without having to mask the turbine vane (72).

Abstract: A method for welding a metal part with a laser that generates a laser beam, where the method includes manually feeding successive portions of a filler material adjacent the metal part and in a pathway of the laser beam, generating the laser beam for melting the filler material, and cooling the melted filler material for fusing the filler material to the metal part. The method further includes controlling an intensity of the laser beam based on a sensed position of a user's hand relative to the laser beam.

Abstract: A microplasma spray coating apparatus includes a microplasma apparatus with an anode, cathode, and an arc generator for generating an electric arc between the anode and cathode. An arc gas emitter injects inert gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream. A powder injector nozzle extends through the anode and injects powdered material into the plasma stream for transfer to the workpiece.
