Electric arc high-alloy metal deposition

Claim 1

HIGH TEMPERATURE NON-FERROUS ALLOY ELECTRIC ARC WELDING PROCESS WHICH COMPRISES ENERGIZING A WELDING ARC BETWEEN THE END OF A BARE WIRE ELECTRODE COMPOSED ESSENTIALLY O F COBALT AND A METAL WORKPIECE, COATING THE END PORTION OF SAID ELECTRODE WITH POWDERED NON-FERROUS METAL PARTICLES EACH OF WHICH IS COMPOSED MAINLY OF COBALT, CHROMIUM AND TUNGSTEN, WHILE FEEDING SAID ELECTRODE CONTINUOUSLY TOWARD SUCH ARC BY CONTINUOUSLY FEEDING WHICH POWDERED METAL PARTICLES AROUND THE ELECTRODE IN AN ANNULAR STREAM OF INERT GAS, WHEREIN THE COBALT CONTAINED IN EACH PARTICLES ACTS AS A MAGNETIC COMPONENT, CAUSING SUCH POWDERED METAL PARTICLES TO ADHERE AS A COATING ON THE WIRE ELECTRODE AS THE LATTER IS SO-FED TOWARD THE ARC, WHILE SUCH ANNULAR STREAM OF INERT GAS PROTECTS THE SUCH COATING, ARC AND WELD ZONE FROM THE SURROUNDING ATMOSPHERE, THE RATIO OF METAL DEPOSITED BY THE POWDERED METAL BEING SUBSTANTIALLY EQUAL TO THAT DEPOSITED BY SAID ELECTRODE TO PRODUCE A SOLID SUBSTANTIALLY SLAG-FREE WELD DEPOSIT COMPOSED OF HIGH TEMPERATURE ALLOY THAT IS EXCEPTIONALLY HIGH
