A METHOD OF FORMING A WEAR-RESISTANT WELD DEPOSIT COMPRISING FORMING IN AN ARC WELDING REACTION ZONE A NICKEL BASE WELD METAL POOL, INTRODUCING INTO THE REACTION ZONE A COMPONENT COMPRISING AT LEAST ONE OF THE MATERIALS OF THE GROUP CONSISTING OF TITANIUM, TITANIUM ALLOY, TITANIUM CARBIDE AND OXIDE OF TITANIUM, ALONE OR COMBINED WITH ANOTHER OXIDE, SUCH COMPONENT CONTAINING TITANIUM IN AN AMOUNT BETWEEN ABOUT .8% AND ABOUT 16% BY WEIGHT OF THE WELD DEPOSIT, INTRODUCING INTO THE REACTION ZONE A CARBIDE FORMING MATERIAL IN AN AMOUNT SUFFICIENT TO RENDER BOTH CARBON AND TITANIUM SOLUBLE IN THE NICKEL, SAID CARBIDE FORMING MATERIAL COMPRISING AT LEAST ONE OF THE MATERIALS OF THE GROUP CONSISTING OF CHROMIUM, IRON, MANGANESE, MOLYBDENUM, TUNGSTEN, VANADIUM, COLUMBIUM AND SILICON IN AN AMOUNT SUFFICIENT TO PRODUCE A CARBIDE FORMED EQUIVALENT OF AT LEAST 3% BY WEIGHT OF THE WELD DEPOSIT AND MAINTAINING IN THE REACTION ZONE AN AMOUNT OF CARBON AT LEAST EQUAL TO THE TOTAL OF (1) THE AMOUNT OF CARBON REQUIRED TO FORM THE TITANIUM CARBIDE PARTICLES PLUS (2) THE AMOUNT OF CARBON REQUIRED TO REDUCE TITANIUM OXIDE AND OTHER METAL OXIDES REDUCIBLE BY CARBON IF PRESENT PLUS (3) THE AMOUNT OF CARBON REQUIRED TO COMBINE WITH OXYGEN DERIVED FROM THE REACTION ZONE ATMOSPHERE AND THEREBY FORMING TITANIUM CARBIDE PARTICLES BY CRYSTALLIZATION IN SITU THE SOLIDIFYING WELD METAL WHICH FORMS THE MATRIX.
