  • Method for repairing steel spray-formed tooling with TIG welding process
    Patent number: 6297466
    Abstract: A machine tool or die that is fabricated from thermally spray-formed steel is repaired on the factory floor by first cleaning the area to be repaired to removed all dirt and impurities. Next the surface is prepared by means of preheating the surface with propane torches at a rate not exceeding 50° Centigrade per hour to boil off the moisture in the tool. The weldment is formed by the TIG welding process and then finished by conventional machining, grinding and polishing.
