Abstract
A method is disclosed for building up a layer of metal on a metal object which comprises the steps of: positioning a mold on the object having a cavity of the desired configuration of the layer to be formed; feeding a consumable filler electrode having a flux core into the mold cavity while providing an electric arc between the electrode and the object; cooling the mold to rapidly solidify the flux transferred from the core of the electrode to the cavity walls; and removing the mold when the molten metal solidifies.
Claims1
A method of building up a layer of metal on a metal object comprising the steps of:
- a. positioning a mold on said metal object in the area said layer of metal is to be deposited, said mold having a wall defining a cavity of the desired configuration of said metal layer,
- b. feeding a consumable filler wire having a core containing flux into said cavity of said mold in a predetermined manner while providing an electric arc between said wire and said metal object to melt said wire and transfer said flux to said walls of said cavity,
- c. cooling said mold to rapidly solidify said flux transferred thereto to thereby form a smooth, ceramic-like shield between said walls and said molten metal, and
- d. removing said mold when said molten metal solidifies.
