Abstract

1398500 Casting composite articles GREAT CANADIAN OIL SANDS Ltd 28 March 1973 [29 March 1972] 14858/73 Heading B3F [Also in Divisions El and H5] A method of hardfacing a metal workpiece 10, e.g. a tooth for an excavator, by an electroslag welding process comprises feeding consumable electrode wires 13 through at least two separate consumable guide members 15 each of which differs from the other in metallurgical composition. Thus a workpiece having a hardfacing whose composition varies according to its position on the workpiece is produced. Each guide member 15 comprises an outer shell (5) having a tube (6) passing therethrough, the space between the shell and the tube being filled with a particulate composition. In the embodiment described there are two such guide members A and B one containing 60% tungsten carbide, 30% ferrochrome, 5% ferromolybdenum and 5% ferrovanadium and the other containing 49% ferrochrome, 49% silicon carbide and 2% cobalt. Other components may include ferromanganese, ferrosilicon, ferrozircon, Ni, Cr, Mo, Ti and Zr. The apparatus used to carry out the process may comprise a bench 11 for supporting the workpiece 10, a cooled shoe 17 for defining the cavity into which the wires 13 and guide members 15 depend, a wire straightening device 20, a wire feeding mechanism 21, a power supply unit 30 and a control unit 25. The guide members 15 may be oscillated.
