<p>The invention relates to a method of manufacturing a consumable filler metal in the form of wire, rod, or stick, and the like, of predetermined length and cross-section for use in a welding operation, and wherein the method comprising the steps of: providing an ingot of a first metal and one or more different further metals; forming a composite product by providing the ingot of the first metal with one or more hollow cores in substantially parallel relation to each other and locating in the hollow cores the different further metal or metals; applying pressure to the composite product to reduce its cross-section to a predetermined cross-section to form feedstock; optionally further deforming the feedstock by means of mechanical pressure to form wire, rod or stick, of final cross-section so that the ultimate alloying stage of the first metal with the different further metal or metals is performed when the wire, rod or stick is used as filler material or consumable electrode during a welding operation. The invention further relates to the use of the filler metal obtained by the method of this invention for welding an assembly of aluminium members.</p> |
