Claim:
1. A method for performing a welding process on a workpiece by a welding torch, using a melting composite welding wire, the method comprising steps of: preassembling and interconnecting at least first and second welding wires in at least first and second lengths to form the composite welding wire, wherein the at least first and second welding wires have different material compositions or different diameters or different material compositions and different diameters and wherein the at least first and second lengths correspond to respective lengths of the composite welding wire used with respective different at least first and second welding parameters in the welding process, supplying the composite welding wire to the welding torch from a wire coil, and performing the welding process without interruptions using the different at least first and second welding parameters by supplying to the welding torch the composite welding wire from the wire coil.
