A method for vertical welding of aluminum wherein a cavity is formed between aluminum plates by placing graphite retaining members on the outside surface thereof. At least one non-consumable guide tube is placed in the cavity and a consumable wire is passed therethrough. A halogen base flux is fed into the cavity to shield the weld puddle and to provide a medium for resistance melting. Voltage is supplied to the wire from about 40 volts and 1,300 amps to about 75 volts and 400 amps. When multiple guide tubes and wires are used, the wire is skewed prior to entry into the non-consumable guide tube and rotated as it emerges therethrough to ensure complete fusion.
