Abstract
An apparatus for and method of welding aluminum members substantially vertically is provided wherein a groove-defining surface is formed on each of the members and such members are positioned adjacent each other with the groove-defining surfaces cooperating to define a substantially vertically extending groove. A gas-metal arc torch having a consumable electrode and means for supplying a shielding gas therearound is placed with the electrode in the groove, whereupon a welding arc is generated and the torch is moved substantially vertically along the groove while holding the torch at a backhand torch angle. The consumable electrode and shielding gas are fed at predetermined rates therefor while moving the torch and welding arc substantially vertically along the groove to produce weld metal in the groove having an outside oxide support skin and the oxide support skin is the only support required for the weld metal during its solidification.
