ABSTRACT:
A drive shaft assembly includes an aluminum torque tube and aluminum yokes that are arc welded to the ends of the torque tube. The torque tube has a hollow cylindrical end portion at each end that is pressed onto an annular end portion of the respective yoke to form a narrow annular slit. The two parts are then arc welded together by forming an electric arc between the parts at the narrow annular slit and a consumable aluminum based electrode. The electric arc is sustained with a pulsed high amperage direct current to fill the narrow annular slit with aluminum based material from the consumable electrode in a single pass.
