Just like the the copper wire above aluminum foil can be used in the same fashion. After each weld cycle the foil coupon is vaporized and another coupon is indexed into position. The trickwelding together two pieces of aluminum foilis performed by Ron Covell owner of Covell Creative Metalworking.
Thats a pretty tall order in thin material.
Hot cracking sensitivity often can be avoided by adding the appropriate filler wire or inlaid filler foil material thereby altering the weld chemistry away from the crack-sensitive peak see Figure 2.

While ac power supplies can be used for welding aluminium alloys inverter DC power supplies have been suggested as providing greater control of the short time welding pulse and thus improved weldability. I would use a propane torch and cover the sheet seems with flux extending it out from the seem a bit and melt solder over the seem and drop the solder onto the seem.
