Abstract
A method of joining or repairing metal surface structures. Joinder and/or repair of metal or metal-polymer laminate panels may be carried out using so-called 'cold metal transfer' gas metal arc welding techniques. Moreover, suitable zinc-copper-aluminum alloys may improve weldability, durability and strength. The reduced thermal input permits effective weld formation at the metal sheet layers without giving rise to temperature gradient sufficient to significantly damage the interior elements.
