Welding - Wikipedia
Welding is a fabriion process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.

It does not become harder with time – it does not have a ‘shelf life’. Properties A summary of the properties is shown from the annealed (soft) condition to hard. Tensile strength: 222-385 N/mm 2 0.1% Proof strength: 60-325 N/mm 2 % Elongation: 60-4
Wire bonding - Wikipedia
Copper wire does pose some challenges in that it is harder than both gold and aluminum, so bonding parameters must be kept under tight control. The formation of oxides is inherent with this material, so storage and shelf life are issues that must be considered.
Advanced Welding Supply Company Inc. - GMAW vs. FCAW
