Abstract
The present disclosure concerns a method for assembling aluminum alloy parts, in which(i) at least a first aluminum alloy part is procured in a solution heat treated, quenched, optionally cold worked, and naturally aged at ambient temperature or pre-aged temper, and at least a second aluminum alloy part,(ii) said parts are welded to obtain a welded assembly having a welded zone,(iii) cold working the entire welded zone between 0.3% and 5% is performed,(iv) the welded assembly thus cold worked undergoes post-weld aging to obtain a final metallurgical temper.
