Aluminium Datasheet from Austral Wright Metals
Alloy 5083 is readily welded by the TIG and MIG processes using 5183 5356 or 5556 filler alloys. Welding the H116 temper will reduce the tensile and yield strengths in the heat affected zone to those of the annealed condition. Aluminium must be very dry & clean to avoid contamination & porosity of the weld.
