Welding:
5083 is readily welded by the TIG and MIG processes using 5183, 5356
or 5556 filler alloys. Welding the H116, H323 and H343 will reduce
the tensile and yield strengths in the heat affected zone to those
of the annealed condition.
Annealing: 350º
C until all parts have reached the annealing temperature.
Weight Calculation:
Weight per square metre in kilogrammes: 2.66 x thickness in mm.
