Welding: 1070
is readily welded by the TIG and MIG processes. Commonly used
filler alloys are 4043 and 1050. 4043 gives a greater weld strength,
but if the assembly is to be anodized, 1050 filler metal will
give a closer color match.
1070 may also be
gas welded or resistance welded, but the resulting joints are
not as strong or as corrosion resistant as the inert gas welded
joints. Moreover, gas welding could result in excessive heat distortion
and, in thinner gauges, may burn through. It is essential that
all traces of flux used in welding or brazing are removed by scrubbing
with hot water upon completion.
Annealing : 350ºC
± 5ºC, until all parts have reached the annealing temperature.
Weight Calculation
: Weight per square metre in kilogrammes: 2.71
x thickness in mm.
