Welding: 1150 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.

1150 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.
