Welding 050 Aluminum. For cryogenic propellant tanks for experimental reusable rocket vehicles. As a hull material for small aluminium boats or larger yachts.
While mig and tig are commonly used methods for welding aluminum there are several other types of welding that can be used. When comparing similar thickness materials the static and fatigue shear strengths of aluminium alloy spot welds are about one third the value of steel welds depending on the alloy type. This welding technique is often used by automotive enthusiasts and welders.

Where aluminium is used instead of steel its gauge is normally increased giving weld strengths which compare more favourably with those of steel - but still enabling weight savings to be made. A MIG welder for Aluminum will do this automatically when. 2 GTAW with back-up tab- permanent. Typically I would estimate the initial failure rate to be upwards of 95 on the first submittal.
