Welding Aluminum With Acetylene Torch. Oxy-acetylene welding uses a high-heat high-temperature flame that is produced by burning a fuel gas most commonly acetylene mixed with pure oxygen. Aluminum Oxy-Acetylene Welding Flux 1750.
Yes oxyacetylene torches are mostly used for welding aluminum. Instead in attempting to torch cut aluminium that oxygen immediately makes an aluminium oxide layer and inhibits the oxygen from burning the metal. He scrubbed it with sandpaper and picked up an oxy acetylene torch.
Set regulators to equal pressures from 2 to 5 pounds each with smaller tips needing lower pressures.
Most welders use RG-45 or RG-60 rods. Aluminum Oxy-Acetylene Welding Rod AWS 1100 1750. RG Rod Gas 45 tensile strength times 10000 45000 PSI RG-65 is a less commonly used low-alloy rod designed for high speed fusion welding of pressure vessels tanks and piping. Professional oxy-fuel torch welding uses either acetylene or hydrogen a good water-mixed flux and special eyewear to remove the sodium orange flare caused by the flux.
