Various metals can be welded, including steel, stainless steel, aluminum, copper, and titanium. The type of metal being welded and the welding technique used will determine the welding process, filler material, and equipment required.
Welding rods and wires come in various materials and sizes, including mild steel, stainless steel, aluminum, and flux-cored. The type of material being welded and the welding technique used will determine the appropriate rod or wire to use.
Welding gases such as argon, helium, and carbon dioxide are used to shield the welding area from the surrounding air, preventing oxidation and ensuring a clean weld. Different gases are used depending on the welding method, material being welded, and desired welding outcome.
