What's the difference between aluminum welding and argon arc welding?

Argon arc welding can be used to weld stainless steel, ferrous metal, stainless steel, superalloy, titanium alloy, aluminum alloy and other materials, and can be used in nuclear energy, aerospace, shipbuilding, electronics, metallurgy and other industries. Aluminum welding is suitable for welding aluminum and aluminum alloys.

2. Use different materials:

Argon arc welding is a welding technology with argon as shielding gas, also known as argon shielded welding. Argon shielding gas is introduced around arc welding to isolate the air in the welding zone and prevent the welding zone from oxidation. The earliest welding technologies suitable for aluminum are hydroxyl fuel gas welding and resistance welding. Aluminum arc welding is mainly limited to SMAW (manual arc welding), sometimes called MMA.

3, the working principle is different:

The working principle of argon arc welding in main circuit, auxiliary power supply, driving circuit and protection circuit is the same as that of manual arc welding. I won't describe it here, but mainly introduce the unique control function and arc initiation circuit function of argon arc welding machine. Various technologies and welding processes are used to make aluminum and aluminum alloys weldable. These two processes are laser beam welding (LBW) and friction stir welding (FSW).
