Aluminum can be used to weld metal shells using the following welding methods and welding materials:

Manual arc welding, commonly known as hand-held electric welding, is more suitable for argon arc welding. Or the welding method used when the gas welding angle is not good or the welding material is not good, you need to use DC reverse welding. The welding rod can be welded with WEWELDING555 aluminum electrode suitable for ordinary inverter DC spot welding machine.

If aluminum alloys first emerged in the aviation industry, then in recent decades, in addition to the aviation industry, they have also been used in aerospace, automobiles, ships, bridges, machinery manufacturing, electrical engineering, chemical industry and cryogenic devices. Aluminum and aluminum alloys have been widely used in the industry to manufacture various components, fuel tanks, corrosion-resistant containers, wires, etc.

Extended information:

The production and storage environment of aluminum alloy must be dustproof, waterproof and dry. The ambient temperature is usually controlled above 5°C, and the humidity is controlled below 70%.

Try to ensure that the humidity of the welding environment is not too high. Too high humidity will significantly increase the probability of pores in the weld, thus affecting the welding quality. The violent flow of air will cause insufficient gas protection, resulting in welding pores. Windshields can be installed to avoid the influence of indoor drafts.

Attention should be paid to the use of welding consumables: aluminum welding wire should be stored separately from steel welding consumables, and the service life should not exceed 1a. After welding is completed, the welding wire must be taken out of the welding machine and sealed to prevent contamination. Air supply hoses made of different materials have different abilities to resist the entry of moisture. Especially when the air supply pressure is high, the impact of the air supply hose is more obvious. It is best to use Teflon hose for the air supply hose.
