What should be paid attention to in argon arc welding and aluminum welding?

Pay attention to the surrounding environment and try not to choose a windy environment. Argon arc welding can weld almost all metals, especially some refractory and oxidizable metals, such as magnesium, titanium, molybdenum, zirconium, aluminum and their alloys.

Argon arc welding is mainly used for welding aluminum and aluminum alloys, copper and copper alloys, magnesium and magnesium alloys, titanium and titanium alloys, superalloys, etc. It is widely used in many important industrial sectors.

The working principle of argon arc welding is the same as that of manual arc welding in main circuit, auxiliary power supply, driving circuit and protection circuit. Besides electric shock, burn and fire similar to covered electrode arc welding, argon arc welding also has high-frequency electromagnetic field, electric shock radioactivity and arc damage much stronger than arc welding.

Extended data:

According to the difference of covered electrode, argon arc welding can be divided into two types: melting argon arc welding and non-melting argon arc welding.

1. Non-melting electrode: Argon arc welding with non-melting electrode means that the arc burns between the non-melting electrode (usually tungsten electrode) and the workpiece, and inert gas (usually argon gas) which does not react with the metal flows around the welding arc to form a protective gas cover, so that the tungsten electrode, arc, molten pool and high-temperature metals adjacent to the heat affected zone are not in contact with air, which can prevent oxidation and absorb harmful gases.

So as to form a dense welded joint with excellent mechanical properties.

2. Melting electrode: the welding wire is fed through the wire wheel, and the conductive nozzle conducts electricity, so that an arc is generated between the base metal and the welding wire, so that the welding wire and the base metal are melted, and the arc and the molten metal are welded under the protection of inert gas argon.
