Aluminum and aluminum alloys are widely used in various fields because of their light weight, good ductility, easy forming and stable physicochemical properties.

In modern industrial production, for aluminum and aluminum alloy welding is generally used TIG welding.

In the process of TIG welding, the torch spraying inert gas on the electrode, ARC and weld pool protection to prevent atmospheric intrusion, thus ensuring the quality of aluminum and aluminum alloy welding.

According to the characteristics of TIG welding, the welding quality of aluminum and aluminum alloy can be improved effectively and the welding defects will be reduced.
