What kind of welding socket is used for copper, aluminum and argon arc welding?

Copper-aluminum argon arc welding can not be used, because the melting point difference between the two is too large, and the physical properties are too different, so brittle substances are formed during welding, which leads to cracks and is difficult to form.

Copper-aluminum welding generally adopts flame welding, and generally adopts copper-aluminum covered electrode, such as low temperature 5 1 welding wire 175 degrees, low temperature 480 degrees, Viodine ALCU copper-aluminum covered electrode, etc. This kind of welding belongs to brazing application, not argon arc welding.

To sum up, the copper-aluminum welding method is as follows:

Method 1: Viodine ALCU copper-aluminum covered electrode solves copper-aluminum welding.

Description: A kind of copper-aluminum welding wire with self-brazing fluoride is favored by operators in the welding process because it does not need to use any welding powder and flux. When the temperature of the base metal reaches 400 degrees, the welding wire is slightly ignited with the end of the flame, and the molten welding wire will flow like water under the action of powder. Because of its excellent fluidity, it is especially used in refrigeration industry, such as copper-aluminum tube seat, aluminum tube seat and aluminum tube seat. In addition, the lap joint and corner joint of copper-aluminum bus are also widely used in transformer industry. How to make the connected bus work in the environment of high voltage and high current, the compactness of welding layer is particularly important.

Method 2: M5 1+M5 1-F low-temperature copper-aluminum covered electrode, and solve the problem of 179 degree low-temperature copper-aluminum welding.

Description: It belongs to low-temperature brazing copper-aluminum welding, which is the most suitable welding method under extremely thin or even exaggerated conditions. However, field experience proves that the products to be welded must have a welding angle. If the welding angle is not good, the welding effect will be compromised, because the principle of this kind of copper-aluminum welding wire is completely formed by the heat-conducting melting wire of the base material, and a bad angle will lead to welding failure. Mainly used for irregular welding, one-step molding is better, and copper-aluminum enamelled wire welding, especially for electronic products and motor products.
