Are brazing and aluminum welding easy to learn? I want to learn brazing and aluminum welding, but I don't know if I want to learn it easily. How long will it take me to learn? Please answer me if you know, thank you. Copper-aluminum welding is very easy to learn, and there is not much operation technology in itself. As long as you can operate gas welding, you don't need a period of practice and training like argon arc welding.

Let me introduce two mainstream copper-aluminum welding.

Methods 1: ALCU-Q303 Copper-aluminum covered electrode was used to solve 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: WE53 solid solder can solve the welding of all white metals, but aluminum alloys are widely used, especially including the welding of aluminum alloys and various cast aluminum, including copper-aluminum welding, aluminum-iron welding and dissimilar welding of aluminum and stainless steel.

Note: Because WE53 is a solid welding wire, WE53 low-temperature aluminum welding wire has two operation modes.

Welding method without welding powder: welding powder and flux are not needed in the welding process, which is mainly used to solve the welding of aluminum alloy and is very suitable for welding products with special deformation requirements. When the base metal temperature reaches 400 degrees, wipe the welded joint with WE53 like rubber to form, and the welding place is the formed weld. Repair welding of water tank, intercooler root, air conditioning pipe, pipes with bad angle of refrigerator, thickness junction, etc., especially suitable for auto repair industry.

Method 3: M5 1+M5 1-F low-temperature copper-aluminum covered electrode, and solve the 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.
