A, flame brazing conventional welding method is as follows.
1, 4047 aluminum-silicon welding wire with low temperature of 580-620 degrees and 20 1 flux is suitable for customers with certain basic gas welding skills.
2. The low temperature of 2.Viodine Q303 welding wire is about 430 degrees, which is suitable for high-purity aluminum and aluminum alloy. The higher the purity, the better the tiling effect.
WEWELDING53 welding wire with low temperature of 3.385-400 degrees has low temperature and is not picky about the base metal, but it needs to be welded with a special brush for stainless steel root.
4. The welding wire M51low temperature 179 degrees is welded with M5 1-F flux. Because of its low temperature, it is generally suitable for welding small sheets that are difficult to see flame, and it is picky about materials, and is suitable for welding pure aluminum with high purity, such as aluminum wire and aluminum enameled wire.
Second, aluminum argon arc welding.
A welding method of fusion welding, which uses argon as protective gas, melts the matrix by arc, and welds by adding welding wire according to the principle of cathode crushing. Conventional aluminum welding equipment WSME3 15B, WSME400B, including industrial WSME500G, welding wires are divided into pure aluminum series 1070, aluminum-magnesium alloy series 5356, 5 183 and aluminum-silicon series 4043.
Three, aluminum pulse gas shielded welding.
The pulsed power supply through pulsed gas shielded welding, such as MIG500 and 350, uses high-purity argon arc welding and DC reverse connection to carry out MIG welding.
