How to use copper and aluminum flux cored wire

Northeast Asia copper-aluminum welding materials are simple in operation process, convenient to use, and have strong fluidity. No professional welding equipment and workers are needed. The most common flame brazing (oxygen acetylene, oxygen propane or oxygen liquefied petroleum gas) can be used to easily complete the welding. The following two welding processes can complete the welding of copper-aluminum or aluminum-aluminum:

1.Copper and aluminum flux cored wire

After pretreatment of degreasing and rust removal, move the welding torch to evenly heat the parts to be welded. When the temperature reaches about 420℃, add flux-cored wire to make it heated and melt and flow into the joint evenly. After the weld is full, remove the torch and cool down. That's it.

2.Flux paste is matched with brazing wire

After the pretreatment of degreasing and rust removal, apply the flux paste to the part that needs to be welded, move the welding gun to evenly heat the part that has been coated with the flux paste, the flux paste gradually changes from the original paste to a white solid, and then heat When the white solid is melted into a liquid state (transparent), add the brazing wire, let the brazing wire melt evenly at the welding part and flow into the joint. After the weld is full, remove the welding torch and let it cool.
