There are the following methods for welding copper and iron;1. Copper and iron can be welded in a variety of ways.

2. Brazing;

3, friction welding, to see what kind of specific workpiece. 

4. Common method is flame brazing, with copper wire, borax flux can be added.

5. In addition to the above two methods, we use argon arc welding and 201 electrode when welding copper plate and iron plate. The effect is also good.

For example;

Heat to a certain temperature with a flame, using a copper electrode and borax

With high frequency heating equipment, first the welding surface coated with silver flux, put the silver welding sheet between copper and iron, press, heat until the silver welding sheet melting can be
