Welding

In welding, metals, like or unlike, are joined together by melting them until they fuse, “adding material” being used where it is required. The welder also builds up worn parts or adds metal where it is lacking. Common metals which can be treated by this process include the following: Cast iron, steel, malleable iron, aluminum, copper, brass, bronze, lead, and nickel. Precious metals also can be welded. Each metal has its peculiar characteristics and mode of treatment, and the welder who would turn out a good job must master the special technique for handling each metal.

Welding forms the larger part of the welder’s activities. It is much more difficult than cutting, and also has a wider field of application.
