Welding Tech

Annealing operation used in connection with the change of white cast iron to a malleable cast iron.

A test in which a specimen is prepared with a fine finish, etched, and examined under low magnification.

Stick electrodes that have coating ingredients that are very low in hydrogen content. The low hydrogen level is achieved primarily by keeping the moisture content of the coating to a bare minimum.

A non-filler metal electrode used in arc welding and cutting, consisting of a carbon or graphite rod, which may be coated with copper or other materials.

Steels containing small amounts of alloying elements (usually 1«% to 5% total alloy content) which drastically improves their properties.
