1Gas metal arc welding — RMD redirects here. RMD may also refer to IRA Required Minimum Distributions. Gas metal arc welding …
2Twin carbon arc welding — Unlike single carbon arc welding, in twin carbon arc welding the arc is maintained between two carbon electrodes held in a special holder. Current is switched on and by operating the mechanism of arc length adjustment the two electrodes are… …
3Arc — may refer to: Computing and gaming*Arc (programming language), a Lisp dialect in development by Paul Graham *.arc, a file extension for archive files *arc, the command line interface for ArcInfo *Arc System Works, a video game… …
4welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved …
5Arc lamp — The electric arc in an arc lamp consists of gas which is initially ionized by a voltage and is therefore electrically conductive. To start an arc lamp, usually a very high voltage is needed to ignite or strike the arc. This requires an electrical …

7Electric arc — An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. The phenomenon was first described by… …
8Atomic hydrogen welding — (AHW) is an arc welding process that uses an arc between two metal tungsten electrodes in a shielding atmosphere of hydrogen. The process was invented by Irving Langmuir in the course of his studies of atomic hydrogen. The electric arc… …
9Electric resistance welding — (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the… …
10Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
