Welding Terminology

Arc Cutting - cutting of metal using the high temperature generated by an electric arc.

Arc Gouging- when a bevel or groove in formed during the arc cutting process.

Arc Welding - a technique in which metals are welded using heat produced by two electrodes or one electrode reacting with the metal that in turn creates an electric arc.

Fabrication - building metal structures by cutting, bending, and assembling.

Flux Core Arc Welding- is a semi-automatic or automatic arc welding process that requires a consumable electrode which contains a flux and a constant-voltage or a constant-current welding power supply.

Gas Metal Arc Welding - a welding procedure that employs an electric arc to heat the joint to fusion, and an inert gas to prevent oxidation of the weld.

Gas Tungsten Arc Welding - also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld.

Grinding - the process of smoothing away excess surrounding a weld.

Iron Worker - one who works with iron or steel structures.

Machine Welding- welding with a machine under the control and observation of an operator.

Shielded Metal Arc Welding - informally known as stick welding, is a manual arc welding process that uses a consumable electrode to lay the weld.

Ship Fitting - laying out, fabricating, and positioning plates and bulkheads inside the hull of a ship in preparation for riveting or welding.

Thermal Cutting - process of severing metals by either melting with high temperatures or by chemical reaction.
 
Weld Pool- the dime-sized area where metal workpiece has reached its melting point.

Welding - to unite metals by heating and allowing the separate metal pieces to liquidate partially and fuse together.

Welding Power Supply- a device that provides a high electric current to perform welding.

Welding Symbols - set of symbols used as shorthand for describing the type of weld, its size, and other processing information.

Wire Feed Welding- The wire feed unit supplies the electrode to the work, most models provide the wire at a constant feed rate.
