11Plasma arc welding — (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW …
12Seam welding — Resistance Seam Welding is a resistance welding process that produces a weld at the faying surfaces of overlapped parts along a length of a joint. The weld may be made by overlapping weld nuggets, a continuous weld nugget or by forging the joint… …
13Submerged arc welding — (SAW) is a common arc welding process. Originally devolved by the Linde Union Carbide Company. It requires a continuously fed consumable solid or tubular (flux cored) electrode. The molten weld and the arc zone are protected from atmospheric… …
14Twin 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… …
15Orbital welding — is a specialised area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process. Contents 1 History 2 Equipment 3 Application …
16Electrogas welding — (EGW) is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied. A major difference between… …
17Underwater welding — refers to a number of distinct welding processes that are performed underwater.cite book |author=Keats, DJ |year=2005 |title=Underwater Wet Welding A Welder s Mate |publisher=Speciality Welds Ltd |url=http://www.specialwelds.com |isbn=1 899293 99 …
18pulse arc welding — A type of welding arc in which the arc welding current is interrupted or pulsed as the welding arc progressed …
19arc welding — Welding by using an electric current to melt both the metal to be welded and the welding rod or electrode that is being added. Also see atomic arc welding inert arc welding pulse arc welding …
20electric welding — Welding by using an electric current to melt both metal (work) and welding rod, or electrode …
