It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used.
Website. millerwelds.com. Miller Electric is an American arc welding and cutting equipment manufacturing company based in Appleton, Wisconsin. Miller Electric, has grown from a one-man operation selling products in northeastern Wisconsin to what is today one of the world's largest manufacturers of arc welding and cutting equipment. [1]
A transformer-style welding power supply converts the moderate voltage and moderate current electricity from the utility mains (typically 230 or 115 VAC) into a high current and low voltage supply, typically between 17 and 45 (open-circuit) volts and 55 to 590 amperes. A rectifier converts the AC into DC on more expensive machines.
Submerged arc welding. The welding head moves from right to left. The flux powder is supplied by the hopper on the left hand side, then follow three filler wire guns and finally a vacuum cleaner. Pieces of slag from Submerged arc welding exhibiting glassy surface due to silica (SiO 2 ). Submerged arc welding ( SAW) is a common arc welding process.
An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field emission.

Electric resistance welding. Electric resistance welding ( ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [2]
