Welding is a fabrication process that joins together two materials, more often than not two metals, by causing coalescence. Coalescence is achieved by melting the two workpieces at the point where they are to be bonded to form a common ‘weld pool’ of molten material (a filler material is sometimes also added). When the pools cools down to form a solid, the two pieces are joined together by a strong joint. The same can also achieved by using a combination of pressure and heat or sometimes just pressure to form the weld. Many energy sources can be used for welding including an electric arc, a gas flame, a laser, an electron beam, friction and ultrasound.
Welding is not to be confused with soldering, where two pieces are joined together by melting a filler material with a much lower melting point between them, without having to reach the high temperatures needed to melt either workpieces.
A form of solid-state welding, forge welding has been used by blacksmiths for centuries and was the only form of welding until the late 19th century when modern welding techniques started to develop. Arc welding and oxyfuel welding were the two earliest new techniques, followed by electric resistance welding.
Welding technology advanced quickly during the first half of the 20th century, due mainly to the demand for reliable and inexpensive welding methods during the two world wars. After the second world war several modern techniques such as shielded metal arc welding were developed, many of which are still used today. Even now new welding methods are being developed, and the science continues to advance through such new techniques as robot welding.
