Welding is a fabrication or sculptural
process that joins materials, usually metals, by causing coalescence.
This is often done by melting the workpieces and adding a filler
material to form a pool of molten material (the weld pool) that cools
to become a strong joint, with pressure sometimes used in conjunction
with heat, or by itself, to produce the weld.
Many different energy sources can be used for welding, including a gas
flame, an electric arc, a laser, an electron beam, friction, and
ultrasound. While often an industrial process, welding may be
performed in many different environments, including open air, under
water and in outer space. Welding is a potentially hazardous
undertaking and precautions are required to avoid burns, electric
shock, vision damage, inhalation of poisonous gases and fumes, and
exposure to intense ultraviolet radiation.
Until the end of the 19th century, the only welding process was forge
welding, which blacksmiths had used for centuries to join iron and
steel by heating and hammering. Arc welding and oxyfuel welding were
among the first processes to develop late in the century, and electric
resistance welding followed soon after. Welding technology advanced
quickly during the early 20th century as World War I and World War II
drove the demand for reliable and inexpensive joining methods.
Following the wars, several modern welding techniques were developed,
including manual methods like shielded metal arc welding, now one of
the most popular welding methods, as well as semi-automatic and
automatic processes such as gas metal arc welding, submerged arc
welding, flux-cored arc welding and electroslag welding. Developments
continued with the invention of laser beam welding, electron beam
welding, electromagnetic pulse welding and friction stir welding in
the latter half of the century.
