oxyacetylene welding

By 1916 the oxyacetylene process was well developed, and the welding techniques employed then are still used. The main improvements since then have been in equipment and safety. Arc welding, using a consumable electrode, was also introduced in this period, but the bare wires initially used produced brittle…

The introduction of the oxyacetylene welding torch as a sculptor’s tool revolutionized metal sculpture in the 20th century. A combination of welding and forging techniques was pioneered by the Spanish sculptor Julio González around 1930; and during the 1940s and 1950s it became a major sculptural technique, particularly in…

…used as a fuel in oxyacetylene welding and the cutting of metals and as raw material in the synthesis of many organic chemicals and plastics; its chemical formula is C₂H₂.

…led him to perfect the oxyacetylene torch, which achieves the extremely high temperatures required for welding and cutting metals.
