Quick Summary

An acetylene torch emits a bright flame as it cuts through a steel beam, with sparks and molten metal scattered on the work surface. — acetylene torch Acetylene torch being used to cut steel.

Oxyacetylene welding is a fusion welding process that uses a flame produced by burning acetylene in oxygen to melt and join metallic parts. This method was well-developed by 1916 and remains in use today, with improvements primarily in equipment and safety.12

The oxyacetylene torch, developed in 1901, produces an intense flame capable of reaching temperatures around 3,500 °C (6,300 °F). This process is particularly useful for fabricating structural steel components. While other welding techniques exist, such as arc welding and resistance welding, oxyacetylene welding is a significant thermochemical process in metal joining.21

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…

Direct metal sculpture
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…
