Cutting and welding is used in infrastructure development and the manufacturing sector, and especially in the production of pipelines, vehicles, ships, and heavy equipment.
The gases industry and welding sector have enjoyed mutual benefits from growth and expansion. Demand for welding services has driven innovation in hardgoods, plants and in other equipment that welding needs. Added to this, safety regulation has played a part in the gas industry’s relationship with welding.
Acetylene, argon, carbon dioxide (CO₂), helium, hydrogen, nitrogen, oxygen and other ‘shielding gases’ are generally considered the core gases involved in cutting and welding operations, with acetylene perhaps the most well-known. Large quantities of oxygen, nitrogen and argon are used in the steel and metal industry, while shipyards and the automotive industry use acetylene, propane and other fuel gases, as well as oxygen for cutting, and mixtures of argon and CO₂ for welding.
