For over 100 years, welding and cutting gases have been at the heart of Air Liquide’s offers. Over time, our technologies and know-how have evolved to meet the changing needs of our customers. We continually adapt our gas solutions to respond to the challenges of metal fabrication and assembly manufacturing processes.
Welding and Cutting at a Glance
Welding and cutting are industrial fabrication processes used to transform raw materials - plate metal, tube stock, etc. - into machines and structures.
Cutting is used to separate pieces of metal sheets, structures and pipes. This is achieved by using flame, plasma or laser cutting where the gas is an active component to melt, burn, vaporise or blow away excess material, thereby creating clean cut edges.
The right gas for each particular situation
Welding joins workpieces, usually metals, by melting their edges so that they fuse together. The main process is arc welding. For this process, a gas is required to shield the liquid pool from the ambient air. Argon-based mixtures are the main industry shielding gases.
To accompany our gas solutions for welding, we also offer a wide range of gas handling and welding equipment, hardgoods and safety products, as well as a global network of hundreds of Welding & Cutting Specialists that assist customers with programs aimed at reducing cost of operations, and optimising for quality and speed.
