Welding and Cutting
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.
Our Gas Solutions
Air Liquide understands the unique nature of its customers’ needs and brings them the right gas for their particular situation.
To this end, we supply welding and cutting premium gases to actors involved in the following industries:
- Metal Fabrication
- Construction and infrastructures
- Automotive
- Aeronautics
- Energy
- Workshops and repair
For these industries, our primary offer is based on three leading gas ranges:
- ARCAL™ for arc welding (TIG / MIG or MAG processes)
- FLAMAL™for oxy-fuel cutting and for flame heating or braze-welding (oxyacetylene welding)
- LASAL™ for laser cutting and welding
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.
