                              Welding & Cutting

                              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’s 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, vaporize 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:

                              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 optimizing for quality and speed.
