Laser cutting

For laser cutting, a laser beam is focused on the base metal, and a cutting jet ejects molten metal. This process is used mainly on thin metals requiring high precision and high productivity. Air Liquide can provide optimized and innovative gas installations to meet your needs of high pressure nitrogen or high purity oxygen.

Laser welding

The laser beam produced by a CO₂ laser or a solid state laser is used for high-penetration, high-speed welding processes where mainstream processes cannot deliver the required distortion and/or productivity.

With Nexelia for laser welding, Air Liquide provides a all-in-one solution to reduce your production cost.

MAG and TIG welding

Metal Active Gas (MAG) welding is highly flexible and adaptive, and is used when you wish to obtain high productivity and high quality results. This process is used for manual and semi-automatic welding or automated/robotized installations on low-alloy carbon steels or hig h-alloy stainless steels. MAG welding is widely used in shipbuilding, construction and the production of heavy plants and machinery.

Tungsten Inert Gas (TIG) welding is commonly used for joining stainless steels, aluminum and aluminum alloys – enables a very high quality of welding to be achieved in particularly demanding sectors of application, such as pressure vessels and pipelines. The process uses an electric arc between the metals to be joined and an infusible tungsten-based electrode, located in the welding torch.

MAG and TIG welding

Metal Active Gas (MAG) welding is a manual or semi-automated welding process that is widely used in shipbuilding, railroad construction and the production of heavy plants and machinery. The process melts and fuses metals using intense heat generated by an electric arc between the metals to be joined and a filler wire.

Tungsten Inert Gas (TIG) welding is commonly used for joining stainless steels, aluminum and aluminum alloys – enables a very high quality of welding to be achieved in particularly demanding sectors of application, such as pressure vessels and pipelines.

Plasma cutting

Plasma cutting is used to thermally separate metallic materials that cannot be cut by a flame. It allows for a smaller cutting angle compared to flame cutting, high cutting speed, clean and smooth cutting edges, and high-quality welded joints. It is widely used on all types of metal to achieve high-quality cuts and high levels of productivity. Under certain circumstances plasma cutting can achieve a comparable quality level to laser cutting, but at considerably lower production cost.
