Heat treatment

Air Liquide draws on its extensive knowledge and technical expertise in heat treatment to provide customers with competitive gas solutions that are safe, reliable and fine-tuned to their needs. Our staff is on hand to support and optimize customers’ processes and control their costs.

Inert gas blanketing (SPAL)

Our SPAL technology helps producers of steel products to melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower rejects.

The technology uses liquid cryogenics (argon or nitrogen), to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen, water vapor, and carbon dioxide during air melting operations.

Laser cutting

For laser cutting, a laser beam is focused on the base metal, and a cutting jet ejects the molten metal. This process is used mainly on thin metals requiring high precision and high productivity. Air Liquide can provide you with optimized and innovative gas installations and gas equipment to meet all your flowrate and pressure needs for lasing gas and process gases. Air Liquide’s LASAL™ premium gases improves performance and reliability of specialized laser cutting jobs.

Flame cutting

Our solution for flame cutting includes FLAMAL™ brand gases, an oxy-fuel flame and straight oxygen to form a cutting jet. The high flexibility of this process combined with its excellent cutting performance makes FLAMAL™ ideal for both manual and automatic flame cutting operations for use in metal fabrication, shipyards, boilers, scrapping, and installations.
