LASERLINE Global Gas Solutions for Laser Cutting and Welding

Our LASERLINE portfolio was developed specifically to enhance productivity in laser cutting and welding. It includes laser cutting oxygen, which enables high cutting speeds in mild steel. LASERLINE laser-cutting nitrogen can be used on stainless steel to achieve clean, oxide-free cuts with no change to the material’s corrosion resistance. In addition, specialty gases from the LASERLINE program can boost your productivity when cutting aluminum and titanium.

We work closely with laser manufacturers to ensure that our LASERLINE gases meet OEM purity requirements. Moisture (H₂O) and total hydrocarbons (THC) have a significant impact on laser operation. Our strict quality assurance programs ensure tight control over these parameters (down to <5 ppm for H₂O vapor content and < 1 ppm for THC content) to meet individual laser machine needs.

Our LASERLINE process gases are used in laser welding, laser cutting, surface treatment, powder coating (as a carrier gas) and beam bath purging. The most common assist gases used for these applications are nitrogen, oxygen, argon and helium.

We provide LASERLINE assist gases in the following recommended purities to help laser processing specialists meet their speed and quality expectations. Supply modes scale from single cylinders to fully automated bulk systems to suit individual needs.

We also supply resonator gases, used for creating laser light in CO₂ lasers. These resonator gases are available as pure gases for lasers with integrated gas mixers or as premixed gas blends as part of our LASERMIX^® offering.

Our LASERLINE^® program includes a variety of LASERMIX premixed laser gases - specially blended to give you the quality you need for your laser machine. We work closely with laser manufacturers to align purities, blend tolerances and filling procedures with concrete needs.

In addition to our wide stock of standard LASERMIX gas mixtures for all major lasers, we also produce customized gas mixtures on demand at our state-of-the-art gas filling plants.

These LASERMIX gas mixtures combine carbon dioxide with other gases such as nitrogen, hydrogen, helium, carbon monoxide, xenon and oxygen - with H₂O vapor content reduced to less than 2.2 ppm and THC content below 0.3 ppm in some cases.

Our LASGON family of process gases was developed specifically for laser welding. This portfolio includes bespoke gas mixtures for the most varied of applications and materials so you can look forward to stable, safe welding operations and improved outcomes.

LASGON mixtures contain active gases in different concentrations to master just about all material challenges, covering everything from coated and uncoated materials through ferritic or austenitic steels to aluminum, copper and other non-ferrous metals. By protecting the workpiece against the atmosphere, LASGON welding process gases limit the risk of variations in the chemical properties of the workpiece and enhance the weld’s metallurgical properties. Other important benefits of LASGON shielding gases include the control of plasma formation and even the direction of the melt flow - both of which have a bearing on welding process efficiency. These benefits combine to make LASGON products particularly cost-effective - thanks to their contribution to welding speeds, quality standards and process stability.

All LASERLINE supply systems are designed to meet your individual requirements, depending on the number of lasers you have in operation, the typical materials you process, the material thickness, safety measures and gas availability. Wall-mounted cylinders or cylinder bundles with an automated changeover feature, for instance, give you continuity of supply. Reserve cylinders or bundles can give additional peace of mind. For larger volume requirements, a cryogenic gas storage tank may be the preferred option.

All components of the LASERLINE gas supply system - including pipes, fittings, hoses and regulators - are designed to maintain gas purity and pressure right up to the point of use. LASERLINE single-stage and dual-stage regulators, for instance, are approved for high-purity laser gases. They are equipped with self-purging valves, which prevent contaminants such as dust, moisture and fumes from entering your laser after cylinder change-over by purging the connections to gas cylinders. Metal housings and metal membranes allow precise adjustment of the pressure settings and prevent permeation of impurities. No sealing or adhesive compounds are used.
