Welding & Metal Fabrication
Sparking productivity
At Linde, we are a trusted provider of industrial gases, applications, products and services that support welding, cutting and other processes. Our ProStar® product line includes welding supplies, cutting machines and automation from a large variety of manufacturers, and our strategically distributed plants and hubs allow us to efficiently supply our customers with our full range of industrial and process gases. But our service goes beyond providing high-quality products. We are an overall solutions provider and through our exclusive StarSolver® Productivity Enhancement Program, we work with you to reduce manufacturing costs, increase productivity and improve quality. We also have five R&D centers dedicated to developing new technologies that help you do just that.
Related Gases
Argon
Used to create an inert gas shield, argon is often blended with other industrial gases like carbon dioxide, oxygen, helium, hydrogen and nitrogen to enhance arc stability and improve the characteristics of gas metal arc welding. Argon is also the primary gas used for the gas tungsten arc welding (GTAW).
Carbon Dioxide
Carbon dioxide is most often mixed with argon as a shielding gas used to prevent atmospheric contamination of molten metal in gas metal arc welding (GMAW) process.
Oxygen
Oxygen is used as a plasma cutting gas, an assist gas for laser cutting, and is sometimes added in small quantities to shielding gases for both carbon and stainless steel welding.
Helium
A inert industrial gas with high thermal conductivity, helium shields the molten weld pool and prevents oxidation when increased heat input is desired during the welding of metals like aluminum, stainless steel, copper and some magnesium alloys.

Products
Welding Equipment
We offer a full line of welding supplies and products. From clamps and power tools to arc equipment and protection, we have the welding supplies and equipment you need to work safely and efficiently.
Hydrogen
Hydrogen is the lightest of all the gases. Used to enhance plasma welding and cutting operations, it is commonly mixed with argon for welding stainless steel because of its oxide reducing characteristics.
Nitrogen
Nitrogen can be used as an assist gas for laser or plasma cutting and as a component of shielding gas for some stainless steel welding applications.
Acetylene
Mostly used for oxy-fuel cutting and brazing applications, acetylene offers the hottest flame temperature of all commercially available fuel gases.
StarFlame™ C Cutting Gas
An alternative gas for oxy-fuel cutting, StarFlame C offers safe operation under the harsh conditions of thick cutting carbon steel. This gas can also be used in a CNC oxy-fuel application which can be supplied in a bulk form.
