Welding & Cutting Gases

Over the years, welding and cutting technologies have developed into more than 200 distinct process methods. While only a small number of these require the use of industrial gases — such as gas-shielded welding, laser welding, flame cutting, and laser cutting, they carry the bulk of metalworking operations today. These gas-based processes lie at the heart of modern manufacturing and are continually evolving to deliver greater precision, higher throughput, and more sustainable performance, all in line with the growing demand for quality and environmental responsibility. Messer provides end-to-end gas solutions for welding and cutting processes, offering a comprehensive portfolio that includes both standardized gases and gases tailored to specific applications. Leveraging global expertise and strong local engineering capabilities, we have developed a range of high-performance gas mixtures for MIG, MAG, and TIG welding, as well as laser processing of carbon steel, stainless steel, non-ferrous metals, and their alloys.
