Build stronger steel structures at lower cost with Messer's welding and cutting gases. The construction of buildings, factories, and bridges all requires large quantities of steel structures. Steel structures serve as the backbone of these constructions, making their quality and performance critical to the safety of these buildings. At the same time, intense industry competition compels steel structure manufacturers to strictly control production costs. Steel structure production mainly consists of two processes: cutting and welding. Messer's Ferroline® welding shielding gases and cutting gases help enterprises effectively address these challenges. Messer's Ferroline® C20 and C18 welding gases, combined with proper welding procedures, qualified base metals and welding materials, and good welding practices, produce welds with excellent performance, ensuring the safety of steel structures. Moreover, Messer's specialty welding shielding gas product—MEGAFAST® Ternary 1 gas—not only delivers high-quality welds but also increases welding speed, reduces spatter, and lowers fume emissions. Messer's cutting oxygen gas, used in oxy-flame cutting and laser cutting of steel structures, makes the cutting process smoother and produces cleaner cut edges. Furthermore, Messer's proprietary hydrogen cutting technology uses hydrogen as the cutting fuel, which not only improves cutting speed and quality but also achieves zero-carbon-emission cutting—a truly green manufacturing method that delivers both quality and economic benefits.


Sheet Metal Processing specifically refers to the fabrication of metal thin sheets with a thickness not exceeding 6 millimeters, such as carbon steel plates, stainless steel plates, aluminum plates, and copper plates. Through processes including shearing, punching, bending, welding, joining, and forming, these sheets are processed into the required shapes. Sheet metal processing is an important manufacturing method for metal products, widely applied in industrial equipment, automotive manufacturing, electronics products, building and decoration, aerospace, and medical devices.
The traditional welding methods commonly used in sheet metal processing are MAG welding and TIG welding. Among Messer's Ferroline® (梅钢保®), Inoxline® (梅合金保®), and Aluline® (梅铝保®) welding shielding gas products, many are suitable for sheet metal processing, such as Ferroline® C8, Ferroline® C6X1, Inoxline® C2, Inoxline® O2, Aluline® He1, as well as the most traditional argon. Currently, a new trend has emerged in the sheet metal industry: replacing these two traditional welding methods with handheld laser welding. Handheld laser welding offers advantages including high welding speed, fine and nice-looking welds, and convenient welding operation. These characteristics precisely match the needs of sheet metal processing and address its pain points. Handheld laser welding machine manufacturers typically recommend argon and nitrogen as welding shielding gases. However, based on its extensive experience in developing welding shielding gases, Messer believes there are other, better options available.
Messer has specially developed a series of shielding gas products for handheld laser welding of different materials, in order to fully leverage the advantages of handheld laser welding and minimize the occurrence of various defects. These gas products are named Lasline® (梅光保®). At the same time, certain gases from Ferroline®, Inoxline®, and Aluline® can also be used for handheld laser welding in sheet metal processing, enabling the sheet metal industry to perform with even greater excellence.
