Cutting and welding innovations
Under the motto“ Precise cutting, perfect welding— complete solutions that connect and inspire,” industrial gases specialist, Messer, and Messer Cutting Systems presented innovations at the Schweissen & Schneiden 2025 trade show this September.
“ Using hydrogen as a fuel gas for oxyfuel technology reduces CO₂ emissions to zero during use and significantly reduces the emission of nitrous oxides and dust particles. At the same time, hydrogen makes it possible to achieve higher efficiency, better results as well as greater occupational safety and health,” they told ISMR.
Messer and Messer Cutting Systems have therefore joined forces to drive forward the necessary developments, including gases as well as special torches and nozzles.
Lowering emissions and improving quality are also their focus in welding. Messer also showcased solutions for handheld laser beam welding, along with an innovative shielding gas for welding unalloyed steels, at Schweissen & Schneiden.
Oxyfuel cutting with hydrogen
“ Two years ago, with Messer Cutting Systems, we were the first industrial gases supplier to commercialise hydrogen for oxyfuel technology. Marketed under the brand name HyCut, the solution uses 100 % hydrogen as fuel gas. Hydrogen contains no carbon atoms, thereby enabling oxyfuel cutting without emitting any CO₂. This helps HyCut users to meet their own sustainability goals and comply with legal requirements,” confirmed Messer.
“ HyCut makes it possible to apply heat precisely with a performance that matches or exceeds that of acetylene. The service life of the nozzles is extended and they are also easier to recycle because they require no chrome plating. Last, but not least, the noise level drops by 5-8 dB( A). In addition to flame cutting, HyCut has also proved itself in heating and straightening, brazing and flamespraying applications,” it added.

Laser cutting with nitrogen and oxygen
The sharp increase in laser power in recent years has also unveiled new market opportunities, according to Messer.
“ When cutting unalloyed steels, we can use the exothermal reaction process with oxygen to dispense with the energy share. This results in cut surfaces with less oxidation and significantly higher feed rates,” explained Messer.
“ For a long time now, nitrogen has been one of the alternatives used to produce components that require little reworking. Up until now, the disadvantages have included heavy burr formation on the underside of the components. This has now changed thanks to new mixtures of nitrogen with a 2-5 % share of oxygen,” it continued.
At the trade show, Messer presented customised solutions that optimise the use of nitrogen and oxygen, according to user requirements.
Welding in focus
“ Handheld laser beam welding is fundamentally changing the world of welding. It features high precision, low heat input, high welding speed, easy handling and minimal component distortion. We have developed a new portfolio of shielding gas mixtures for these applications and demonstrated at Schweissen and Schneiden how these gases( marketed under the brand, Lasline) can be used for handheld laser beam welding,” added Messer.
At Schweissen & Schneiden 2025, Messer presented shielding gas, Ferroline C6 X1, for unalloyed steels. This special mixture of argon, carbon dioxide and oxygen is designed to“ significantly reduce the emission of welding fumes and particles.”
This, said Messer,“ enables users to comply, simply and effectively, with increasingly demanding health protection regulations around the world.” n
