Messer is installing a liquid nitrogen supply for A. Späni AG in Raron. Späni is a specialist in uncut metalworking and already procures the cylinder gases Inoxline He3 H1, forming gas, welding argon, oxygen and nitrogen from Messer. They are needed for, among other things, tungsten inert gas welding (TIG), gas metal arc welding (MIG/MAG), AC/DC welding, robot welding and longitudinal seam welding. Sheet metal and tubular constructions made of any alloy are welded with the aid of robots at Späni. The firm also runs a Messer gas depot, where other customers can collect their cylinder gases.
