WELDING & CUTTING GASES


As a manufacturer of industrial gases, we not only deal with those processes that involve the use of industrial gases, but also with processes that are in competition with this. ELME MESSER GAAS’s advisory service on shielding gases for welding will gladly show you which shielding gas is the right one for your application: in a personal consultation and through on-site demonstrations.
