Most of these welding processes utilise gas to protect welds from oxidation and to ignite and maintain the welding arc. Manufacturers of welding equipment can capitalise on some of our flow meters’ features. Accurate flow and pressure control of shield- and backing gases used during your welding process will provide a constant and stable weld and thereby improve the quality of the welds.
Which gases need to be controlled in welding processes?
Welding involves using inert gases for shielding (externally) and backing welds (internally) to displace gases like nitrogen or oxygen that are detrimental for the quality of welds. Doing that prevents welds from oxidising when being welded and thus preserve chemical and mechanical properties.
