(Manoj Singh) #2

The fabrication is done by using TIG (Tungsten Inert Gas) orbital welding machine with a closed head in an inert atmosphere of argon gas to give crevice free welds with the concavity and convexity of the weld well within permissible limits. Grade 1 - 99.995% purity Argon gas should be used.Orbital welding is done for fabrication of pw/ wfi pipe distribution.
