The demand of modern industry always requiresgreater competence and production quality
The requests for improvement in thequality of the manufacture of pipes orcontainers have increased exponentiallyin recent years, particularly in thechemical-pharmaceutical, scientific andfood sectors.
Every single material requires a
specific root protection gas.
Carbon steel, stainless steel, Duplex and Superduplex,
aluminium, and many other gases have different
metallurgical characteristics and reactivity to air.
The choice of the inert gas or reducing mixture, must be
made by following the compatibility criterion of the
material to weld and critical aspects of the atmosphere
generated inside the tank - tube to weld.
There are on the market, devices and analysers allowing
a correct and safe use of the reducing gas, thus avoiding
waste of gas or incorrect use, which voids the operating
