Shielding gases

 

    The most important reason to use a shielding gas is to prevent the molten metal from the

harmful effect of the air. Even small amounts of oxygen in the air will oxidise the

alloying elements and create slag inclusions. Nitrogen is solved in the hot melted mate-

rial but when it solidifies the solubility decreases and the evaporating gas will form

pores.

     Nitrogen can also be a cause of brittleness. The shielding gas also influences the

welding properties and has great importance for the penetration and weld bead geom-

etry.
