SAFETY IN TIG WELDING-Radiation Energy Hazard

Radiant energy may cause injury to the welder in two areas, eye and the skin. Any personnel, whether the welder, inspection personnel or the helper, present within the immediate vicinity of a welding operation, should be adequately protected from the radiation, particularly the ultraviolet radiation produced by the welding arc. Generally the highest ultraviolet radiant energy intensities are produced when argon shielding gas is used and when aluminium or stainless steel is welded. For the protection of the eye, filter glasses of proper shade depending on the welding current should be used.

The recommended shades for different welding current as prescribed in national / international relevant safety standards and codes should be selected.
