Abstract
TIG welding of thin sheet made of austenitic stainless steel is the most widely spread welding process. The shielding gas used can be Ar or mixtures of Ar+5-10%H2 and He. As root shield, Ar, N2+H2(5-20%) mixture or pure nitrogen are used. In literature, there is no indication of the use of pure nitrogen as a shielding gas. The welding procedure using nitrogen as a shielding gas and a root shield would be the most low-priced of all the known procedures. Investigations would be conducted on electric-arc characteristics, a comparison made with other gases, an influence on weld microstructure, mechanical properties, penetration depth with the same welding parameters, penetration shape, and corrosion properties of welds. If steel contains a small content of nitrogen, it is characteristic that its pitting-corrosion resistance increases.
