Lincoln LNT 347Si welding rods, type ER347Si / W 19 9 Nb Si, contain niobium, which reduces the risk of intergranular corrosion by inhibiting the formation of chromium carbides. This alloy is resistant to corrosion in contact with liquids up to 400 °C. The increased silicon content affects the fluidity of the weld pool and facilitates flow, which translates into an even, well-shaped weld. The main applications of LNT 347Si rods are in the process industry and in the welding of stainless steel, especially where high temperatures occur. The welding process is carried out in an atmosphere of neutral argon gas (100% Ar).
