Recommended TIG Welding Parameters – DCEN (DC-) * Shielding gas use 100% Argon or Argon/Helium for greater penetration and higher speeds * Tungsten use 2% Thoriated, 2% Ceriated, 2% or 1.5% Lanthanated or Rare Earth For welding 18% chromium – 12% nickel – 2½% molybdenum austenitic stainless steels such as 316 and 317 but with a low ferrite (i.e. FN2) it can also be used for welding 304/304L to 316/316L stainless steels in cryogenic service at temperatures down to -452 °FThe maximum carbon content of less than 0.03% preserves the intergranular corrosion resistant properties of the weld deposit and weld zone, yielding x-ray quality weldsThe 2½% molybdenum content of 316L gives the weld deposit excellent corrosion resistance at elevated temperatures against “pitting” that may be caused by sulfuric, phosphoric and acetic acidsCommon applications include equipment that manufacturers rayon, dye, paper, ink, rubber, bleach, photographic chemicals and on the sealing faces of valves and fittings for acid, gas, water and steam equipmentAvailable Sizes: 0.045", 1/16", 3/32", & 1/8" - The maximum carbon content of less than 0.03% preserves the intergranular corrosion resistant properties of the weld deposit and weld zone yielding x-ray - Available Packages: 1 Lb, 2 Lb, 10 Lb & 11Lb - Choose from the menu.
