APPLICATIONS :
STANLEY 709 F, TIG rod is an extremely low carbon stainless steel Alloy with extra high molybdenum content added to provide superior corrosion resistance. It is especially well suited for welding stainless steel pipe wherever a backing ring or a purge gas is required in order to provide impurity free weldments. This is necessary during stainless steel pipe welding in the chemical and petro-chemical industries.
MICROSTRUCTURE :
Austenite with 3 – 9 % ferrite. Tipical ferrite number is 6.
RECOMMENDED CURRENT :
DC Straight (-)
WELDING POSITIONS :
Flat, Horizontal, Vertical up
WELDING TECHNIQUES :
Clean weld surface carefully to remove all scale and corrosion. Sections over 3 mm should be beveled to permit complete penetration. Clean joint surface using a stainless steel brush. Use DC - ( straight polarity ), 20 % thoriated tungsten electrode. |
