AWS/ASME A 5.9 ER 316L
EN 12072: W 19 123 L
| FEATURES & APPLICATIONS |
6316 Tig rod is an extremely low carbon stainless steel Alloy with molybdenum 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.
- A special 316L Tig alloy coated with our unique Vari-Flow fluxing system.
- A very special Tig wire that eliminates the expense and wasted time associated with purging pipes with inert backing gasses.
- Easy to handle 18 inch (450mm) length works in multiple positions without having to bend the wire.
- Can be ordered in grade 308L as item number 6308.
- Any other grade of stainless can be manufactured in 100 pound (45kg) per diameter minimum quantities.

| Welding Current & Instructions |
Recommended Current: DC Straight (-)
Recommended Amperage Settings:
| Diameter (mm) | 3/32 (2.5) | 1/8 (3.25) |
| Minimum Amperage | 60 | 80 |
| Maximum Amperage | 100 | 120 |
Welding Techniques: Clean weld surface carefully to remove all scale and corrosion. Sections over 3mm should be beveled to permit complete penetration. Clean joint surface using a stainless steel brush. Use DC – (straight polarity), 2% thoriated tungsten electrode.
