E309L-16 Welding Rod (CHS062)
E309L-16 welding rod is suitable for welding structures fabricated by similar extra-low carbon stainless steels or for welding structures fabricated by ply steels and dissimilar steels. Also it could be used for surfacing lining intermediate layer of pressure vessels of nuclear reactor. The weld metal has good resistance to weld intercrystalline corrosion although there is no niobium and titanium.
Type of Covering: Lime-titania
Welding Position: F, H, HF, OH, V
Type of Current: DCEP or AC
- The rod should be baked at 300℃-350℃ for 1 hour before use.
- The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
- Smaller current and short arc are recommended in welding and weave beads no wider than 2.5 times of the diameter of the core rod is better.
