diamondspark S NiCu1 is a seamless flux-cored wire for submerged arc welding, low alloyed and high strength, alloyed with copper and nickel for weather resistant steels.
Submerged arc welding gives a very high deposition rate on long, repeatable welds. The seamless sheath protects the core against moisture even after long storage, and the wire goes onto working machines, booms and cranes, welded on mechanised stations.
- Shielding: flux matched to the wire, no shielding gas
Keep the hydrogen level low: dry consumables, a clean groove and preheating on heavier sections. Match the flux to this wire and check how dry it is, drying the flux decides the hydrogen level in the weld. Keep an even flux layer over the arc, too thin a layer exposes the arc and too thick a one spoils the bead shape. Keep the heat input within the range the steel maker specifies, going above it lowers the strength of the joint.
