diamondspark S 900 HP is a seamless flux-cored wire for submerged arc welding, low alloyed and high strength, with a yield strength above 900 MPa and a low level of diffusible hydrogen, at most 4 ml per 100 g.
Submerged arc welding gives a very high deposition rate on long, repeatable welds. The seamless construction limits moisture pick-up in the core, the deposition rate shortens the filling of heavier grooves, and the wire goes into mobile equipment, machine frames and cranes.
- Classification EN ISO: 26304-A, TZ3Ni2.5CrMoMn1.9
- AWS classification: A5.23 / SFA-5.23, ECG
- Shielding: flux matched to the wire, no shielding gas
Do not exceed the permitted interpass temperature, an overheated heat affected zone loses its toughness. 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.
