diamondspark S 700 HP is a seamless flux-cored wire for submerged arc welding, low alloyed and high strength, with a yield strength above 690 MPa and a low level of diffusible hydrogen, at most 4 ml per 100 g.
The wire works as a set with a matched flux, which decides the mechanical properties of the weld. Its seamless sheath protects the core against moisture even after long storage, the deposition rate shortens the filling of heavier grooves, and it goes into machine building, crane structures and commercial vehicles.
- Classification EN ISO: 26304-A, TZ3Ni2.5CrMo
- AWS classification: A5.23 / SFA-5.23, ECF5
- Shielding: flux matched to the wire, no shielding gas
Keep the heat input within the range the steel maker specifies, going above it lowers the strength of the joint. 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.
