WEARcore Dur 400-S is a submerged arc cored wire for rebuilding and hard surfacing carbon steel parts subject to adhesive wear with impact.
Submerged arc welding gives a very high deposition rate on long, repeatable welds. The wire is used on mechanised stations, on butt welds in plate and circumferential welds on tanks. Previously sold as SK 242-S.
- Classification EN ISO: 14700 T Fe1
- AWS classification: 8555 UP 1-GF-40-P
- Shielding: flux matched to the wire, no shielding gas
- Hardness of deposit: 40 HRC Record SA
Check how many layers you need to reach the target hardness, the first layer always mixes with the base material. Keep an even flux layer over the arc, too thin a layer exposes the arc and too thick a one spoils the bead shape. Watch the wire stick-out and the position of the head against the weld centre line, under a flux you cannot see the pool and a mistake shows only after the slag is chipped off.
