WEARcore Tool 44-S is a submerged arc cored wire with good resistance to metal to metal and low stress abrasive wear at high temperature. It is used on farm tools, crusher parts, conveyors, ploughshares and mining machinery.
The wire is used on mechanised stations, on butt welds in plate and circumferential welds on tanks, and it works as a set with a matched flux that decides the mechanical properties of the weld. Previously sold as SK 258 L-SA.
- Classification EN ISO: 14700 T Z Fe7
- AWS classification: 8555 UP 6-GF-45-GT
- Shielding: flux matched to the wire, no shielding gas
- Hardness of deposit: 44 HRC Record SA
Remove the fatigued and hardened surface layer before you build up, a deposit laid on worn material will flake off. 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. Expect a network of shrinkage cracks in hard overlays, it must not reach into the parent material.
