Cigweld Cobalarc 650-FC Hardfacing Wire

Cobalarc 650-FC is a tubular hard surfacing wire for surfacing components subjected to wet or dry hard particle abrasion and low to moderate impact loading. The air hardening martensitic steel weld deposit of Cobalarc 650-FC remains crack free on most steels under normal welding conditions and is therefore recommended for the surfacing of components subject to flexing during service. Typical applications include the surfacing of agricultural points, shares and tynes, sand dredge cutter heads, dredge rollers and tumblers, conveyor screws, bucket lips, etc. Can be used for vertical surfacing by depositing overlapping horizontal stringer passes. It is used for single and multi-run welding of all plate thicknesses.

• Can be combined with a wide range of solid wires and cored wires
• Suitable for all kinds of steels
• Combines good toughness values with excellent weldability.
