WeldSkill Harda is a basic electrode for the hard surfacing of steel components subjected to wet or dry hard particle abrasion and low to moderate impact loading.
The air hardening, low alloy steel deposit of WeldSkill Harda remains crack free on most steels under normal welding conditions and is therefore recommended for hard surfacing components subject to flexing during service.
The basic flux coating gives excellent resistance to rust, mill scale, dirt and oil on the surface being hardfaced. Typical applications include the surfacing of agricultural points, shares and tynes, grader and dozer blades, conveyor screws and post hole augers etc.
