Lime basic electrode for overlays on rails, rollers etc., machinable.

Hard surfacing of parts which need to be machined and which, in service, are subject to high compression stress and high impact. Can be applied in several layers. Used as buffer electrode when surfacing is carried out with electrodes showing higher abrasion resistance. Examples: buffer layer-rebuilding of worn parts such as rollers, wheels and guides encountered in the earth movig field.
