ABSTRACT:
A screw flight element of a mechanical screw press for expressing liquids from fibrous material such as may be found in rendering operations and a method of remanufacture thereof and the product produced by the method. The helical flight section is one of several having different pitches used in such screw presses and is equipped with carbide elements spaced at strategic points along the periphery of the helical section and further surrounded with plasma arch welded cladding, thereby providing wear and shear points which are harder than the surrounding cladding which is in turn harder than the base material.
