Particular working of metal is used to face hard material on worn pieces or pieces that will become easily worn (hard facing welding); this hard facing operation is also referred to as loading (depositing the metal).
In wearing pieces whose surface hardness is of prime importance, such hardness is obtained by hard facing the metal.
The metal is firmly tempered and made rigid.
There are various types of applications.
Very hard facings resistant to abrasive wear: cam shaft supports, cutting tools, extrusion screws, lamination cylinders, pivots, glass moulds.
Hard facings resistant to corrosion and heat: discharge valves, plastic material extruders, hot cutting tools, guide blades for reaction engines (turbines etc..).
Ultra-hard facings resistant to severe abrasion: mixing blades, asphalt lifts, forming segments and production chains for hollow brick formation, stripping points, cutting tools.
Medium hardness facings and welding: glassware moulds, skids and guides for machine tools, valve and pump compartments.
Processing facings: cardan joints, couplings, cams, gears and screws.
Processing hard facings: tools for moulds, glass moulds, oil press hammers, pump rotors, rollers, jacks and stops.
