Fusion hard facing is a process by which weld materials, with superior properties than the substrate, are applied to the substrate. Often, two layers total 3 - 6 mm (1/4 - 1/2 in) thick are applied to reduce the surface hardness dilution of the relatively low-cost steel substrates in the expansive cobalt-base alloys. Hard facing processes are very useful for improving wear and corrosion resistance to selected areas of machinery, such as cutting edges of earth-moving machinery.

This can be carried out very successfully using flux cored self shielding wire or stick welding process.

Case Study,

A Crusher Rotor has a typical life of 1500hrs & costs 24K.
we resurfaced the rotor at 800Hrs at a cost of 3K, The rotor has reached 1500Hrs, and wear is less than when resurfaced.
For a typical life span of 6000Hrs for the crusher, 4 rotors totalling 96K would be required, if resurfacing had been repeated a further 7 times the total cost would be 24K. A saving of over 70K.

We have successfully used this process on applications from Brick Making Dies through to excavators and crushing machines.
