HARDFACING ELECTRODES / WIRES FOR WEAR PROTECTION



Products for tool and die repair

 


Protection of Earthmoving /mining equipment

 

Valuable equipment is subject to extreme wear by abrasion ,corrosion, erosion, friction or  impact causing industries billions in terms of lost production and equipment failure.

ADVANTAGES OF HARDFACING

  • Prolongs the life of parts and increases efficiency
  • Reduces equipment downtime as it keeps equipment longer working.
  • Productivity and profitability is increased
  • Reduction of spare parts  inventory. Resurfaced parts will help to reduce stocks of new parts normally required for emergency and general replacement   
  • Reduced power (energy) consumption .
  • Hard surfaced parts remain in better shape  for a longer time resulting in saving of power consumption
