Hardfacing

Hardfacing is the process of depositing a harder or tougher material on the surface of another for enhanced abrasion, erosion or impact resistance. Hardfacing is a difficult process to master due to the crack sensitive nature of many hardfacing materials. C&J Cladding has focused on process controls and extensive research and development to ensure the highest quality hardfacing. This process is used to extend the life of components in many industries such as Oil and Gas, Drilling Tools, Mining, and Petrochemical or Refining.

C&J maintains more than 15 welding procedures for hardfacing.

Hard Facing Processes

  • GTAW-P-HW (Gas Tungsten Arc Welding Pulsed Hot Wire)
  • GTAW (Gas Tungsten Arc Welding or TIG or Heli-Arc)
  • SAW (Submerged Arc Welding)
  • SMAW (Shielded Metal Arc Welding or STICK)
  • GMAW (Gas Metal Arc Welding)
  • PAW (Plasma Arc Welding)
  • PTAW (Plasma Transferred Arc Welding) Wire Feed
  • PTAW (Plasma Transferred Arc Welding) Powder Feed
  • Above processes utilize manual, semi-automatic, and mechanized systems
