Cladding, also known as weld inlay or overlay, is the process of depositing a material on the surface of another for enhanced material properties (primarily corrosion resistance). While C&J specializes in GTAW-P-HW cladding, we also perform cladding using many other welding processes. The most common material for Oil & Gas cladding is nickel alloy 625, but with developing technology and advancements in materials we are discovering new alloys that may result in longer life for your project.

C&J maintains more than 200 welding procedures for cladding.


  • 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
