GENERAL DESCRIPTION AND UNIQUE FEATURES
• The process involves surface cladding of well heads & valves for off-shore and oil related companies.
Depositing 2 or 3 layers of corrosive resistant materials such as Inconel 625 or Stellite.
• High deposition is achieved by the twin hot-wire cladding process with dilution levels as low as 5 % in a
single pass.
• Bead geometry 8 mm wide & 5 mm din depth. Weld deposit in excess of 4 kg/hour.
