Boiler Tube Weld Overlay
Vclad® CMT is a proprietary weld overlay process that combines the economics and strength of carbon or low alloy base tube material, with a NiCrMo weld overlay layer in a range of materials specifically to meet the demands of corrosion mitigation in a variety of combustion environments.
The system technology delivers an automated and controlled application of Cold Metal Transfer (CMT) weld overlay to standard base tube materials. Programmable automation and advanced welding system architecture, ensure repeatable quality, and a high integrity weld overlay, with ultra low weld chemistry dilution.
Vclad® CMT weld overlaid tube encompasses the full range of typical boiler tube sizes 38 mm – 76.1 mm, but with the enhanced capability for large diameters up to 220 mm diameter for header and collector bodies, and < 38 mm for specialist superheater applications.
Cladding as surface protection for pressure part components installed in energy from waste, biomass, fluidized bed, and fossil fired boilers is an industry benchmark where aggressive combustion conditions exist.
Materials within our range of experience include Alloy 625, 622, 686, and 59.
