Weld Cladding / Metal Overlay
Cladding is defined by the Welding Institute as ‘providing a corrosion or oxidation resistant surface on a less corrosion resistant material. For example; the deposition of a stainless steel or nickel-based layer on a carbon steel base. One advantage of this technique is cost saving arising when surfacing a relatively inexpensive metal, such as a carbon steel, with a more expensive but corrosion resistant layer of stainless steel.
Material and weight savings may be gained when a clad, high strength, quenched and tempered steel is used in a corrosive environment.
Weld cladding engineering of alloy steel with corrosion resistant alloys is a process widely used throughout the oil & gas industry.
This weld cladding process provides a cost effective surface treatment for components used in highly aggressive services where highly corrosive/erosive or extreme “wear” mechanisms prevail.
CTL has a partnership with Glacier Energy Services & ARC Energy to provide a specialised “turnkey” overlay cladding and machining service to a wide variety of clients.
A wide range of qualified procedures are currently in place, for the overlay cladding of low alloy/carbon steels with Stainless Steel, Inconel, Monel, Stellite, Hastelloy.
