Cladding
With Over 30 Years of Cladding Experience.
Cladding, commonly known as weld inlay and overlay, is the process of depositing a material on the surface of another for enhanced material properties (primarily corrosion resistance). Cladding/Overlay is consists of melting high-performance alloys onto the surface of a base material, typically carbon steel. Adding one or several layers of this alloy to the base material is a cost-effective way of improving material properties, typically corrosion resistance or other mechanical properties.
The most prolific alloy used in the Oil & Gas industry is NiCroMo-3 or Inconel 625. We are able to clad a wide variety of corrosion resistant alloys from stainless grades like 316L to combination corrosion/erosion resistant alloys like Cobalt/Stellite-6.

Inlay Cladding
Inlay cladding has several advantages over selective plating. The process allows the use of virtually any wrought alloy, ensuring a highly consistent composition, and allowing many alloys to be used which ordinarily could not be plated. Through careful selection of materials, a surface can be attained that is denser, harder and more wear resistant than a plated surface.
Overlay Cladding
Overlay cladding is a process by which dissimilar layers of metals are bonded together into a composite material. This is a metallurgical process which uses no adhesives or filler materials. It is accomplished through the use of extreme pressure and, in some cases, heat. The process can produce what are commonly called single clad (two layers), double clad (three layers), and in some specific instances as many as seven layers. All Clad Metal Specialties overlays are custom made to your exact specifications. Our processes have the capability of bonding such dissimilar metals as nickel to gold, tin to copper, silver to aluminum. The combinations available, limited only by the designer’s imagination, can be manufactured in widths from .100″ to 5″, and thicknesses from .001″ to .125″.
Spooltech provides cladding for a variety of use cases for our on-shore, offshore, subsea, chemical, and nuclear customers. While Spooltech provides best in class cladding services, we also perform this service with various other welding processes and to multiple industry specifications.
