Cladding is often used to improve the erosion and corrosion of resistance of surfaces, whereby weld overlays of metals with very different properties from substrate extend the serviceable life of metals.
Metallurgical bond between surface and substrate
Controlled arc environment
Semi –Automatic /Fully Automatic
Cladding:
Coating material bonded to a substrate via mechanical force
Clad & Base metal are not melted during fusion
Common for highly corrosive applications, eg. Reactors, Vessels
Features:
Higher production rates because of continuous processing
Less weld metals required
Automation provides for the ability to continuously make root and fill passes and higher productivity
More process consistency resulting in more consistency joints with improved weld strength , toughness and fewer repairs
Reduces human error factors and less physical stain on welders especially on long welding / cladding process
Higher quality & higher productivity, especially with long duration welds
Lower processing costs
Overlay:
Fusion of a coating to a substrate via a welding process
Applicable for essentially all corrosion and wear applications
Overlay “restoration “welds used during clad fabrication projects
