Cladding & Weld Overlay provides protection against corrosion and wear for process and oil and gas pipeline equipment. Weld overlay can be applied to extend the service life of new parts, or refurbish parts that have corroded or worn surfaces.
Reliable integrated and advanced welding technologies provides effective welding solutions for :
Oil & Gas Industries
Sub-Sea Applications
Petrochemicals & Refineries

Types of Cladding Process :
Weld Overlay :
Weld Overlay is a fusion welding technique used to deposit weld metal on to component to achieve the desired dimensions or properties replacing lost material or providing a wear or corrosion resistance surface.
Explosion Bond :
Explosion bonding is a process of bonding two dissimilar materials with the help of pressure and heat produced by explosion. The explosive material is spread on the material to be cladded which is kept on top of the base material. On ignition of the explosive, resultant thrust bonds the clad plate on the base plate underneath. Various combination of clad plate and base plate thickness can be bonded, depending on the job requirements.
