What’s the difference between cladding and weld overlay?
In the world of industrial surface engineering, the terms cladding and weld overlay are often used interchangeably. However, while they serve similar purposes—enhancing the surface properties of a base material—they differ in process, application, and technique. For engineers and procurement specialists looking for the right solution in pipeline and pipe fitting projects, understanding the difference between cladding and weld overlay is crucial.

What is cladding?
Cladding is a general term that refers to applying a protective or functional layer onto a base metal. Cladding can be achieved through a variety of methods, such as thermal spraying, Hot Dip Coating,etc.Weld overlay is just a specific method included in Cladding.
The main goal of cladding is to improve corrosion resistance, wear resistance, or high-temperature performance without using expensive materials for the entire component. In pipeline systems, cladding is widely used on the inner lining or surface of carbon steel pipes to increase their wear resistance and corrosion resistance at a lower cost.

What is weld overlay?
Weld overlay, sometimes referred to as weld cladding, is a specific form of cladding that uses welding processes to apply the protective layer. These welding techniques include:
- GTAW (TIG)
- GMAW (MIG)
- SMAW (Manual Stick Welding)
- Submerged Arc Welding (SAW)
- Plasma Transferred Arc (PTA) and so on.
Unlike other cladding methods, weld overlay melts and fuses the filler metal with the substrate, creating a metallurgical bond. This is particularly beneficial for critical components like pipe fittings, valves, elbows, reducers, and tees, where mechanical strength and corrosion resistance are both essential.
