Weld overlay (also known as cladding, hardfacing, or surfacing) offers several significant advantages over using solid alloy materials or other coating techniques, making it a widely adopted process in industries like oil & gas, power generation, mining, chemical processing, and heavy manufacturing.

Carbon steel can be clad with a variety of materials depending on the intended application. Some commonly used cladding materials for carbon steel include stainless steel, nickel alloys, copper alloys, and titanium. The choice of cladding material will depend on factors such as the desired corrosion resistance, mechanical properties, and cost. For example, stainless steel is often used to clad carbon steel in applications where corrosion resistance is important, while nickel alloys are commonly used in high-temperature environments. We can supply various caldding products, including pipe, fitting, flange and dished end. 

Overlay welding involves depositing a layer of weld material onto the surface of a base metal. This is typically done using a welding process such as TIG or MIG welding. The purpose of overlay welding is to improve the corrosion resistance or wear resistance of the base metal. This method is commonly used in applications such as oil and gas pipelines, where corrosion resistance is critical.

Explosive cladding, on the other hand, involves using explosives to bond two or more metals together. In this process, the two metals are placed in contact with each other and an explosive charge is detonated, causing the metals to bond together at high velocity. This method is often used to join dissimilar metals together, such as aluminum and steel, and can produce a metallurgical bond that is very strong.
