Electroslag Strip Cladding Offers Productivity and Cost Benefits

Cladding is a fundamental process to the manufacturing and fabrication industries and is used across many applications, including petrochemical, oil and gas, pressure vessel and boiler making. The strip actually rides wtrip top of the slag system created by the flux, protecting the weld. An unknown error occurred.

Consider return on investment The Electroslag Strip Cladding process may require investing in more equipment than SASC, a factor that may make some companies hesitant to consider the process.

The process of cladding involves putting a new layer on top of an existing work piece — sometimes to repair items such as nozzles, ball valves, mill rolls and shafts — or to improve the wear resistance or corrosion properties of the piece.

Since ESSC is not an arc process, heating takes place in the conductive flux, and the resulting heating effect melts the strip and base material into the liquid slag, which is then transferred into molten metal that is deposited onto the base material.

High-quality electroslag strip cladding for alloy

Cladding is typically a very continuous operation that requires electros,ag amperages and high duty cycles. Because the weld pool penetrates the base material, dilution levels typically are about 20 percent.

They have been used for decades. Using magnetic steering connected to the welding head can help control this effect. The process is often used when there is a need to use mild or low-alloy steel for the main structure with a specially alloyed material applied to a certain portion of the work piece to accommodate necessary properties.


It is more cost effective to apply the layer only claeding needed, rather than fabricating the entire structure from the more expensive specially alloyed material. Choosing equipment, accessories and consumables designed for Electroslag Strip Cladding can help manufacturers find success with the ESSC process.

The flux for each process looks similar, but the ESSC flux is specifically formulated to work with that striip. It is usually more cost-effective to apply the specialty layer only where needed rather than fabricate the entire structure from the more expensive alloy.

Strip Cladding processes are better suited for applications where a high deposition rate is desirable and where the part will accommodate this higher rate of deposition.

Today, it remains the only North American publication devoted to this industry and it has become the most trusted source of information for tube and pipe professionals. Finally, results achieved in relevant corrosion tests are discussed.

Chemical composition and mechanical properties obtained with the newly developed solutions are also presented. Electroslag Strip Cladding offers some advantages when compared to its SASC counterpart, including a reduced dilution rate of base material into the weld — typically about 10 percent for ESSC compared to 20 percent for SASC — along with greater deposition rates, improved travel speeds and lower flux consumption.

Electroslag cladding provides alternative to standard cladding techniques

Cladding is typically a continuous operation that requires high amperages and high duty cycles. That compares to the minimum of two passes needed to get the required overlay chemistry with Submerged Arc Strip Cladding. Electros,ag cladding processes are well-suited for applications that require strlp deposition rates.

One of the most interesting features of the electroslag strip cladding process ESSC is that it can achieve the desired chemical composition in only one layer for almost all alloys used in the process industry.

However, technology advancements, especially related electroslay consumables, have made the Electroslag Strip Cladding ESSC process a good alternative in some applications, such as oil and gas, pressure vessel and petrochemical — one that can save labor time and material costs and greatly increase the deposition rate. The heat melts the strip and base material into the liquid slag, which then is transferred into molten metal that is deposited onto the base material.

Another time-saving benefit of the ESSC process stems from the electroslag refining that occurs when the molten metal passes through the slag bath. All welding processes can be used for Cladding, but due to constraints in the physical requirements, some welding processes are better suited for Cladding than others.

Because the dilution rate with ESSC is much less, the process can often be completed by applying one layer of material using a flux for standard travel speed — whereas two layers are typically required when using a high-speed ESSC flux. Because there is penetration into the base material, dilution levels typically are about 20 percent with this method.
