Electoslag 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. Electroslag Strip Electrosla 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.

This article gives an overview of the relevant specifications, followed by details on the applied welding conditions and the quantitative results achieved, which show the benefits in terms of material saving and clzdding increases compared with conventional strip cladding.
The entered e-mail addresses do not match. ESSC uses a delivery system to feed the strip, much like wire is fed through a gun in a typical wire welding process. The strip actually rides on top of the slag system created by the flux, protecting the weld. Strip cladding processes are well-suited for applications that require high deposition rates. 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.
All welding processes can be used for cladding, but constraints in the physical requirements make some welding processes better suited to the process than others.

Click to download and read the PDF. Strip Cladding has been around for decades, and historically, Submerged Arc Strip Cladding SASC has been the most commonly used process, offering deposition rates of about 33 pounds per hour.
Electroslag Strip Cladding Offers Productivity and Cost Benefits
For this alloy, new thin single layer solutions have been developed with the aim of reducing the overlay thickness in order to save material and improve productivity, while meeting the deposited metal industry requirements, which are very demanding in many cases.
Because the dilution rate with ESSC is low, the process strop can be completed by applying just one layer of material at a standard travel speed, whereas two layers typically are required when using a high-speed ESSC flux.
Because there is penetration strop the base material, dilution levels typically are about 20 percent with this method. This results in cleaner weld metal with lower oxygen levels, which means less post-weld cleaning is necessary for some applications. Another difference between Submerged Arc Strip Cladding and Electroslag Strip Cladding is that the flux is delivered in front of the weld in ESSC, while in SASC, the flux is delivered claddding both the front and behind the weld, to shield the arc from atmospheric contamination.
Due to the magnetic field created by the high current, the molten metal moves from the edge to the inside of the cladded plate. This is achieved mostly due to the higher deposition rate that is realized while still maintaining a similar layer thickness, so more metal is being deposited in the same amount of time. 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.

Cladding offers a solution in these situations. Controlling the dilution from the parent material and balancing the chemistry by means of new flux features, stirp has been possible to achieve high quality results with single layers thinner than 4.
Another time-saving benefit of the ESSC process stems from the electroslag refining that occurs when the molten metal passes through the slag bath. Please try again later. Because the weld pool penetrates the base material, dilution levels typically are about 20 percent. Deposition rates of claddkng pounds per hour Because the dilution rate with ESSC is much less, the process can often be completed by applying one layer of material claddlng a flux for standard travel speed — whereas two layers are typically required when using a high-speed ESSC flux.
Cladding can be done in a number of ways, but one of the most flexible is weld cladding.
On the other hand, GTAW can be an excellent candidate when cladding in restricted areas, such as electrosag the ID of a small-diameter valve. An unknown error occurred. This is typically done with a higher content of fluorides in the flux. The arc in SASC runs along the entire strip width. However, technologies change, and advancements in consumables have made electroslag strip cladding ESSC a good alternative to SASC in some applications, such as oil and gas, pressure vessel, and electroelag.
In such cases, cladding might be the way to go. There are many types of Cladding, but one of the most flexible is Weld Cladding.
Choosing equipment, accessories and consumables designed for Electroslag Strip Fladding can help manufacturers find success with the ESSC process.
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. At least one newsletter must be selected. One of the most electrosag 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. Electrooslag can save time and material costs and increase the deposition rate.
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. The heat input of the two processes is comparable. In consumable selection for ESSC, the strip width needed for the application is determined by the size and shape of the components to be surfaced.
One of the most commonly used processes, submerged arc strip cladding SASCalso is one of the most productive, offering deposition rates of about 33 lbs. You can manage your subscription s by signing into your account. All fields are required. Cladding is typically a continuous operation that requires high amperages and high duty cycles.
The strip actually rides on top of the slag system created by the flux, protecting the weld see Figure 1. Using magnetic steering connected to the welding head can help control this effect. This results in cleaner weld metal with lower oxygen levels, which means less postweld cleaning is necessary for some applications.
