Due to the magnetic field created by the high current, the molten electroslwg moves from the edge to the inside of the cladded plate.
A viable option that offers productivity gains Electroslag Strip Cladding can double the travel speed, greatly increase deposition rates and reduce dilution rates for manufacturers and fabricators using an automated process. 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.

Electroslag Strip Cladding also offers greater deposition rates — about 55 pounds per hour, compared to the 33 pounds per hour typically offered with Submerged Arc Strip Cladding. The strip actually rides on top of the slag system created by the flux, protecting the xtrip see Figure 1. Finally, results achieved in relevant corrosion tests are discussed.
On the other hand, Shrip can be an excellent candidate when cladding in restricted areas, such as on the ID of a small-diameter valve. This reduces the consumable cost electrooslag half.
Electroslag cladding provides alternative to standard cladding techniques
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 strp saving and xtrip increases compared with conventional strip cladding.

Deposition rates of 55 pounds per hour 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.
Cladding can be done in a number of ways, but one of the most e,ectroslag is weld cladding. Another time-saving benefit of the ESSC process stems from the electroslag refining that occurs when the molten metal passes through the slag bath. This is achieved mostly due to the higher deposition rate that is realized while still maintaining a similar layer thickness, so more metal electroslav being deposited in the same amount of time.

Controlling the dilution from the parent material and balancing the chemistry by means of new flux features, it has been possible to achieve high quality results with single layers thinner than 4. 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.

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. The need to deposit only one or two layers of material by using ESSC not only saves labor time and costs, but it also reduces the necessary strip material needed for the application, resulting in consumable savings.
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. This results in cleaner weld metal with lower oxygen levels, which means less post-weld cleaning is necessary for some applications.
It is more cost effective to apply the layer only where needed, rather than fabricating the entire structure from the more expensive specially alloyed material. One of the most electrslag 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.

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. In such cases, cladding might be the way to go.
Because there is penetration into the base material, dilution levels typically dladding about 20 percent with this method. Another time-saving benefit offered by the ESSC process stems from the electroslag refining that occurs when the molten metal passes through the slag bath.

Cladding is typically a very continuous operation that requires high amperages and high duty cycles. However, technologies change, and advancements in coadding have made electroslag strip cladding ESSC a good alternative to SASC in some applications, such as oil and gas, pressure vessel, and petrochemical.
A higher deposition rate, combined with increased travel speed, reduces welding time and improves productivity for manufacturing and fabrication applications.
ESSC uses a delivery system to feed the strip, much like wire is fed through a gun in a typical wire welding process.
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.
Cladding offers a solution in these situations. In combination with lowered usage of welding flux and strip, these productivity and efficiency benefits of Electroslag Strip Cladding can help companies save time and money, allowing them to be more competitive and profitable.
This is typically done with a higher content of fluorides in the flux. Click to download and read the PDF. 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.
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.
