The arc in SASC runs along the entire strip width.
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.
Due to the magnetic field created by the high current, the molten metal moves from the edge to the inside of the cladded plate. Because the weld pool penetrates the base material, dilution levels typically are about 20 percent.
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. 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 typical travel speed offered by the ESSC process is double that of Submerged Arc Strip Cladding — 10 inches or more per minute compared to 5 inches per minute.

With Electroslag Strip Cladding, the strip is fed through a delivery system much like wire is fed during a typical wire welding process. ESSC can save time and material costs and increase the deposition rate. 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.
They have been used for decades. Choosing equipment, accessories and consumables designed for Electroslag Strip Cladding can help manufacturers find success with the ESSC process.
Electroslag Strip Cladding Offers Productivity and Cost Benefits

Cladding offers a solution in these situations. One of the most commonly used processes, submerged arc strip cladding SASCalso epectroslag one of the most productive, offering deposition rates of about 33 lbs. 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.
Electroslag cladding provides alternative to standard cladding techniques
Another time-saving claadding offered by the ESSC process stems from the electroslag electrolsag that occurs when the molten metal passes through the slag bath. However, technology advancements, especially related to 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.
You can manage your subscription s by signing into your account. 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.
Please try again later. It is usually stirp cost-effective to apply the specialty layer clxdding where needed rather than fabricate the entire structure from the more expensive alloy. 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. An unknown error occurred. However, technologies change, and advancements in consumables have made electroslag strip cladding ESSC a good alternative to SASC in some applications, such as elwctroslag and gas, pressure vessel, and petrochemical.
The process is often used when there electrosllag 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.
This results in cleaner weld metal with lower electroslg levels, which means less post-weld cleaning is necessary for some applications.
This is achieved cadding due to the higher deposition rate that is realized while still maintaining a similar layer strkp, so more metal is being deposited in the same amount of time. Using magnetic steering connected to the stril head can help control this effect. Finally, results achieved in relevant corrosion tests are discussed. Because there is penetration into the base material, dilution levels typically are about 20 percent with this method. At least one newsletter must be selected.

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.

A higher deposition rate, combined with increased travel speed, reduces welding time and improves productivity for manufacturing and fabrication 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 at both the front and behind the weld, to shield the arc from atmospheric contamination. Electroslga welding processes can be used for cladding, but constraints in the physical requirements make some welding processes better suited to the process than others.
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. However, the productivity and efficiency gains that result from the increased travel speeds and deposition rates, lower dilution rates, and reduced use of welding consumables mean the return on investment can be a few months.

This reduces the consumable cost by half. Cladding can be done in a number of ways, but one of the most flexible is weld cladding.
