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.
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. Home Article Tube and Pipe Fabrication Electroslag cladding provides alternative to standard cladding techniques.
Click to download and read the PDF. The arc in SASC runs along the entire strip width. 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.
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. Cladding is typically a continuous operation that requires high amperages and high duty cycles. electrosslag
High-quality electroslag strip cladding for alloy
Because ESSC is sgrip an arc process, heating takes place in the flux, which is conductive. 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.

In consumable selection for ESSC, the strip width needed electroslaag the application is determined by the size and shape of the components to be surfaced. Because there is penetration into the base material, dilution levels typically are about 20 percent with this method. 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.
Electroslag cladding provides alternative to standard cladding techniques
This article gives an overview of the relevant specifications, followed by details on the electrosslag welding conditions and the quantitative results achieved, which show the benefits in terms of material saving and productivity increases compared with conventional strip cladding.
The strip electrodes are typically. The entered e-mail addresses do not match.
Choosing equipment, accessories and consumables designed for Electroslag Strip Cladding can help manufacturers find success with the ESSC process. You May Also Like.
However, the productivity and efficiency gains that elecctroslag from the increased travel speeds and deposition rates, lower dilution rates and the use of less welding consumables mean the return on investment can be only a matter of weeks for some operations. All clasding processes can be used for cladding, but constraints in the physical requirements make some welding processes better suited to the process than others. This results in cleaner weld metal with lower oxygen levels, which means less postweld cleaning is necessary for some applications.
Since ESSC is not an arc process, heating takes place in the conductive shrip, 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. This results in cleaner weld metal with lower oxygen levels, which means less post-weld cleaning is necessary for some applications.
Cladding can be done in a number of ways, but one of the most flexible is weld cladding.
ESSC can save clafding and material costs and increase the deposition rate. Strip cladding processes are well-suited for applications that require high deposition rates. Cladding is typically a very continuous operation that requires high amperages and high duty cycles.
Designed by Multidimensions and Powered by YMarketing. The Electroslag Strip Cladding process may require investing in more equipment than Electrosalg, a factor that may make some companies hesitant to consider the process.
Cladding offers a solution in these situations.
Electroslag Strip Cladding Offers Productivity and Cost Benefits

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.
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. Because the dilution rate with ESSC is much less, the process can often be completed by applying one layer of material using a stri; for standard travel speed — whereas two layers are typically required when using a high-speed ESSC flux.
Finally, results achieved in relevant corrosion tests are discussed. Due to the magnetic field created by the high current, the molten metal moves from the edge to the inside of the cladded plate.
