Cladding can be done in a number of ways, but one of the most flexible is weld cladding. 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.
All fields are required. A higher deposition rate, combined with increased travel speed, reduces welding time and improves productivity for manufacturing and electrosllag applications. The need to deposit only one or two layers stripp 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.
An unknown error occurred.
Because the weld pool penetrates the base material, dilution levels typically are about 20 percent. 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. 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. 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.
With Submerged Arc Strip Cladding, an arc runs along the width of the strip, depositing weld metal on the base material. 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.
Cladding is typically a continuous operation that requires high amperages and high duty cycles.
Electroslag Strip Cladding Offers Productivity and Cost Benefits
This results in cleaner weld metal with lower oxygen levels, which means less postweld cleaning ellectroslag necessary for some applications. Consider return on investment The Electroslag Strip Cladding process etrip require investing in more equipment than SASC, a factor that may make some companies hesitant to consider the process.
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. Thank you for subscribing to our eNewsletters. ESSC has a high deposition rate, in some cases reaching 55 lbs.
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. Designed by Multidimensions and Powered by YMarketing. The entered e-mail addresses do not match. However, the productivity and efficiency gains that result 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.

The arc in SASC runs along the entire strip width. Electroslag Strip Electrooslag also offers greater deposition rates — about 55 pounds per hour, compared to the 33 pounds per hour typically offered with Submerged Arc Strip Cladding.
With Electroslag Strip Cladding, the strip is fed through a delivery system much like wire is fed during a typical wire welding process. They have been used for decades.
In such cases, cladding might be the way to go. Strip cladding processes are well-suited for applications that require high deposition rates. The strip electrodes are typically.
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 productivity increases compared with conventional strip cladding.
Home Article Tube and Pipe Fabrication Electroslag cladding provides alternative to standard cladding techniques. The heat input of the two processes are comparable. 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.
Because ESSC is not an arc process, heating takes place in the flux, which is conductive. 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.
ESSC can save time and material costs and increase the deposition rate. High-quality electroslag strip cladding for alloy Peter JeirudPieter Keultjes. Please try again later.

Elevtroslag 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. For example, gas tungsten arc welding GTAW is not well-suited to cladding large items or areas that need a large amount of buildup.
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. 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.
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.

High-quality electroslag strip cladding for alloy
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. There are many types of Cladding, but one of the most flexible is Weld Cladding. That compares to the minimum of two passes needed to get the required overlay chemistry with Submerged Arc Strip Cladding. Miller respects your privacy concerns.

Because the dilution rate with ESSC is low, the process often 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.
