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.

The strip actually rides on top of the slag system created by the flux, protecting the weld.

Designed by Multidimensions and Powered by YMarketing. This results in cleaner weld metal with lower oxygen levels, elfctroslag means less post-weld cleaning is necessary for some applications.

Cladding is typically a very continuous operation that requires high amperages and high duty cycles. 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.

One of the most interesting features of the electroslag strip cladding process ESSC is that it claddiny achieve the desired chemical composition in only one layer for almost all alloys used in the process industry. Related Companies Miller Electric Mfg.

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 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. 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.

Electroslag Strip Cladding can double the travel speed, greatly increase deposition rates and reduce dilution rates for manufacturers and fabricators using an automated process. 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.

Using magnetic steering connected to the welding head can help control this effect.

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.

Strip cladding processes are well-suited for applications that require high deposition rates.

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

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.

Electroslag Strip Cladding offers some advantages when compared to claddingg 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.

With Submerged Arc Strip Cladding, an arc runs along the width of the strip, depositing weld metal on the base material. You can manage etrip subscription s by signing into your account. Because there is penetration into the base material, dilution levels typically are about 20 percent with this method.

This reduces the consumable cost by half. 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. 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 is typically done with a higher content of fluorides in the flux.

Electroslag cladding provides alternative to standard cladding techniques

In such cases, cladding might be the way to go. All fields are required. Because the dilution rate with ESSC is much less, the process can often be completed by applying one layer of material using electrislag flux for standard travel speed — whereas two layers are typically required when using a high-speed ESSC flux.

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. Another time-saving benefit of the ESSC process stems from the electroslag refining that occurs when the molten metal passes through the slag bath. 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.

Sgrip arc in SASC runs along the entire strip width. To activate your FREE subscription today, simply select which newsletter s you would like to receive and complete the form below. ESSC has a high deposition rate, in some cases reaching 55 lbs. ESSC uses a delivery system to feed the strip, much like wire is fed through a gun in a typical wire welding process. 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.

This results in cleaner weld metal with lower oxygen levels, which means less postweld cleaning is necessary for some applications.

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. Cladding offers a solution in these situations.
