Levin et al. deposited several weld overlays over carbon steel using PTA welding and found that the steady state erosion rates for several weld overlay coatings such as Inconel-625 and SS 316 L A comparative study on microstructure and properties of May 05, 2015 · The current study investigates the overlays deposited by laser beam (LB) and gas tungsten arc (GTA) cladding with Inconel 52M filler wire in nuclear power plants. The effects of the deposition methods on the cross section profile, microstructures, and mechanical properties of both overlays are studied using optical microscope, scanning electron microscope (SEM), tensile and
Weld overlay with Ni-based superalloys is an important option for industrial applications. New alloys have been developed to assure desirable characteristics such as corrosion resistance. The Inconel 686 superalloy was developed with a higher Cr and Mo content in order to improve its resistance to corrosion. Cladding Services C&J CladdingCladding, also known as weld inlay or overlay, is the process of depositing a material on the surface of another for enhanced material properties (primarily corrosion resistance). While C&J specializes in GTAW-P-HW cladding, we also perform cladding using many other welding processes. The most common material for Oil & Gas cladding is nickel
Mar 13, 2019 · The low dilution cladding process, Cold metal arc transfer (CMT) is an modified version of conventional GMAW welding process with the advantage of controlled heat input was carried out for studying the microstructural, corrosion and wear behaviour of Inconel 625 superalloy. The CMT cladding, in addition can be used as a repair method for any Corrosion protection of low-cost carbon steel with SS Jan 16, 2019 · The dissimilar weld overlay coatings of components can lead to corrosion. In the present work, two different weld overlay layers (SS-309Mo and Inconel-625) are deposited on IS2062 grade B carbon steel, in order to avoid distortions and improve corrosion resistance.
INCONEL® nickel-chromium alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength, excellent fabricability (including joining), and out-standing corrosion resistance. Service temperatures range from cryogenic to 1800°F (982°C). Composition is shown in Table 1.

The 13CrMo4-5 ferritic steel is commonly used in power plants, due to its favorable mechanical properties. According to EN10028-2, this steel can be used at temperatures up to 570 °C because of its creep behavior. The inefficient corrosion resistance limits the application of this steel to lower temperatures depending on the gas temperature and slag formation. In-situ Crack Repair by Laser CladdingOverlay cladding of the sealed cracks is required to improve pitting corrosion and resistance to stress corrosion cracking of the -repaired areas. crack Cladding trials were performed to determine the effect of cladding position, nozzle standoff and angle between work piece and laser beam on powder efficiency for overlay cladding.

In contrast, the heat input of the laser beam can be accurately adjusted. It has minimal side effects on the mechanical integrity of the component, and can either locally treat the damaged area or improve the surface properties for a specific part in the chain of manufacturing. The unique advantages of laser claWHITE PAPER COST-SAVING LASER CLADDED ALLOYS Laser cladding of Inconel 625 TCC is a gold-standard as it combines excellent wear resistance in both corrosive and high-temperature service conditions. This paper demonstrates that novel laser cladding blends can yield both direct cost saving (in the case of SS 55) and combine these with improved wear resistance and TCO (in the case of Impac-10X).
