“…The results showed in Table 4, confirm that all requirements are achieved, as well as they do not show significant differences for the conditions considered in this work. Basically, this behavior can be attributed to the association of low dilution ( < 10%), and Fe content inferior to 5% at 3.0 mm from fusion line ( Table 7 and Figure 10), which is the recommended minimum thickness required for weld overlay applied in corrosive hydrocarbon systems [7,8,15,18,46,61,62]. In addition, these results are in accordance to other works [17,46,60,63], which states that satisfactory corrosion results are obtained when welding parameters and dilution are controlled.…”

“…However, the high cost of superalloys limits their application from an economic point of view [1,4,5,7,8]. Consequently, in order to provide a cost-effective solution for this engineering challenge, cladding or overlays with nickel-based alloys enters more and more into the focus of engineers [1,4].…”

“…In comparison with other methods, weld overlays are characterized by strong metallurgical bonding with the base material, due to the interpenetration of the deposited and supporting materials; it is also relatively easy to produce an overlay free from pores or other defects [9]. In this respect, there are several initiatives in order to develop overlays and/or cladding procedures using nickel-based superalloys as an alternative for manufacturing equipment whose external or internal surfaces require specific properties [5,[7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Usually, weld overlays are deposited by gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) processes [3,4,7,10,11,14,[17][18][19][20][21][22]. GTAW is very often used for cladding of critical parts especially for offshore subsea equipment due to its very high quality welds, while GMAW is the most applied welding process in Europe, United States of America and Japan due to its higher deposition rate [4].…”

Nickel-based weld overlays (cladding) are commonly used in oil & gas industry to extend the life of equipment under corrosive environment, as it improves the corrosion resistance without a significant increase in the manufacturing cost, when compared to a full nickel-based alloy equipment. Although there are extensive literature involving overlays applied by SMAW, GMAW or GTAW processes, works about the use of FCAW process are limited. Consequently, an investigation of the performance of the overlays deposited by this process, which provides a higher productivity in comparison to the processes usually used, can be an interesting option for this application. The present work evaluates the mechanical and microstructural properties of the nickel-based superalloy 625 weld overlay deposited on a ASTM A516 Grade 70 carbon steel plate by the flux cored arc welding process (FCAW), both in as welded and heat treated conditions. Bending and microhardness tests were performed in order to verify possible effects of welding thermal cycles on the mechanical properties. The microstructure was evaluated through both optical (OM) and scanning electron microscopy (SEM), with the use of electron backscatter diffraction (EBSD) technique. Corrosion tests were conducted on samples removed from the top layer of the weld overlay according to ASTM G 48 Method A. All results obtained with this welding process, in both as welded and heat treated samples, were considered satisfactory.

“…It is simple and easy-to-work but enough care should be taken to control the weld chemistry so that Fe content should be restricted upto 5%. Same principal was adopted successfully for GMAW cladding using Inconel 625 electrode wire (Elango and Balaguru, 2015).…”

Cladding is a popular surfacing technique in which a thick material layer covers a relatively low cost structural material to enhance its mechanical properties as well as corrosion resistance properties to increase service life. Among different cladding techniques, an overview on cladding done by Gas Metal Arc Welding (GMAW) is included in this paper. Different special techniques used in GMAW for producing clad parts; their characteristics, microstructure and corrosion resistance properties are discussed. Influence of process parameters on microstructure and corrosion resistance of GMAW clad parts is broadly reviewed. Newer techniques being explored and used regarding GMAW cladding along with the future scope of work are also indicated in this paper. At the end, it can be stated that GMAW is one of the most effective processes for producing clad parts.
