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.

“…The quality and productivity improved if the weld overlay process was executed automatically. Furthermore, the better features of the surface finish are achieved with the smallest dilution rate of the added material [15]. The automation of weld overlaying for huge dimensions and complex geometry of the tube walls constitute a major challenge, as shown in Figure 1.…”

Tube walls are an essential part of the thermal power plant boiler. During the operation of the boiler, the heating surface of the tube walls are exposed to furnace particles, intense heat, and chemical components resulting from the combustion reaction. These cause corrosion and wear, which permanently collapse the tubes, and affect the reliability and performance of the boiler. Therefore, a protection layer of heat and corrosion-resistant material is typically welded on the surface of the tube walls. In this study, a dedicated weld overlay automatic system is proposed. The downward welding technique with the pulse gas metal arc welding (GMAW) process is used to accomplish the proposed approach. The system generates and plans beads sequence based on the analysis of the tube walls geometry. The inverse kinematic theory was used to calculate the coordinates and transformations of the welding torch. Then, a mathematical model for the welding torch trajectory was established. A SIMOTION controller was adapted for motion control. A weld-tracking system based on the adaptive neuro-fuzzy inference system (ANFIS) was used to solve the welding distortion and the assembly error. The experiment results show that the proposed design is efficient and reliable compared to previous methods. The degree of automation and the weld overlay quality of the boiler tube walls have been notably improved.
