In this work, low-carbon steel AISI-SAE grade 1010 with copper grade CDA 101 was joined by friction stir welding (FSW) using a tapered pin profiled tool. The rotational speed of the tool is 900 rpm, a traverse rate of 30 mm/min, and an axial force of 5 kN were used to produce the joints. The microstructural analysis and mechanical properties of the weld joints have been successfully examined. The optical microscopy, scanning electron microscopy, and X-ray diffraction (XRD) techniques were performed to examine the macropatterns and micropatterns of the welded joints. The tensile and hardness test was performed to evaluate the mechanical behaviours of the FSW joints. The fine ferrite grain features with uniform size were obtained in the microstructure of the nugget zone (stir zone). It is purely influenced by the alternating dynamic rearrangement (recrystallization) mechanism. High hardness was identified in the stir zone, even as the slightest stability was established in the heat-affected zone. The tensile investigation proposed that all the joints explored just lesser unbending nature than the parent material. The tensile strength of 181.5 MPa, the hardness of 144 VHN, and elongation of 14.03% were observed for the welded samples. The better properties for the weld joints were attained at 900 rpm spindle speed and tool traverse speed of 30 mm/min. The FSW is an attractive material joining process for both similar and dissimilar materials compared to other conventional types of joining processes, such as aerospace, marine engineering, shipbuilding, and industrial sector applications.

“…Since the diffusion coefficient of Cr is much lower than C, there is no visible Cr content at the weld interface. Carbon was effective in the element diffusion process [19]. Broken surface elemental mapping analysis of joint interface of S3 sample is given in Fig.…”

In this study, continuous drive friction welding process is selected for joint dissimilar high chromium white cast iron and mild carbon steeel. The microstructure, presence and diffusion of elements, deformation in interface of weld metal were analyzed by scanning electron microscopy (SEM), optical microscopy (OM), energy dispersive spectroscopy (EDS), elemental mapping and X-Ray diffraction (XRD). Elemental analysis was applied to the fractured surface after the tensile test. The rotational speed from the friction welding process parameters had a significant impact on the quality of the welded joint. Due to element diffusion at the weld interface, carbides consisting of Cr7C3 and Cr23C6 were occurred. Carbon, which is the dominant element of the diffusion process, was decisive in the emergence of the carbide layer.
