“…Hardness analysis also indicated that the fracture propagates through the heat affected zone (HAZ) along the copper base-metal. A similar hardness gradient along both the sides of the interfacial region was reported in some other works published [ 97 , 98 , 100 , 106 , 107 , 108 ]. This clearly indicates limited atomic mobility along both sides of the interfaces for FW procedure compared to other solid-state welding processes such as HIP and DB.…”

“…Researchers have explored friction welding (FW) to join the dissimilar metals, but limited their investigation to pipe joints [ 160 , 161 , 162 , 163 ]. FW has shown significant potential to join copper with stainless steel [ 105 , 106 , 107 , 108 ]. Joint integrity mainly depends upon the formation of intermetallic along the interfaces.…”

“…In turn, the scientific community should seek the minimal adverse effect of fusion on the joint as well as trying to reduce the heterogeneity in viscosity, miscibility, melting point, thermal conductivity, and thermal expansion. Hence, researchers have considered solid-state joining methods [ 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 ,…”

Joining immiscible materials such as copper and stainless steel together is a significant concern due to distinct mechanical and metallurgical properties across the joint line, such as melting points, the coefficient of linear thermal expansion, and thermal conductivity. The joint properties of copper to stainless steel welds are in great demand for various mechanical components of the international thermonuclear experimental reactor, ultra-high vacuum system, plan wave linear-accelerator or linac structure, and heat exchanger. These dissimilar-metals joints offer excellent flexibility in design and production, leading to a robust structure for many cutting-edge applications. Hence, the present article reviews the copper to stainless steel joining mechanism under different solid-state processing conditions. The present understanding says that defect-free strong joints between the dissimilar metals are systematically possible. Apart from this understanding, the authors have identified and highlighted the gaps in the research exploration to date. Moreover, a sustainable methodology to achieve a desirable weld of copper to stainless steel depends on favorable processing conditions.

“…4b. According to Shanjeevi et al [31], the temperature rise in the weld interface during friction welding and the alloying elements at the weld interface may deteriorate the impact toughness of the welded joint. The faying surfaces of the materials to be joined by friction welding can show their effect on the performance of the welds manufactured [32].…”

Welding dissimilar metals by fusion welding process is a tough task, as both metals have different thermomechanical properties. In this study, experiments are carried out to join aluminium AA6063-T6 and steel AISI304L dissimilar alloys with different faying surface modifications through a continuous drive friction welding process (CDFW). This study aims to introduce the joining methods and evaluate the performance of their fabricated joints through microstructure and mechanical characterisations. Here, friction time (3, 5, and 7 s) is varied, whereas friction and upset pressures are kept constant. The faying surface-modified specimens are welded at constant chuck rotational speed 1300 rpm. The surface of the AISI304L specimen is buttered with pure aluminium and welded with an AA6063-T6 specimen. Similarly, the faying surface of the AISI304L specimen is tapered and welds with AA6063-T6 specimens having different modifications like a flat, tapered, and internal groove on their faying surfaces. Thus, different welding trials with different friction timings are conducted for each modification. The results of such joining methods like axial shortening, microstructures, EDS spectrums, tensile properties, impact strength, fractography, and Vickers microhardness are discussed and compared in this paper. The surface modifications with friction time improved the strength and 108.8 % joint efficiency.

“…In order to assess the influence of factors on the response, the means and Signal-to-Noise ratios (S/N) for each control factor can be calculated. The signals are indicators of the effect on average responses and the noises are measures of the influence on the deviations from the sensitiveness of the experiment output to the noise factors (Shanjeevi et al, 2017). The appropriate S/N ratio must be chosen using previous knowledge, expertise, and understanding of the process.…”

Friction welding (FW) is a solid state technique used mostly for joining similar or dissimilar materials owing to batch production with less time consumption. In friction welding, the joints are formed in the solid state by utilising the heat generated by friction. The objectives of this project is to obtain friction weld element of 17-4 PH Stainless steel alloy (Grade 630) and optimising the friction welding parameters in order to establish the weld strength and its quality. In this research work, the experiment is undergone to examine the tensile strength of friction welding 17-4 PH Stainless steel alloy. The experiment is conducted by varying the input parameters like rotational speed, friction and forging force, friction and forging time using Taguchi's L9 orthogonal array. For each experiment tensile strength was examined and the optimum welding condition for maximising tensile strength was determined.
