“…Once the first phase of control is satisfied, and it is confirmed that a certain percentage of penetration has been achieved, controlled weld joint proceeds to further control procedures to check appearance of weld, strength and at last corrosion resistance as final advantage of joined materials. Over the last decades, there have been improvement in joining materials technology and anticorrosion behaviour [4][5][6][7].…”

Quality control of welded joint is an indispensable part of the welding production process. As part of spot resistance welding group, cross-wire welding process showed great application for welding of products for everyday usage. The non-contact quality control checking is fit for purpose due to specific characteristics of welded products that consist of two cross welded wires or a combination of wires and strips. This work proposes a new method for detecting and measuring of required dimensional parameters, but also founds its applicability for other products if required. A crucial parameter of this research is the height of welded joint, which is necessary for calculating the penetration of the wire into the wire. The proposed measuring method with a reconfigurable measuring system is explained in this paper. The main component of this system is using a machine vision system, which has become an indispensable part of industrial metrology and is considered one of the industry 4.0 concepts. The calibration process for such systems could be very complicated. This work shows an elaborated calibration procedure for this kind of measuring system with referenced standards made for this purpose. Measurement results are compared with ones obtained by conventional method. The focus of vision system is a substantial part as it dictates the quality of the system. This research is done within the project in collaboration with the industrial sector and all samples are from real processes. The results of measured penetration on one product group are showing the applicability of a reconfigurable measuring system in the welding sector, and demonstrate that measurement of welding penetration based on machine vision is feasible and can ensure accuracy.

“…More specifically, adhesive joints present a more uniform stress distribution, help to avoid possible corrosion issues, and promote weight saving in comparison to mechanical joints [ 2 , 3 ]. In fact, recent studies have dealt with the development of novel joining techniques, such as electromagnetic-driven, self-piecing riveting for joints with dissimilar materials and with Al/steel substrates, examining their mechanical performance and corrosion properties [ 4 ], as well the joining quality [ 5 ] in comparison to adhesive and hybrid joints.…”

Fe3O4-Nanoparticle-Doped Epoxy Resin as a Detachable Adhesive by Electromagnetic Heating for GFRP Single-Lap Joints

et al. 2022

An adhesive based on a Fe3O4-nanoparticle (MNP)-doped epoxy resin was proposed for the development of detachable adhesive joints with GFRP substrates. The analysis of cryofractures showed that the increasing MNP content promotes a higher presence of larger aggregates and a lower sedimentation of nanoparticles due to the higher viscosity of the mixture. In this regard, the inclusion of expandable microspheres (MS) induces a more uniform dispersion of MNPs, reducing their sedimentation. The capability of the proposed adhesives for electromagnetic (EM) heating was also evaluated, with increases in temperature of around 100 °C at 750 A, enough to reach the Tg of the polymer required to facilitate the adhesive detachment, which is around 80 °C. Finally, the lap shear strength (LSS) of 14 and 20 wt.% MNP samples was evaluated in a single-lap shear joint with simultaneous EM heating. The LSS values were reduced by 60–80% at 750 A, thus promoting successful adhesive joint detachment under EM heating.

“…Since fatigue cracks generally originate inside the brittle IMC layer, researchers have recommended limiting the thickness of the IMC layer to less than 10 µm to achieve mechanically sound joints [10][11][12]. In contrast, solid-state joining methods, such as explosion welding, friction welding, riveted-adhesive hybrid joining technique, and electrically assisted pressure joining, avoid melting of the alloys and thereby avert most solidification defects [13][14][15][16][17][18]. Nevertheless, due to the need for high pressure to induce large deformation of materials and also to comply with safety restrictions, explosion welding [17] and friction welding [15] are generally limited to welding components made of highly ductile materials with simple shapes.…”

“…Electrically assisted pressure joining produces joints by establishing diffusion bonding under the joining conditions of plastic deformation and elevated temperature, which is generally necessary to extend the longer diffusion time to enhance the bonding strength [16]. Riveted-adhesive hybrid joining technique includes two joining methods of adhesive and riveting to enhance the reliability of joint, but it undoubtedly increases the process and causes the rise of cost [18].…”

Friction stir spot welding (FSSW) of dissimilar S45C steel and 6061-T6 aluminum alloy in a butt configuration is experimentally investigated. Butt spot welding is performed using a convex scrolled shoulder tool at different tool rotational speeds. FSSW butt joints are successfully fabricated by offsetting the tool to the steel side. The microstructures of the joints fabricated at three different tool rotational speeds are characterized using scanning electron microscopy and energy dispersive spectrometry. Microstructural analysis shows the presence of intermetallic compounds (IMCs) along the steel/aluminum interface. The thickness of the IMC layer and the tensile strength of the joint increase with increasing the tool rotational speed. The results of tensile tests and microstructural analysis show that the joint performance is closely related to the IMCs at the joint interface.
