“…For that reason, the high absorption laser light, such as diode laser, can be used to initiate the laser welding process for aluminium. A higher absorption means less reflection and the energy from the laser source can be used more efficiently to melt the metal [80].…”

Aluminium castings have been widely used in many industries, including automotive, aerospace, telecommunication, construction, consumer products, etc., due to their lightweight, good electric and thermal conductivity, and electromagnetic interference/radio frequency interference (EMI/RFI) shielding properties. The main applications of aluminium castings are in automotive industry. For lighweighting purposes, more and more aluminium castings are used in the automotive vehicle structures to reduce weight, improve fuel efficiency, and reduce greenhouse gas emissions. However, due to the features of cast aluminium, such as porosity, poor surface quality, a tendency toward hot cracking, and low ductility, joining these materials is problematic. In this paper, the joining technologies for aluminium castings and the related issues, mainly cracking and porosity, are reviewed. The current state-of-the-art of joining technologies is summarized, and areas for future research are recommended.

Reducing weight and improving energy efficiency are key design goals in the automotive industryIn order to reduce the weight of the car body, engineers often use plastics in the parts of the car that require less strength. However, due to the difference in material properties, when using plastics to connect steel frames, there are disadvantages such as small interface area, large number of interfaces, and poor reliability of plastics, which may have a great impact on the safety of the car. Therefore, these plastic parts Joinery to the steel frame of the car needs careful consideration. Various methods, such as welding, bolt and nut connection, riveting, and crimping, were considered to connect plastic and metal in automobiles. This article first introduces the specific implementation of the joinery method between plastic and metal, and investigates their process difficulty, interface strength, vibration resistance and the least negligible cost. Discusses where these processes are suitable for use in the car, where they are currently used, and explores potential future developments.

“…66 The laser welding applications include aircraft engine and transmission parts, alternators, fuel injection devices, biomedical devices, and microelectronic components. 67–71 Meanwhile, laser transmission welding (LTW) is a proven technology that can join plastic to plastic and has numerous advantages over adhesive joining and mechanical joining. In the LTW, the laser beam transfers through the component top layer to the component bottom layer.…”

In the twenty-first century, the application of carbon fiber reinforced polymer (CFRP) materials in the vehicle industry are growing rapidly due to lightweight, high specific strength, and elasticity. In the automobile and aerospace industries, CFRP needs to be joined with metals to build complete structures. The demand for hybrid structures has prompted research into the combination of CFRP and metals in manufacturing. Aluminium and CFRP structures combine the mechanical properties of aluminium with the superior physical and chemical properties of CFRP. However, joining dissimilar materials is often challenging to achieve. Various joining technologies are developed to produce hybrid joints of CFRP, and aluminium alloys include conventional adhesives, mechanical and thermal joining technologies. In this review article, an extensive review was carried out on the thermal joining technologies include laser welding, friction-based welding technologies, ultrasonic welding, and induction welding processes. The article primarily focused on the current knowledge and process development of these technologies in fabricating dissimilar aluminium and CFRP structures. Besides, according to Industry 4.0 requirements, additive manufacturing-based techniques to fabricate hybrid structures are presented. Finally, this article also addressed the various improvements for the future development of these joining technologies. Ultrasonic welding yields the maximum shear strength among the various hybrid joining technologies due to lower heat input. On the other hand, laser welding produces higher heat input, which deteriorates the mechanical performance of the hybrid joints. Surface pretreatments on material surfaces prior to joining showed a significant effect on joint shear strength. Surface modification using anodizing is considered an optimal method to improve wettability, increasing mechanical interlocking phenomena.
