Influenced by the high solubility of hydrogen in aluminum alloys and the formation of low-melting-point eutectics during the deposition process of Al-Zn-Mg-Cu alloys, porosities and cracks are likely to occur in the deposited parts, which directly and severely reduces mechanical properties. The characteristics and advantages of wire arc-directed energy deposition, as well as the process characteristics under different heat sources, were summarized and analyzed in this work.

The cutting-edge methods that have been adopted by researchers in recent years to reduce and suppress metallurgical defects were also introduced. In terms of suppressing pores, plastic deformation methods represented by interlayer rolling and the application of external fields can be used to reduce the density of hydrogen pores. Moreover, the crack susceptibility of Al-Zn-Mg-Cu alloys can also be reduced by means such as adding other elements to generate nano-phase particles.

Despite these advantages, traditional manufacturing methods often struggle to achieve precise fabrication control and optimize material properties, creating a critical gap in the effective production of these composites. In contrast, laser-assisted manufacturing (LAM) presents a promising alternative, leveraging the unique capabilities of laser energy for accurate material processing. This review systematically examines recent advancements in LAM techniques for carbon fiber-reinforced thermoset composites, addressing the underlying principles, diverse processes, and applications within the automotive and aerospace industries. Specifically, it explores the intricate mechanisms by which laser processing enhances the precision and quality of composite fabrication, including the effects of laser parameters on material properties and their implications for end-use performance. The novelty of this study lies in synthesizing existing knowledge while highlighting significant research gaps in the current literature, such as the limited investigation of laser-material interactions specific to thermoset composites and the need for standardized testing methodologies. Furthermore, this review identifies opportunities for interdisciplinary research, combining insights from materials science, mechanical engineering, and manufacturing technology to develop innovative solutions that maximize the potential of laser-assisted manufacturing. By elucidating the physical behavior of thermoset composites and evaluating the effectiveness of laser processing, this study not only contributes to a deeper understanding of this rapidly evolving field but also serves as a roadmap for future research directions.

The results show that both the plume area and the total intensity of the SMI signal are positively correlated with the weld penetration depth, and the frequency-domain features of the plume signal have a higher correlation than the time-domain features. Compared with the peak frequency, the centroid frequency of plume signal has higher sensitivity and adaptability to working conditions when reflecting the changes in the penetration depth.

However, piercing CFRP with a rivet leg causes significant damage, thereby reducing joint performance. To address this issue, this study proposes a novel process called flat electromagnetic self-pierce riveting with no concave die (FE-SPR) to join 2.0-mm-thick CFRP and 5052 aluminum alloy sheets. This method is an improvement based on traditional semi-hollow rivets to enhance structural strength and reduce CFRP damage. A comparative analysis of cross-sectional quality, quasi-static mechanical properties, forming mechanisms, and failure behavior were conducted between joints fabricated with traditional semi-hollow rivet (T-rivet) and novel semi-solid rivet (N-rivet). The results showed that the N-rivet joint, unlike the T-rive joint, exhibited upsetting deformation of the rivet shank and secondary expansion of the rivet leg. These features help suppress CFRP damage and increase undercuts. The average area of CFRP damage for T-rivet joint was 33.99 mm², 135.1 % higher than the N-rivet with 5°. The peak load and energy absorption of the N-rivet with 5° were 4154 N and 11.81 J, 18.3 % and 13.5 % higher than T-rivet joints, respectively. All joints exhibited one failure mode, characterized by rivet pull-out from the aluminum plate while maintaining adhesion to the CFRP plate.

This study aims at controlling stress and deformation of as-built thin walls by applying a double electrode arc-DED technique with lower heat input. By introducing an additional branch electrode to divert some current from the main wire, the heat input to deposited layers is reduced. Double electrode arc-DED has the potential to achieve higher deposition rates and lower heat input to deposited layers without compromising the forming quality. The novelty is that how the branch current affects the temperature, RS, and deformation of walls in double electrode arc-DED is revealed by using finite element simulation. A composite heat source model is developed to characterize the thermal effect of the double electrode arc. Experimental tests check the finite element model's effectiveness. The simulation results are in good agreement with the experimental results. Compared to conventional gas metal arc-DED, the high-temperature zone on as-built layers shrinks, and the melt pool's peak temperature and length decrease in double electrode arc-DED. As the branch current increase from 0 to 105 A, the maximum longitudinal RS on as-built layers decreases from 292 to 265 MPa, and the maximum deformation on the substrate reduces by 1.5 mm, indicating that introducing a branch arc can effectively reduce the heat input, RS, and deformation in arc-DED.
