Summary: The alloy aluminum of the 5000 series has high strength due to solid solution strengthening of Mg, but the strength is reduced when welding due to the selective evaporation of Mg. Laser-arc hybrid welding maintains the strength by supplementing the missing Mg element from the filler wire, resulting in a tensile strength greater than 85% of the parent metal.

Summary: To achieve stable arc length and droplet transfer, understanding the power-arc model and the relationship between various parameters in pulsed gas metal arc welding (P-GMAW) process is crucial. In this study, a linear model of the GMAW process was analyzed with reasonable assumptions, and a mathematical power-arc model of P-GMAW was established through experimental statistical methods using a commercial welding power supply. The mathematical model was then combined with an adaptive arc length control strategy in the P-GMAW process of Al-Mg alloy, using a self-developed welding power supply. Experimental results showed that the arc length remained uniform and achieved the desired droplet transfer mode without spatters and cracks, indicating the feasibility of the adaptive arc length control strategy in Al-Mg alloy welding.

Summary: TIG arc additive manufacturing experiments were conducted using TiB2 nanoparticle-reinforced 7075 aluminum alloy welding wire. The microstructure and mechanical properties at different locations on the welded plate were analyzed. The top location had a fine dendritic microstructure induced by solidification, while the middle location had equiaxed grains. The bottom location had larger grain size and homogeneous distribution of secondary-phase particles at the grain boundary or inner grains. The mechanical properties were the best at the top location, with decreased tensile properties and micro-hardness from the middle to the bottom location. The combination of fracture elongation and maximum tensile strength for the 7075 aluminum alloy welding wire was determined to be 361.8 MPa, higher than samples processed by general arc additive manufacturing.

Summary: In this study, different current modes were used to butt-weld 1460 Al-Li alloy plates. The effects of these current modes on the weld microstructure and mechanical properties were compared. The results showed that modulating pulsed current can refine the grains in the weld zone and fusion zone, and significantly increase the quantity and width of a fine strip-like equiaxed grain zone. Both P-VPTIG and DP-VPTIG processes effectively enhanced the strength and elongation of the joints.

Summary: This study compares the mechanical properties of aluminum alloy joints prepared by conventional friction stir welding (FSW) and tungsten inert gas (TIG) arc assisted FSW. The results show that TIG arc assistance significantly improves the tensile strength and elongation of the joints. The improvement can be attributed to the elimination of defects, reduction of onion rings area, and formation of a higher density of hardening precipitates.

Summary: The study found that proper gas pressure in the micro drainage cover can improve the welding process and formation of underwater welds during local dry underwater MIG welding experiments, while excessive gas pressure can lead to worse welding results. High-speed photography of arc combustion and metal transfer under different gas pressure revealed that the most ideal conditions were both 0.2 MPa of the shielding gas pressure and drainage gas pressure at a water depth of 20 cm.

Summary: Metal-thermoplastic hybrid structures have shown effectiveness in achieving lightweight design in aircraft components. However, the differences in physical and chemical properties between metal and thermoplastic pose challenges in fabricating high-reliability hybrid structures. A study discovers that covalent bonding at metal/thermoplastic interfaces plays a crucial role in the interfacial reliability of these structures. By grafting carboxyl functional group on polyetheretherketone (PEEK), the density and strength of interfacial covalency is increased, leading to the fabrication of high-reliability hybrid structures between PEEK and A6061-T6 aluminum alloy.

Summary: This study presents a bottom-up strategy of introducing heteroatoms into CFRTP/metal interfaces to reconstruct the interfacial chemical structures and manufacture high-reliability hybrid structures. By introducing oxygen and hydrogen heteroatoms through simple and green plasma polymerization, the joint strength of CFRTP/6061 hybrid structures is strengthened from 8.82 to 23.97 MPa. This heteroatom introduction strategy provides fresh insights into interfacial design concepts and has important implications for the future application of high-reliability CFRTP/metal hybrid structures.

Summary: In recent years, 3-D reconstruction has been widely used in various fields, including robot pose estimation, mine exploration, and building of digital twins. While visual-based reconstruction methods have good real-time performance and high frequency, they are slightly inadequate in scenes that require high accuracy with no obvious demand for update frequency. To address this issue, a new visual-based pose estimation and 3-D reconstruction method based on image feature extraction and point cloud recognition was proposed in this research, which improves the accuracy of visual-based pose estimation methods. The method was tested in different scenarios and showed significant improvement in reconstruction accuracy while maintaining low-latency performance.
