Summary: The zero-gap laser lap welding of steel and aluminum filled with TiC particles of different sizes was studied in this research. The addition of 10 µm and 50 µm TiC particles reduced defects and refined grains, while also improving mechanical properties. The 50 µm TiC filled joint showed certain plasticity compared to mainly brittle fractures in other samples.

Summary: Laser welding offers many advantages in the manufacturing of EV battery packs, with the ability to optimize results and tensile strength by adjusting output ratios and other conditions. Increasing power may widen weld seams and form small pores, but penetration depth does not significantly change.

Summary: In this study, an aluminum alloy sheet was successfully welded to a nickel-plated iron sheet using a silicon-containing aluminum filler by gas tungsten arc welding. The joint strength of the aluminum/iron interface was improved by the simultaneous addition of silicon and nickel, which resulted in a reduction in the intermetallic compound layer thickness and the refinement of its grains. The addition of silicon alone reduced the thickness of the intermetallic compound layer, while the addition of nickel further refined its grains. The combination of silicon and nickel showed the most effective improvement in joint strength.

Summary: Using twin-wire CMT with Al-Si filler enables dissimilar joining of materials, showing typical characteristics of common steel/aluminum weld brazing joints. Intermetallic compounds (IMCs) were found next to the steel and aluminum, with a total thickness of 2-4 micrometers. Proper wire feeding rate and welding speed can enhance wetting characteristics, while excessive heat input can decrease mechanical properties.

Summary: In this research, Cu-base fillers with different V ratios were designed for the butt joining of explosion-welded titanium/steel bimetallic plate. It was found that the V content significantly influenced the formation of compounds at the weld interfaces, which in turn affected the mechanical properties of the weld metals. Strategies for improving the overall mechanical properties in the future were suggested.

Summary: The use of multi-material structures is an effective solution to reduce weight and emissions in the automotive industry. However, joining aluminum alloys to steels is challenging due to their mismatched properties. Laser-based processes have been explored to overcome this issue and this review examines the recent achievements and progress in this field, evaluating factors such as joining conditions, filler materials, microstructure, and mechanical properties.

Summary: The implementation of a stationary shoulder in dissimilar joints of Al-steel and Al-CFRP using friction stir assisted scribe technology (FaST) resulted in viable joint strength and improved surface roughness. Interruption lap shear tests and computational modeling showed that joint failure typically occurs in the aluminum sheet, with a similar fracture path observed in both Al-steel and Al-CFRP joints.

Summary: The study indicates that during linear friction welding, short-term friction in the interfacial reaction layer leads to the formation of metastable Al-Fe intermetallic compounds and Al-Mg-Cr compounds, while long-term friction results in the formation of a fragile boundary, suggesting differences in the formation process of the layer.

Summary: The joining of aluminum alloy and Ti-Ni-Hf shape memory dissimilar metals was achieved by cold metal transfer (CMT) welding-brazing with an Al-based filler. The relationship between heat input, microstructures, and joint strength was investigated. The joint consisted of three regions: the Al/SMA brazing interface, weld metal zone, and Al-weld metal zone. The interfacial intermetallic compound (IMC) with a strip or needle-like morphology was identified as TiAl3. The IMC exhibited an inhomogeneous morphology along the brazing interface. The Ti-Ni-Hf SMA adjacent to the interface retained reversible martensitic transformation and its phase transition temperature slightly increased with distance from the interface. Increasing heat input led to an increase in IMC thickness and a decrease in joint strength. The maximum tensile strength achieved was 122 MPa at a heat input of 553.6 J/mm. Fracture initiation occurred at the interface between the IMC and Ti-Ni-Hf and propagated along the interface.

Summary: Laser-arc hybrid direct lap welding is an effective method for achieving high-performance welding of magnesium alloys to steel. By controlling the offset of the laser heat source, the mechanical properties of the dissimilarly joined Mg and steel were optimized. The tensile strength of the direct lap welded joint without filler wire or any interlayers reached 295.7 N/mm under ideal processing conditions, which is approximately 80% of the Mg alloy's nominal strength - an improvement not previously reported in the literature. The laser enhanced the wettability of the joint, and the laser keyhole played a critical role in strengthening the joint performance by pinning the weld seam, increasing the interfacial reaction layer, and altering the location of the crack source.
