“…Laser welding brazing (LWB) techniques offered additional advantages such as increased flexibility and adoptability when welding dissimilar metals [28,91,92,112,113]. To this end, LWB technique is suitable for joining dissimilar materials having large differences in melting points such as Mg/Ti [18,[114][115][116], Al/Ti [117], and Al/steel [118,119]. In particular, welding of magnesium alloys to steel by LWB process was achieved with addition of third material or mutual diffusion of alloying elements.…”

Hybrid structures built using Mg/steel are expected to have an increasing impact on the future developments of the manufacturing sector, especially where lightweight structures are required in order to reduce fuel consumption, greenhouse gases and improve efficiency of energy-converting systems. To this end, there is a pressing need for a joining technology to produce effective and low-cost dissimilar Mg/steel joints. Joining of these materials has always been a challenging task for researchers, due to the wide discrepancies in physical properties and lack of metallurgical compatibilities that make the welding process difficult. Based on the existing literature, a successful joint between magnesium alloys and steel can be achieved by inserting an interlayer at the interface or mutual diffusion of alloying elements from the base metal (BM). Thus, intermetallic phases (IMCs) or solid solutions between Mg and the interlayer and also the interlayer and Fe formed at the interface. However, the interfacial bonding achieved and the joints performance depend significantly on the intermediate phase. This paper reviewed the research and progress in the area of joining of Mg alloys to various grades of steel by variety of welding processes, with focus on the techniques used to control the morphology and existence state of intermediate phase and improving the mechanical properties.

As lightweight automotive structures improve fuel efficiency and reduce carbon dioxide emission, they have garnered extensive attention. Vehicle mass reduction, which is a key problem for next generation eco-friendly vehicles, can significantly increase mileage. Hence, industries have committed to replace conventional materials with lightweight materials, such as advanced high strength steel. Additionally, automotive industries are hindered by challenges in the field of joining technology. A novel welding technology called resistance element welding (REW), which is an appropriate thermal-based joining method, was developed recently for joining hybrid materials with other structural steel grades. In this study, the state of the art joining and the process characteristics for dissimilar metal joints have been presented because related studies show limited investigation in this area. Following by the state of them, the principal and welding quality of REW, experimentally and numerically, are reported to give comprehensive information on the current practices and research interest related to technologies. Finally, extensive work was concentrated on portional joining optimization techniques to improve different materials.

“…In this study, laser welding/brazing (LWB) was used to produce Al/Cu joints. Researchers often offset the laser beam to control the melted amount of the base metals [31][32][33], and the formation of the IMCs could be inhibited. In this research, copper has a high melting point and low light absorption.…”

The influence of tin foil and Ni coatings on microstructures, mechanical properties, and the interfacial reaction mechanism was investigated during laser welding/brazing of Al/Cu lap joints. In the presence of a Zn-based filler, tin foil as well as Ni coating strengthened the Al/Cu joints. The tin foil only slightly influenced the joint strength. It considerably improved the spreading/wetting ability of the weld filler; however, it weakened the bonding between the seam and the Al base metal. The Ni coating considerably strengthened the Al/Cu lap joints; the highest tensile strength was 171 MPa, which was higher by 15.5% than that of a joint without any interlayer. Microstructure analysis revealed that composite layers of Ni3Zn14–(τ2 Zn–Ni–Al ternary phase)–(α-Zn solid solution)–Al3Ni formed at the fusion zone (FZ)/Cu interface. Based on the inferences about the microstructures at the interfaces, thermodynamic results were calculated to analyze the interfacial reaction mechanism. The diffusion of Cu was limited by the Ni coating and the mutual attraction between the Al and Ni atoms. The microstructure comprised Zn, Ni, and Al, and they replaced the brittle Cu–Zn intermetallic compounds, successfully strengthening the bonding of the FZ/Cu interface.
