“…The current welding technologies based on friction generally utilize the friction between the workpieces (such as rotary friction welding, and linear friction welding) [1] or between workpiece and tool (such as friction stir welding) [2][3][4][5] to generate heat to soften the material and form plastic material flow. In this way, the original interface between the workpieces is broken to form an effective joint.…”

Friction stir welding is a promising solid-state welding technique. However, the issue of tool wear and break restricts its wider industrial application. To avoid the tool wear and break occurring in conventional friction stir welding (FSW), a new modification of the FSW process using a tool made by the identical material as the workpiece has been developed and conducted on pure aluminum. We named this process as Vortex-FSW (VFSW) because it depends on a vortex material flow to realize the welding and joining. The weld macro- and micro-structures are like that in conventional FSW. However, the tool exit-hole in conventional FSW is replaced by a lug boss. The mechanical properties are also equivalent to that in conventional FSW. The principle of this new process is introduced in this paper.

“…Compared with other joining techniques such as RSW, friction stir spot welding (FSSW) and its variant "linear" friction stir welding (FSW) [10], clinching and adhesive bonding, SPR has proven to be an effective process to join dissimilar materials, from aluminium with composite [11] to aluminium with advanced high strength steel [12]. RSW, on the other hand, is typically used in welding steels than welding other light alloys [13][14][15].…”

Self-piercing riveting (SPR) is a cold forming technique used to fasten together two or more sheets of materials with a rivet without the need to predrill a hole. The application of SPR in the automotive sector has become increasingly popular mainly due to the growing use of lightweight materials in transportation applications. However, SPR joining of these advanced light materials remains a challenge as these materials often lack a good combination of high strength and ductility to resist the large plastic deformation induced by the SPR process. In this paper, SPR joints of advanced materials and their corresponding failure mechanisms are discussed, aiming to provide the foundation for future improvement of SPR joint quality. This paper is divided into three major sections: 1) joint failures focusing on joint defects originated from the SPR process and joint failure modes under different mechanical loading conditions, 2) joint corrosion issues, and 3) joint optimisation via process parameters and advanced techniques.

This study presents an investigation of the plunge stage in joining AZ31B magnesium alloy with friction stir welding using two different 3D finite element models based on Arbitrary Lagrangian–Eulerian formulation and Coupled Eulerian–Lagrangian formulation. The investigations are made with the ABAQUS program. Johnson–Cook plastic material law and Coulomb friction law are used in both models. Models are compared in terms of temperature, strain distribution, and processing time. In both models, very similar temperature and strain distributions are obtained in the weld zone and the models are validated by experimental results. In addition, with the increase in the rotational speed of the tool, temperature and strain in the welding zone increase similarly in both models. In the model using the Arbitrary Lagrangian–Eulerian formulation, mesh distortions occur when high mesh density is not created in the plunge zone. No problems related to mesh distortion are encountered in the model using Coupled Eulerian–Lagrangian formulation. Moreover, it is found that the model using the Coupled Eulerian–Lagrangian formulation has a lower processing time and this processing time is not affected by the rotational speed of the tool.
