Special Issue Information

Dear Colleagues,

Since the invention of friction stir welding (FSW) in 1991, this technique has demonstrated significant advantages in joining low melting point materials and has fostered innovations across multiple industries, such as aerospace, automotive, shipbuilding, and railways. Building on the principles of FSW, several innovative manufacturing technologies have emerged, including friction stir processing, friction stir fabrication, and the recently developed solid-state additive manufacturing technique, additive friction stir deposition. These friction stir-related manufacturing technologies have shown considerable scientific use and hold vast application potential.

This Special Issue aims to capture the latest trends and developments in these friction stir-related manufacturing technologies. We invite researchers worldwide to submit original research papers, review articles, and short communications that explore the latest advancements in friction stir manufacturing technologies. We are particularly interested in papers that provide new insights, innovative approaches, and substantial advancements in the application of these techniques.

Potential topics include, but are not limited to, the following:

  • Developments in tool design in friction stir related manufacturing processes
  • Innovations in microstructural modifications through friction stir processing
  • Applications of additive friction stir deposition in complex part fabrication
  • Comparative studies of friction stir manufacturing technologies and conventional manufacturing processes
  • Theoretical modeling and simulation of friction stir manufacturing processes
  • Case studies demonstrating industrial applications and efficiencies gained through these technologies

We look forward to your innovative contributions to this dynamic field.

Hook defects are common in FSW butt–lap joints, resulting in a significant safety hazard for the parts that suffer cyclic load. In this study, a numerical simulation based on the Euler–Lagrange coupling method was conducted to investigate the formation process of hook defect during FSW of AA6005-T6 aluminum alloy. The simulation results were validated with experimental data, showing good agreement. The formation of the hook defect is caused by the threads on the probe promoting material flow in the thickness direction. In order to further study the effect of probe morphology on hook defects, three kinds of probe models with different morphology were established and numerically simulated by the CEL method. The simulation results show that all three kinds of probes can reduce the size of the hook. The welds obtained using the left–left probe (LLP) and the three-plane probe (TPP) both exhibit void defects, while the welds obtained by a right–left probe (RLP) have no internal void defects. The experimental results show the same characteristics as the simulation results, and the size of the hook defect is reduced to 58 μm. Full article
