Special Issue Information

Dear Colleagues,

This Special Issue aims to bring together recent scientific advancements and innovations in the field of Friction Stir Welding (FSW) and Friction Stir Additive Manufacturing (FSAM) and related technologies. The focus will be on experimental and simulation investigations, and high-quality contributions that demonstrate significant advancements in FSW and FSAM variants and applications will be considered for publication in this issue. Crystals is one of the most prominent journals related to high-tech industries. In this regard, FSW and FSAM are two significant processes in advanced welding and advanced manufacturing processes, which are widely employed in high-tech industries. FSW and FSAM are widely used for joining different materials, such as aluminium, magnesium, titanium alloys, mild steel, stainless steel, etc.

Topics of interest include, but are not limited to, the following:

  • Variants of FSW and FSAM, such as Friction Stir Spot Welding (FSSW) and refill FSSW.
  • Computational modelling and simulations.
  • Microstructure and mechanical properties characterization.
  • Quality inspection methods.
  • Equipment and tooling development.
  • Process monitoring, control, and automation.
  • Manufacturing applications.

We cordially invite you to contribute your articles if your work meets these requirements.

This research focuses on the computational modelling and comparative analysis of friction stir welding (FSW) and stationary shoulder friction stir welding (SSFSW) applied to AA6061-T6 aluminium alloy. SSFSW, an FSW variant, employs a stationary shoulder and a rotating pin. This study introduces a numerical model for both processes, using the innovative Smoothed Particle Hydrodynamics (SPH) technique to capture their distinct thermo-mechanical characteristics. The aim is to unravel its mechanics and multi-physics in SSFSW and compare it with conventional FSW. The temperatures predicted by the model exhibited a close agreement between the advancing side (AS) and retreating side (RS). Plastic strain patterns show that regular FSW is different from SSFSW. In SSFSW, the strain is less, and the plastic area is comparatively slightly narrower. The distinct “ironing effect” resulting from the stationary shoulder in SSFSW reduces the heat-affected zone (HAZ). Yet, it maintains efficient plasticisation and material flow within the pin-affected zone (PAZ). This research emphasises the significant impact of temperature, strain, material flow, and thermo-mechanical characteristics on the quality of joints. Future suggestions include exploring process parameters more broadly, examining dissimilar welding techniques and hybrid approaches, and comprehensively investigating the diverse effects of SSFSW under various configurations and joint angles.
