Refill friction stir spot welding of aerospace alloys in the presence of interfacial sealant
نویسندگان
چکیده
Refill friction stir spot welding (refill FSSW) is one of the most industrially promising variants. The absence an exit hole improves effectiveness surface treatments and minimizes damage by fouling. Aerospace aluminium alloys AA2024-T3 AA7075-T6 with a thickness 2 mm were used in this investigation. A range values for rotation speed plunge depth experimented to determine process parameter combination based on cross-sectional analysis lap shear strength. effect interfacial sealant weld properties was determined both using combination. Fatigue life fractography scanning electron microscopy performed specimens without sealant.

Simulation of Robotic Friction Stir Welding of Aerospace Components
Friction stir welding (FSW) is an emerging manufacturing technology for aerospace structures. It will see widespread use in the future as it offers ways of creating lighter structures at lower manufacturing cost than traditional methods (riveting, adhesive bonding). Since its invention in 1991, FSW has known fast improvements and many studies have demonstrated its capability for joining a wide ...
متن کاملStudy of Mechanical Properties Change During Friction Stir Spot Welding of Aluminium Alloys
The Friction Stir Welding process is now 20 years old and the interest in it and its potential continues to increase dramatically. FSW can be applied to a multitude of products with varying material types and thicknesses. However, a continuous weld is not always required to meet the product performance requirements. Thus, one can consider some form of intermittent weld, such as Friction Stir Sp...
متن کاملFriction stir welding of dissimilar alloys – a perspective
Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions. The purpose of this special issue of Science and Technology of Welding and Joining was to assess the status of friction stir welding...

A liquation cracking mechanism of dissimilar Al alloys during the friction stir welding (FSW) is suggested in this study. To identify the mechanism, the precipitates were analyzed and Al-Mg-Cu phase diagrams were calculated. Electron backscattering diffraction (EBSD) analysis and electron probe microanalysis (EPMA) were also conducted. In the same manner as constitutional liquation, at high hea...
متن کاملFriction Stir Welding of Aluminum Alloys: A Review
Friction stir welding is a solid state joining process. High strength aluminum alloys are widely used in aircraft and marine industries. Generally, the mechanical properties of fusion welded aluminum joints are poor. As friction stir welding occurs in solid state, no solidification structures are created thereby eliminating the brittle and eutectic phases common in fusion welding of high streng...
