Metal joining is an integral part of the manufacturing process, where components of similar
material or two different materials are assembled in a complex system. Welding techniques …

Refill friction stir spot welding (RFSSW) is a solid-state spot joining method that has attracted
more and more attention from academia and industry at present. RFSSW has been …

0 mm thick 2219-O (upper plate) and 8.0 mm thick 2219-C10S (lower plate) were
successfully fabricated using refill friction stir spot welding (RFSSW), and the microstructure …

A novel refill friction stir spot welding (RFSSW) technique employing large-sized tools is
proposed. The microstructure and mechanical properties of joints produced with a large …

Defect-free joints were produced in 2.0 mm thick 7075-T6 Al alloy by refill friction stir spot
welding using a modified tool. Weld performance was evaluated in terms of microstructure …

Abstract The dissimilar Modified Friction Stir Clinching (MFSC) process between AA6061-T6
and AA5754-O aluminum alloy sheets was examined. The effect of shoulder feature …

Refill friction stir spot welding, also known as friction spot welding (FSpW), is a solid-state
welding process suitable for spot joining of lightweight materials. Through the efforts of …

The present work investigates the effect of rotational speed on joint quality during Friction
Stir Spot Welding (FSSW) using a consumable pin, where a consumable pin is used with a …

The mechanical properties and failure process of 2 mm-thick 5052 Al and 6 mm-thick 2A12
Al fabricated by refill friction stir spot-welding were investigated. The hooks were bent …

Structural damage and fatigue life of engineering materials are controlled by inherent
defects and the nature, level, and location of applied external loads. This paper studies the …
