The effect of the microstructure heterogeneity on the tensile plastic deformation characteristic of friction-stir-welded (FSW) dual-phase (DP) steel was investigated for the potential applications on the lightweight design of vehicles. Friction-stir-welded specimens with a butt joint configuration were prepared, and quasi-static tensile tests were conducted, to evaluate the tensile properties o...

In the present study, lap joints of dissimilar 5052 aluminum alloy and pure copper were fabricated by friction stir spot welding process. The work was aimed to find simultaneous effect parameters such as tool rotary speed (1000, 1500, 2000 rpm) dwell time (5, 10, 15 s) on shear force (LSF), hardness, microstructure evolution. Also, statistical models quality characteristics developed understand...

The reliable production of high-quality lithium-ion battery components still poses a challenge, which must be met to cope with their rising demand. One key step in the sequence is process cell-internal contacting, during electrode carrier foils anode and cathode are joined arrester. This usually done ultrasonic or laser beam welding. Both joining processes, however, show limitations concerning ...

Friction stir spot welding of dissimilar aluminum and copper sheets was investigated in details using Taguchi approach this study. Analysis variance conducted to identify the effective parameters their contributions on mechanical performance. The findings revealed that outputs followed normal distribution. results indicated rotational speed with contribution 87.7% most parameter maximum tensile...

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 comb...
