چکیده
Friction stir welding (FSW) adalah suatu teknologi pengelasan yang merupakan proses solid-state joining bisa digunakan untuk menyambungkan material aluminium dengan mampu las rendah. Proses FSW memanfaatkan putaran dari tool menggesek dua buah lempengan logam akan disambung. Aluminium 2024 T3 ketebalan 4 mm disambung menggunakan variasi feedrate 13 mm/menit, 15 dan 25 kecepatan spindle 910 rpm kedalaman pin 3 mm. Pengujian dilakukan pengujian tarik, kekerasan uji struktur mikro pada masing-masing pengelasan.Hasil penelitian menunjukkan bahwa kekuatan tarik regangan tertinggi terjadi mm/menit sebesar 221,51 MPa 3,60. Kemudian terendah 198,63 2,26. Nilai di area nugget zone dihasilkan yaitu 137 VHN nilai 105 VHN. Hasil foto TMAZ (Thermomecanically Affected Zone) mengalami perubahan seiring berubahnya feedrate.

Emission of nanoparticles during friction stir welding (FSW) of aluminium alloys.
Friction stir welding (FSW) is now well established as a welding process capable of joining some different types of metallic materials, as it was (1) found to be a reliable and economical way of producing high quality welds, and (2) considered a "clean" welding process that does not involve fusion of metal, as is the case with other traditional welding processes. The aim of this study was to de...

متن کاملFatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
