Penelitian ini mengkaji pengaruh variasi frekuensi getaran meja getar terhadap sifat mekanik hasil
pengelasan TIG pada material aluminium paduan 6061. Pengelasan dilakukan dengan menerapkan
frekuensi getaran sebesar 30 Hz, 40 Hz, dan 50 Hz selama proses berlangsung. Evaluasi sifat
mekanik dilakukan melalui uji kekerasan Vickers dan pengujian kekuatan tarik. Hasil penelitian
menunjukkan bahwa variasi frekuensi getaran berpengaruh signifikan terhadap peningkatan
kekerasan, ke homogenitas struktur mikro. Frekuensi tertentu menghasilkan struktur butir yang lebih
halus, yang berdampak pada peningkatan sifat mekanik sambungan las. Secara keseluruhan,
penerapan meja getar selama pengelasan TIG dapat meningkatkan kualitas hasil las aluminium
6061.

This study examines the effect of vibration frequency variations of the vibrating table on the
mechanical properties of TIG welding results in aluminum alloy 6061 materials. Welding is carried
out by applying vibration frequencies of 30 Hz, 40 Hz, and 50 Hz during the process. Evaluation of
mechanical properties is carried out through Vickers hardness tests and tensile strength tests. The
results showed that the variation in vibration frequency had a significant effect on the increase in
hardness, to the homogeneity of the microstructure. Certain frequencies result in a finer grain
structure, which has an impact on improving the mechanical properties of the weld joint. Overall,
the application of vibrating table during TIG welding can improve the quality of 6061 aluminum
weld results.
