“…Pegas merupakan suatu alat yang terbuat dari baja yang memiliki sifat elastisitas tinggi dan berfungsi sebagai penerima beban dinamis (Brandão, 2023;Fitriyus, 2023;Prasanna, 2023;Ranjan, 2023;González-Fernández, 2019;). Penggunaan pegas banyak ditemui dalam bidang teknik umumnya pada kendaraan bermotor, hal ini dikarenakan pegas memiliki peranan penting untuk memberikan kenyamanan terhadap pengguna kendaraan bermotor (Cortes, 2023;Romero, 2023;Wibowo, 2023;Ambade, 2022;Hariprasath, 2022).…”

Pegas daun merupakan suatu alat yang terbuat dari baja yang memiliki sifat elastisitas tinggi dan berfungsi penerima beban dinamis. Pada kendaraan yang banyak menerima beban besar seperti truk, penggunaan pegas daun sangat cocok digunakan karena memiliki sifat elastisitas yang bagus dan di imbangi dengan ketangguhan yang tinggi untuk menerima beban yang besar. Masalah yang sering terjadi pegas daun mengalami patah, jalan yang rusak dan beban muatan yang melebihi kapasitas menjadi penyebab pegas daun mengalami patah. Untuk memanfaatkan pegas daun yang patah agar bisa dipergunakan lagi yaitu dengan menggunakan teknologi pengelasan. Metode yang dipakai pada pengelasan berupa kampuh V, dengan arus 100 ampere menggunakan elektroda LB 52 U, pendinginan setelah pengelasan menggunakan variabel air kelapa, air garam dan oli. Hasil uji kekerasan didapatkan pengujian menggunakan pendingin air kelapa memperoleh nilai tertinggi yaitu daerah welding metal 31 HRC, daerah HAZ 56.5 HRC dan base metal 38 HRC. Sedangkan untuk uji impact ketangguhan tertinggi diperoleh pengelaan dengan media pendingin air kelapa dengan nilai impact 0.853 J/mm2.

“…Therefore, for plates of different shapes and sizes with the different medium boundary, when they are subjected to ultrasonic vibration, their ultrasonic field distribution is different [22]. However, in current ultrasonic-vibrationassisted welding, scholars neglect the superposition and interference of the ultrasonic field distribution and directly fix the ultrasonic at a certain position or fix the distance between the ultrasonic horn and the welding torch as a fixed value (or the closest position to the welding torch) [23]. In addition, when ultrasonic vibration propagates in solid metal plates, it will experience varying degrees of attenuation due to the different composition of the alloy, and diffraction will occur due to the hard points (some second phase) in the plate.…”

The study focuses on investigating the relationship between the ultrasonic effect and microstructure of ultrasonic-assisted gas tungsten arc welding (UA-GTAW) Inconel690 alloy joints. The influence of ultrasonic vibrations on Inconel690 plates was examined, while also clarifying the distribution pattern of the ultrasonic effect across the plate. Furthermore, actual welding experiments were performed by varying the distance between the ultrasonic horn and the welding torch. The results revealed that there were changes in both grain growth direction within the weld zone and refinement effects achieved under different distances. The optimal refinement of primary and secondary dendrite arm spacing was observed at distances of 60 mm and 180 mm between the welding torch and ultrasonic horn. The hardness of weld zone reached 235HV1 when the distance between ultrasonic horn and welding torch is 180 mm.
