Abstract

Bengkel Truk Desa Balongbendo, Sidoarjo, tengah menghadapi beberapa kasus terkait proses pengelasan lantai bak truk yang terbuat dari pelat bordess setebal 3,2 mm. Permasalahan tersebut timbul karena pemilihan arus pengelasan yang tidak tepat untuk ketebalan pelat intan sehingga menghasilkan hasil pengelasan yang kurang optimal. Ketebalan pelat bordess yaitu 3,2 mm, mempersulit proses pengelasan karena memerlukan penyesuaian arus dan pola pengelasan yang tepat untuk memastikan pengelasan yang tepat dan sambungan yang kuat. Pemilihan arus pengelasan yang tidak tepat dapat menimbulkan berbagai masalah. Pertama, jika arus pengelasan terlalu rendah maka sambungan las akan lemah dan rawan retak atau putus saat digunakan. Kedua, jika arus pengelasan terlalu tinggi, pelat bordess dapat berubah bentuk atau meleleh secara berlebihan sehingga menyebabkan kerusakan pada pengelasan. Untuk mengatasi masalah ini, diusulkan strategi penelitian yang melibatkan variasi arus pengelasan dalam tiga Arus : 115 Ampere, 130 Ampere, 145 Ampere dan 160 Ampere dan menambah pola dalam pengelasan yakni pola vertical dan zigzag. Selanjutnya akan dilakukan uji tarik dan struktur mikro terhadap pelat intan setebal 3,2 mm. Penelitian ini bertujuan untuk mengetahui pengaruh arus pengelasan dan pola pengelasan terhadap kekuatan tarik dan struktur mikro dengan menggunakan metode pengelasan SMAW dengan elektroda E7018. Penelitian ini menggunakan bahan plat bordes dengan ketebalan 3,2 mm, dimana bahan diberi perlakuan pengelasan dengan variasi arus 115 Ampere, 130 Ampere, 145 Ampere dan 160 Ampere dengan menggunakan teknik las SMAW dengan elektroda E7018 dengan diameter 3,2 mm. Spesimen dilakukan dengan pengujian tarik dan struktur mikro
