Pengaruh Model Speciment Uji Tarik Pada Pengelasan Besi Fc-30 Di Lihat Dari Kekuatan Tarik Pengelasan

Abstract

Untuk mengetahui sifat logam maupun non logam salah satu pengujian yang digunakan adalah uji tarik. Prinsip dari pengujian ini adalah dengan memberikan beban gaya yang berlawanan arah pada kedua ujung specimen bahan material yang diuji, sehingga kekuatan dari bahan yang diuji dapat diketahui. Speciment penelitian ini menggunakan dua macam speciment uji tarik yang sesuai dengan standar internasional yaitu ASTM E 8 dan ASTM E 8M ini sesuai dengan standar Amerika jika di Jepang menggunakan standar JIS 2241, dari pengujian model ini dapat diketahui modulus elastisitas, regangan, reduksi dan tegangan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh model penampang speciment kotak dan model penampang speciment bulat dengan luasan penampang yang sama dilihat dari kekuatan tarik masing-masing speciment. Metode penelitian yang digunakan adalah metode eksperimen perbandingan, yaitu suatu cara untuk membandingkan antara dua indikator speciment yang berbeda model penampang dengan luasan penampang yang sama, untuk mengetahui kekuatan tarik masing-masing speciment . Dari penelitian yang dilakukan menghasilkan kekuatan tarik pada material dasar tertinggi sebesar 781,004Mpa dengan speciment bentuk kotak. Kekuatan tarik paling tinggi terjadi pada pengelasan menggunakan elektroda las LB-52 yaitu sebesar 1.193,033 Mpa penampang speciment kotak dan elektroda las CIA yang memiliki kekuatan tarik yang hampir sama yaitu sebesar 1.134,002 Mpa penampang speciment kotak. Sedangkan yang paling rendah adalah pengelasan menggunakan elektroda LB-52 yang tanpa dicelup oli dimana hampir sama dengan material dasarnya yaitu sebesar 403,802 Mpa penampang speciment bulat.
