Abstract
Bisclad 600 merupakan jenis material yang terdiri dari material utama (baja karbon rendah) dan material pelapis(cast iron) disatukan dengan proses cladding. Material ini memiliki kekuatan yang tinggi dan ketahanan abrasi yang baik sehingga dapat diaplikasikan pada casing Rotary Feeder. Penelitian ini bertujuan untuk menganalisa pengaruh arus dan jenis elektroda las yang divariasikan terhadap struktur mikro, kekerasan, dan hasil las Bisclad 600. Pengujian yang dilakukan meliputi uji penetrant, uji kekerasan, uji makro, dan uji metalografi. Pengelasan dilakukan menggunakan variasi arus 80A, 90A, 100A, 110A dengan jenis elektroda ENi-CI, ENi-Fe-CI, dan 308L. Hasil sambungan yang memadai dan nilai kekerasan weld metal yang tertinggi sebesar 307HV pada arus 100A dengan jenis elektroda CIN-2. Berdasarkan hasil pengujian didapatkan pada weld metal, semakin besar arus maka menghasilkan struktur mikro yang halus.

Bisclad 600 is a type of material consisting of the main material (low carbon steel) and coating material (cast iron) is joined with cladding process. This material has high strength and good abrasion resistance so it can be applied to Rotary Feeder casing. This study aims to analyze the influence of current and type of welding electrodes are varied on the microstructure, hardness, and welding results Bisclad 600. The tests include penetrant test, hardness test, macro test, and metallographic test. The welding is carried out using variations of currents 80A, 90A, 100A, 110A with ENI-CI, ENi-Fe-CI, and 308L electrodes. The result of good joinning and the highest hardness of weld metal is 307HV at 100A current with CIN-2 electrode type. Based on metallographic observation, finer microstructure was obtained with the increase of welding current.
