Abstract

Proses pengelasan SAW menggunakan fluks yang berbentuk seperti pasir yang berfungsi melindungi logam pengisi yang mencair saat proses pengelasan agar tidak terjadinya kontaminasi dengan udara luar sehingga didapatkan hasil pengelasan yang cukup baik. Sedangkan elektroda SMAW (Shielded Metal Arc Welding) diselaputi atau dilindungi oleh fluks dengan proses pengerjaan secara manual. Penelitian ini bertujuan untuk menganalisa perbandingan hasil pengelasan dengan menggunakan metode standar WPS PS-03 (Original) dan WPS PS-03R (Repair), dengan menggunakan pengujian impact untuk mengetahui ketangguhan pada spesimen S355G7+M. Pengujian ini bertujuan untuk mengetahui ketangguhan impact pada bagian hasil pengelasan pada WPS PS-03 (Original) dan WPS PS-03R (Repair). Spesimen WPS PS-03R memiliki nilai lebih besar di bandingkan dengan spesimen WPS PS-03. Apabila nilai kekuatan spesimen semakin besar, maka semakin kuat dan tangguh pula pada spesimen tersebut. Temperatur pada spesimen sangat berpengaruh terhadap keuletan atau kegetasan suatu logam. Semakin tinggi temperaturnya maka semakin ulet logam tersebut begitupun sebaliknya.

Abstract

This study investigates the effectiveness of Magnetic Particle Inspection (MPI) in optimizing welding preparation for the back gouging of boom structures in hydraulic mining shovels. The primary objective is to evaluate MPI's efficiency in detecting surface and near-surface defects during the pre-welding stage, thereby improving the overall welding quality of boom structures, which play a critical role in supporting heavy loads. MPI is utilized as an initial inspection method prior to Ultrasonic Testing (UT), enabling early detection of potential defects and reducing the likelihood of failures during subsequent UT evaluations. The study reveals the presence of linear and rounded discontinuities that may compromise weld integrity. By applying MPI early in the process, the need for rework during UT is minimized, resulting in cost and time savings. Furthermore, the findings of this study contribute to supporting two key organizational initiatives—People, Quality, Velocity, Cost (PQVC) and Built-in Quality (BIQ)—which aim to enhance both the efficiency and reliability of the welding process.
