Abstract
Proyek ini bertujuan untuk mengevaluasi kualitas hasil pengelasan pada Top Deck Support Frame menggunakan dua metode pengelasan berbeda, yaitu Flux Cored Arc Welding (FCAW) dan Gas Tungsten Arc Welding (GTAW), melalui serangkaian Non-Destructive Test (NDT). Pengujian dilakukan untuk mengidentifikasi potensi cacat internal dan eksternal yang mungkin muncul selama proses pengelasan, seperti porositas, undercut, dan incomplete fusion. Proses pengelasan ini diuji menggunakan metode Visual Test (VT), Magnetic Particle Test (MT), dan Ultrasonic Test (UT) untuk mendeteksi ketidaksempurnaan dalam struktur hasil las. Selain itu, faktor-faktor seperti distribusi panas, deformasi material, dan ketahanan sambungan juga dianalisis untuk memahami pengaruh parameter pengelasan terhadap kualitas sambungan. Hasil pengujian menunjukkan bahwa pemilihan metode pengelasan yang tepat serta pengaturan parameter yang optimal sangat berpengaruh dalam meminimalkan cacat las dan meningkatkan keandalan struktur. Studi ini memberikan kontribusi signifikan dalam meningkatkan prosedur pengelasan dan kontrol kualitas di PT. PAL Indonesia, khususnya pada proses manufaktur di sektor industri maritim. Rekomendasi perbaikan diberikan untuk mengoptimalkan penggunaan NDT pada inspeksi kualitas pengelasan di masa depan.

This project aims to evaluate the quality of welding results on the Top Deck Support Frame using two different welding methods, namely Flux Cored Arc Welding (FCAW) and Gas Tungsten Arc Welding (GTAW), through a series of Non-Destructive Tests (NDT). Testing is carried out to identify potential internal and external defects that may appear during the welding process, such as porosity, undercuts, and incomplete fusion. This welding process is tested using the Visual Test (VT), Magnetic Particle Test (MT), and Ultrasonic Test (UT) methods to detect imperfections in the welded structure. In addition, factors such as heat distribution, material deformation, and joint resistance are also analyzed to understand the effect of welding parameters on joint quality. The test results show that choosing the right welding method and optimal parameter settings have a significant effect on minimizing welding defects and increasing structural reliability. This study makes a significant contribution to improving welding procedures and quality control at PT. PAL Indonesia, especially in the manufacturing process in the maritime industry sector. Recommendations for improvement are provided to optimize the use of NDT in future welding quality inspections.
