Evaluasi Proses Pengelasan dan Pengujian Ketahanan Korosi pada Konstruksi Kapal

Abstract

This research focuses on the analysis of welding techniques and their impact on the corrosion resistance of ship hull plates. The study was conducted using Almarine Steel plates with thicknesses ranging from 100 to 150 mm. Welding was performed using the Gas Metal Arc Welding (GMAW) method, and corrosion testing was carried out by submerging specimens in seawater for 10 days. The results show that, although slight weight loss occurred, the corrosion rate remained within acceptable limits for marine constructions. The impact of welding temperature and porosity on corrosion rate acceleration is discussed. The findings highlight the importance of controlling welding conditions to enhance the longevity of ship structures exposed to harsh marine environments.
