Lembar PengesahanA pressure vessel can be defined as a container that experiences both external and internal pressure due to the weight of the fluid it contains. To withstand the external pressure exerted on the pressure vessel, a saddle pressure vessel is required as a support. The placement of the saddle pressure vessel plays a crucial role in reducing the external load or force caused by the weight of the fluid being held (Novian Rizky, Miftachul Munir, and Indrawan, 2023). Welding itself generates tensile forces due to softening during the welding process, resulting in displacement values (Nishimura, 2021). This study aims to determine the influence of welding on the displacement values to prevent the pressure vessel from receiving excessive loads using a Leica 16 total station. The method involves collecting measurement data using the total station, followed by calculations comparing the coordinates before and after the welding process to determine the significant level of displacement that occurs. Monitoring results indicate that the displacement values of the saddle pressure vessel are relatively small, with the displacement values on the X-axis = -0.0008, Y-axis = -0.0004, and Z-axis = -0.0007, indicating that there are no significant changes occurring in the saddle pressure vessel after welding, or it can be said that the saddle position tends to be stable.otherTECHNOLOGY::Civil engineering and architecture::Geoengineering and mining engineering::GeoengineeringTECHNOLOGY::Civil engineering and architecture::SurveyingTECHNOLOGY::Engineering mechanics::Construction engineeringArticleNIM3322111009NIM3322101037NIDN0018088807KODEPRODI29301#TEKNOLOGI GEOMATIKA
