Analysis of quality student practice results in shielded metal arc welding

Abstract

This study aims to describe and determine the breakdown level of the V Groove welding results of students in Shielded Metal Arc Welding practice in the 3G (Vertical Up) position based on the American Welding Society standards. This study uses a quantitative descriptive research approach to describe the quality of the welding results. The collecting data in this study uses a visual assessment checklist based on AWS standards. The research conduct in a fabrication workshop at, Department of Mechanical Engineering Education, Faculty of Engineering, Yogyakarta State University. The data analysis technique was done by visually assessing students’ welding results and averaging them then describing them. The number of samples from this study were all training participants totaling 18 students. The results of this study indicate that: overall, the pass rate of students in welding the V groove connection in the 3G position SMAW practice is still meager, from a total of 18 students, none of them passed. Most students did not pass welding in the irregular bead, free from arc stray and spatter, undercut material, weld profile, and crater cross-section. The cause of student failures is due to a lack of understanding of how to avoid welding defects.
