This study aimed to determine students' ability to practice carbon steel welding. Students' ability in welding is an essential factor in obtaining good welding results and as a provision in obtaining certification. This study uses a quantitative descriptive approach. The subjects in this study consisted of 40 students from the mechanical engineering education study program at the Faculty of Engineering, Yogyakarta State University. The research instrument uses a Likert scale with four alternative answers. Data acquisition was analyzed using the quantitative description. The results showed that: (1) the preparation of seam welding by most of the students was still in the good category, (2) the seam welding process by most of the students was still low; and (3) the welding results of most of the students are still sufficient. Students' ability in welding practice must be improved through preparation, and good processes, so that they will produce welds that are by standards. [ABSTRACT FROM AUTHOR]

This research is an advanced study on testing welding results with visual test methods. This study aims to determine the level of independence of student welding results and the cause of the emergence of these indications. This study uses quantitative descriptive research, where the data that appears is then described according to existing facts and then presented using numbers and statistical analysis. The research was implemented at the Department of Mechanical Engineering Education, Yogyakarta State University, with 25 students of the Department of Mechanical Engineering Education. The research object is a workpiece resulting from 3G position welding conducted by 25 students. The data collected is interpreted using standard procedures from AWS and ASME. The results showed 3G welding of students who passed the Liquid Penetrant Test based on AWS as many as five students, while based on ASME as four students. The indications that most appear in the specimens studied are rounded. Manifestations of welding defects occur because students pay less attention to welding procedures, unstable welding arc positions, and incorrect selection of welding parameters. [ABSTRACT FROM AUTHOR]
