The shipbuilding industry has applied automatic welding systems to increase productivity as well address the shortage of skilled welder. However, a manual labor is still required in process where cannot be applied. Since past decade, number welders been continuously decreasing. Accordingly, various education equipment and have developed for order efficiency reduction training time . when educat...
