This research aims to determine the quality of 3F blunt connection (T-Joint) and 2G shielded metal arc welding (butt joint) of the welding products of the regional selection contestants of ASEAN Skill Contest-Vocational High School (ASC-VHS) in Yogyakarta province. This study was implemented using a discrete approach. The data in this research were collected using a check list for the quality assessment of welding engineering students through a visual inspection and measuring tool for welding gauge. This research was conducted in the fabrication workshop, Department of Mechanical Engineering, Faculty of Engineering, Yogyakarta State University. The population of this study was all contestants of the 2019 ASEAN Skill Contest (ASC) regional selection in welding in the Yogyakarta Special Region. The results of this research show that the quality of the student competencies is still below The Welding Institute (TWI) standard. The aspect that becomes the weakness of contestants in the implementation of the ASC-VHS regional selection for welding includes a lack of understanding and knowledge in determining the welding requirements especially in identifying the welding code, selecting the current Welding, recognizing the type of metal material, recognizing the type of shielded metal arc welding electrodes, and knowing the function of occupational safety and health. Also, welding defects were found in the welding products.
