This study aims to: (1) uncover the learning model applied in 3G SMAW welder competence formation in SMK YP Gajah Mada Palembang and (2) determine the effectiveness of the applied learning model. This research is a descriptive study with interviews and documentation of data collection techniques. The results of the study are: (1) The learning model used to form 3G position welder competencies in students is a project-based learning model, (2) The learning model in SMK YP Gajah Mada Palembang has been effectively applied viewed from the percentage of pass students in competency test of expertise. In reverse, welding activities had not been effective to form 3G Position SMAW welding skills. The main instrument in welding practices is welding machine, meanwhile, SMK YP Gajah Mada Palembang only operates 4 welding machines that can be used with a ratio of 1 machine for 8 people. Consumables for 32 students per semester in welding practices are iron plate ± 100-150 kg, grinding blade 7-8 pieces/semester, electrodes ± 11-12 boxes/semester and time consumed for welding practices for entire 1 semester 17 times meetings with a total time of 98 hours or 4,410 minutes.
