A Study on the Measuring Method of Work Parameters to Evaluate the Skill of FCAW Welding Trainee

다국어 초록 (Multilingual Abstract)

On industrial sites, FCAW is mostly performed by welders. In general, welder functional level evaluation is performed based on the appearance and mechanical testing of beads after welding. However, the actual welding quality obtained in the field is determined by the fluctuating characteristics of the working variables, depending on the welder’s skill. Therefore, with trainees, a rating system is needed to evaluate proficiency by measuring work parameters. In this study, two welding cameras were used to measure the work parameters of a welder who performed FCAW semi-automatic welding using CO₂ gas. A method of grading the welder’s proficiency by analyzing the average and standard deviation of work parameters, taking into account the important factors that affect weld quality, is presented. For Trainee to develop a desire to grow on their own, a method of grading proficiency was proposed using the changing characteristics of the work variables rather than the welding results.
