Auto repair sheet metal work refers to the work of repairing a damaged part without replacing any of them. Repair technicians are required to have a high level of skill and to be able to work flexibly. If the work of experts can be quantified and visualized, it may be possible to transfer the skills to non-experts in a shorter time. Thus, in this study, technicians repaired a dent made on the press line of a passenger car fender using a hammer and dolly. The purpose of the research is to analyze the working time and working process during the repair. The sheet metal repairs were classified into five steps: “Hammering” (H), “Adjustment and position check of the dolly” (D), “Check by hand” (CH), “Check by eye” (CE), and “Other” (O). It was found that experts tend to spend longer than non-experts on step D.
