Unsuitable working positions, as they cause disorders in the muscle skeletal system, also lead to a decrease in productivity. Therefore, the primary goal of the ergonomic discipline is to improve the working conditions, improve the quality of work and life of the workplace, and improve the efficiency. For the purpose of preventing disorders of the muscle skeletal system, ergonomic risk assessment methods are applied in the workplace and the workload is reduced by the arrangements made. In this study, the methods REBA, OWAS, OCRA, QEC and ManTRA, selected according to frequently repeated static and dynamic positions and upper end positions, were applied in a workshop of furniture manufacturing, and the risk assessment of pneumatic welding and pneumatic welding work that could pose a risk from an ergonomic point of view was made. The results of the assessments have found that the most suitable ergonomic risk assessment method for cases where the upper body areas such as hands, arms, rear and shoulder are used intensely in pneumatic climbing and pneumatic climbing work is the OCRA method. The OCRA method, by dividing a circle time into stations, ensures that each technical movement is included in the individual analysis and a detailed assessment is made.
