Ergonomic Design of Arc Welding Workstation Using Younger Age Group Operators
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
Industrial jobs involving arm posture have a strong association with musculoskeletal disorders and injuries. It also affects the performance and effort (i.e. effort in holding, lifting, and lowering, etc.) of the worker. The current study is an attempt in that direction. This study involves the ergonomic design of arc welding workstations. Here work height, working distance and angle of work have been considered as anthropometric factors. Twenty-seven right-handed males of age group (18 to 30 years) university students and employees participated in the experimental investigations. Grip force and welding time for a pre-assigned task were recorded as measures of subject performance. The collected experimental data were analysed through MANOVA using Minitab statistical software. Results indicated that the work height, distance of worker, and angle of work have a significant effect on operator's performance in the arc welding environment for younger age group subjects. It is further explored that interaction of work table height and workers distance has a significant effect on the performance of worker for these subjects. Further analysis according to the mean value comparison method revealed that 80 cm work height, 65 cm operator working distances and zero degree work angle resulted in optimum grip force, and 80 cm work height, 65 cm operator working distances and 40-degree work angle resulted in optimum welding time in case of 18-30 year age group workers.
