Abstract:
Aim: Present study aimed at reducing the musculoskeletal disorders and injuries in arc welding environment. Poor arm posture during various industrial applications, mainly results musculoskeletal disorders and injuries. It also affects the performance and effort (holding, lifting, and lowering) of the worker. Current study involves the ergonomic design of arc welding workstations. Method: Here, arc welding work height, working distance and angle of work has been considered as operator performance-affecting anthropometric factors. Twenty-seven right-handed males of age group (35 to 55 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: The results of this study indicated that work height, distance of worker, and angle of work have a significant effect on operator's performance in the arc welding environment for higher age group welding operators. It is further explored that interaction of work height and workers’ distance has a significant effect on the performance of the subjects. Further analysis on the basis of the mean value comparison method revealed that 80 cm work height, 65 cm operator working distances and zero degree work angle resulted optimum grip force, and 80 cm work height, 65 cm operator working distances and 20 degree work angle resulted optimum welding time in case of 35 to 55 year age group workers
