Design of welding armrest based on ergonomics analysis: Case study at educational institution In Johor Bahru, Malaysia

© 2006-2018 Asian Research Publishing Network (ARPN). Nowadays, many high technology machines, mechanical devices, and modern mechanical processes exist to create better products and to produce them instantly. The welding process is one of the mechanical processes to produce a product, and it requires the welder to stay in a static posture for long period of time. Due to this problem, the process is seen to be unsafe and unhealthy to the welder. This study focuses on students who perform welding activities in the welding workshop of an educational institution in Johor Bahru, Malaysia. The aims of this study were to propose a design to improve the welding process and reduce the ergonomics problem. The study used Rapid Upper Limb Assessment (RULA) analysis to analyze the posture of students during the welding process. The RULA analysis and proposed design were performed using CATIA V5R19 software. The results show that the proposed design gave better results which reduced the RULA score from 6 to 2 while the color turned from orange to green (acceptable position).
