| Summary: | Welding is a crucial process in the repair and installation of pipes in a Steam Power Plant (PLTU). However, manual pipe welding takes a long time, increasing the risk of errors and operator physical fatigue. To address this issue, the Auto Rotated Welding (ARW) system was developed, an automated welding system that is more efficient and accurate. ARW can enhance efficiency and productivity in PLTUs while improving worker safety.
This research aims to design and implement the ARW system with an application for pipe welding with two-axis motion. The mechanical design involves welding machine components, electrical panels, pipe spindles, and a two-axis welding system with servo and inverter control. The system features a manual mode for pipe diameter adjustment and an automatic mode for autonomous welding based on input pipe length and rotation speed through the HMI. The welding time estimation feature of the system helps improve the efficiency and accuracy of pipe welding and optimizes operator work schedules.
Test results show that the optimal pipe translation speed to achieve the desired welding width, which is approximately 11-12.5 mm/s has been achieved. The ARW machine can produce welding with an error tolerance of around 2 mm from the desired dimensions. Furthermore, welding efficiency using the ARW machine is higher compared to manual welding by humans, achieving an efficiency improvement of 157-314%.
Although the ARW machine demonstrates excellence in precision and welding efficiency, human intervention is still required to achieve more uniform results and meet desired thickness. The use of the ARW machine offers a promising alternative to enhance the quality and consistency of pipe welding results.
