        abstract = {Welding of circular components requires uniform and controlled rotation to achieve consistent bead formation, proper heat distribution, and reliable joint strength. Manual rotation often results in irregular motion, operator fatigue, and variations in weld quality. To overcome these issues, this work presents the design and experimental evaluation of an electric rotating disc system developed for circular welding applications.
The proposed system integrates a 12V, 5A, 25 RPM DC geared motor, a chain–sprocket reduction drive, and a PWM-based speed controller to deliver smooth, low-speed rotation with adjustable RPM. A 12V, 15A SMPS is used to ensure stable power delivery to the motor and control unit. The mechanical design includes a mild steel rotating disc and a rigid frame to support varying workpiece sizes and welding loads.
Experimental testing shows that the system achieves high torque at low rotational speeds, enabling steady and uniform movement of circular components during welding. Speed variations were evaluated and correlated with welding time, demonstrating the machine’s ability to maintain smooth rotation under different conditions.
The developed mechanism offers a compact, reliable, and cost-effective solution that improves weld accuracy, reduces human dependency, and enhances overall productivity in industrial and workshop environments},
