The capabilities of industrial processes have witnessed exponential growth, evolving from the development of steam engines in the 1st generation to the integration of the Internet of Things (IoT) and cyber-physical systems (CPS) during the 4th Industrial Revolution. Among the rapid innovations in diverse industrial areas, one trending research field is the welding process, which has significantly transitioned from the forging method used during ancient civilizations to the utilization of gas welding with advanced robotic machinery in the contemporary world. However, current industrial operations still rely on conventional approaches to refilling gas tanks for industrial operations. This project aims to address this gap by proposing an Industrial Internet of Things (IIoT)-based system to monitor the percentage of liquefied gas in a welding tank through edge and cloud, emphasizing the seamless integration of the existing industrial environment. The first section of this paper thoroughly reviews the related work and industrial solutions before presenting the proposed system architecture. Then, we discuss each component in the project's architectural layers and present the implementation results, including an intuitive user interface and an alarm feature based on threshold via email service for a non-interruptive welding process. Finally, we present the conclusions, including the limitations and possible future work.
