Abstract: A set of intelligent control system for TIG/MIG welding process was designed by using the cloud platform technology of Internet of Things. The main technological parameters and processes in the welding process were controlled by the intelligent control system. The intelligent control system mainly includes production management PC, cloud servers, data monitoring system, 4G intelligent control module, master-slave station, servo motor system and the welding process control system. The application of this intelligent control system can solve the the previous discrete, difficult to obtain field equipment data and can monitor and process data remotely in real time. After field application, the intelligent control system has good stability, high reliability, accurate and real-time remote monitoring of TIG/MIG welding process and control of welding parameters. It meets the requirements of welding production environment, and lays the foundation for future intelligent welding workshop.
