Welding systems in technological processes are being changed by the emergence of modern information technologies such as the Internet and things, big data, artificial intelligence, cloud computing and smart manufacturing systems are developing widely. Intelligent welding systems using these technologies are attracting attention from the academic and industrial communities. Intelligent welding is the use of computers to imitate, augment and/or replace human operators sensing, learning, decision making, monitoring and control, etc. This is achieved by combining the advantages of human and physical systems into intelligent cyber systems.
