The proliferation of the industry 4.0 promotes the development of manufacturing technologies. In this context, advanced information technologies have paved ways for increasing the intelligence and networking capabilities of current industrial systems. Thus, there is a trend to focus on the research of intelligent manufacturing technologies, in which intelligent welding technologies is an important aspect. This paper explains several crucial concepts related to the industry 4.0 including the cyber-physical systems（CPSs） and the production chain in industry. Conceptual fundamentals of the industry 4.0 are further illustrated. After reviewing the role of welding technologies in each industrial revolution, we propose the core of intelligent welding technologies based on a 5C architecture of CPSs. The research directions and challenges of intelligent welding technologies in the context of the industry 4.0 in the future are pointed out as well. This paper summarizes the characteristics of the industry 4.0 and the key technologies of intelligent welding, which provides guidance for further research in this domain.
