Abstract: In order to actively respond to the company and national policies, improve the construction of digitalization and informatization, and in view of the pain points, expectations and special requirements in the construction process of welding and installation projects, welder personnel allocation management and welding process in the construction process of civil projects, major engineering projects and nuclear power engineering projects, it is proposed to implant and transform the traditional welding machine with the internet of things module,and use the advanced communication information technology and big data analysis technology in the internet of things to realize the configurable switching of welding power communication mode, welding man-hours, visual big data analysis of welding parameters such as welding current and welding voltage, and management and distribution of welding processes. In order to realize the integrated network management of man, machine, method and environment in the welding process, establish a database of man, machine, welding time, welding parameters and welding process, process and analyze the data, realize big data analysis and intelligent welding, and optimize the construction management to provide a foundation.
