Bogie frame is an important part of high-speed train.The welding quality of bogie frame is the key factor to determine the quality of bogie.It is urgent to strengthen the control of welding production process through information system.The intelligent welding group control system

a platform for bogie frame welding process management and control

is established based on the Internet of things

big data and cloud computing technology.The system is applied to monitor the status of welding machine in real time

realize online control of welding process parameters

digital management of welding process and statistical analysis of data

have improved the ability of welding production management

and provided important data support for managers to optimize the production process

allocate resources and assess welders.
