In order to meet the needs of the study of composite arc images and multi-channel electrical signals in the welding process, a synchronous acquisition and analysis system of arc images and welding electrical signals was developed based on computer technology and Lab VIEW development environment. System hardware includes high-speed camera, synchronous controller, electrical signal acquisition circuit, laser backlight, motion control platform, industrial computer, etc. The system software includes synchronous acquisition module, playback module and data analysis module. The experimental results show that the system can realize the statistics and analysis of the synchronous acquisition and playback of arc images and multi-channel electrical signals and the characteristic parameters of welding, which can be used as an effective test platform for further research on composite welding and various arc welding.
