Abstract:

For information isolated island and loose management caused by artificial control in the welding process in ship building and boilers production, a digital control system is designed for welding, including data acquisition, production management and quality evaluation. The system is controlled comprehensively in real-time via internet. The design covers production of the welding process and quantitative evaluation of welding quality. The results show that the digital controlled welding system can effectively reduced efficiency caused by manual control, improving welding quality.

Key words: information management, process control, quality assessment, welding machine
