Abstract: The frame of the computer aided technology system of covered electrodes quality control has been designed.With VB, the functional transplant of Word, embedding MATLAB to calculate, and statistics and diagraph of EXCEL, exploitation of the system database on SQL Sever 6.5 has been accomplished and through technical realization system visits to database.With all these techniques, certain function, such as electrodes properties predicted based on artificial neutral network, raw material recording, quality and consumer management and craftwork consultation have been well tested by the system.The sy stem function is formidable, and the interface is friendly, and it may be used as a powerful tool E4303 electrode design and the technical management.
