AUTOMATED OPTOELECTRONIC SYSTEM OF DETECTING WELD JOINTS AND DEFECTS ON THE MOVING METAL STRIP DURING CONTINUOUS COLD-ROLLING
The paper describes construction and principle of operation of an optoelectronic system of detecting weld joints and defects on the moving metal strip during continuous cold-rolling. To increase the reliability of detecting, the system uses stroboscope effect synchronized with the rolling speed. System characteristics in relation to rolling parameters are determined.
