Since about 10 years, Usinor has been extensively developing and implementing automatic surface inspection systems (designated as ASIS). Research work enhanced by industrial developments in partnership with Matra, has produced systems capable of detecting and classifying defects according to the expectations of the users. The data obtained are transformed by a computer-aided post-treatment into automatic grading of coil quality and into guidelines to the operator for the evaluation of its compliance with specifications.
