Summary
The subject is focused on diagnostic and casting quality control. Students are acquainted with casting defects classification according to Czech and international standards. The attention is devoted to causes of casting defect formation and prevention of its formation. Basic methods of quality control and testing methods of casting properties are also presented here.
