Ultrasonic Flaw Detection for Quality Assessment of Explosively Clad Plates

[摘要] The aim of this work was to study more thoroughly all problems relating to the evaluation of material defects connected with plate quality before and after explosive cladding. During testing great attention was paid to material defects in plates, the reasons for their appearance and possibility of detecting them by means ofultrasonic technique. It was most important to find out which defects were especially dangerous. The results of ultrasonic testing that relate to the quality of initial steel platesare described. Modelled defects of various sizes are ultrasonically tested and analysed. The properties of explosive welded jointsand cases of cracks in clad plates are tested. All these data can be helpful in the context of working outcriteria relating to the selection of initial plates for cladding.
