Determination of the Depth of Closed Blind Cracks in Non-metal Check Samples and Test Panels for Penetrant Testing

Abstract

Abstract. Check samples and test panels are used to quality assessment and comparing sensitivity of sets of penetrant material. Authors made research in field of manufacturing non-metal test-objects with specified parameters, such as length a width. The paper considers a technique to determine the depth of blind closed cracks in check samples and non-metal test panels for penetrant inspection with a special tool to measure the depth of the undercut depth or a gauge indicator on the outboard support.

Comparison of the Quality of Flaw Detection Materials Using Samples Developed for Liquid Penetrant Testing

“…Test panels were used to perform penetrant testing with different penetrant materials, and the resulting traces were recorded [9][10][11].…”

Analysis of Quality of Welded Joints of Iron-Concrete Products

“…Defects of welding [8] and reasons of their emergence in welded joints are various and specific for each type of welding and material type [9][10][11].…”

“…Important stage of welding process is the quality control, both of finished products and parameters of process quality. Detection of discrepancy can be considered as the cause for improvement of process conditions or a system in general [8].…”
