Evaluation of pore sizes in welded joints made in various constructional materials on the basis of penetrant testing by colour method

[摘要] It has been compared the dimensions of indications obtained in colour liquid-penetrant inspection. The indications arose from simulated pores drilled in test elements. The series of penetrant tests included different structural materials. On the basis of test results it has been ascertained the possibility of evaluation of the pores depth as well as it has been determined recommended development times for different constructional materials
