Liquid (Dye) Penetrant Testing Method level-I & II

Liquid (Dye) Penetrant Testing (PT) is a non-destructive testing method used to detect surface-breaking defects in non-porous materials such as metals, ceramics, and plastics. This Level I & II course provides a comprehensive understanding of the principles, techniques, equipment, and applications of penetrant testing. Participants learn how penetrant materials identify surface discontinuities through capillary action and how indications are developed and interpreted. The course covers surface preparation, cleaning, penetrant application, dwell time, excess penetrant removal, developer application, inspection, and post-cleaning. It introduces visible and fluorescent penetrant techniques and their practical applications. Participants gain knowledge of relevant NDT procedures, inspection conditions, safety requirements, and quality practices. The training also explains common surface defects such as cracks, laps, seams, and porosity. Level II topics include test evaluation, interpretation of indications, reporting, and selection of suitable testing techniques. Practical exercises help participants develop inspection skills and understand real-world testing challenges. The course is suitable for personnel involved in quality control, inspection, maintenance, fabrication, manufacturing, and NDT activities.
