Penetrant Testing (PT)

Course Overview:

Penetrant Testing (PT), also known as Liquid Penetrant Inspection (LPI), is a vital method in Non-Destructive Testing (NDT) used to detect surface-breaking defects in non-porous materials. This course offers participants a comprehensive understanding of PT principles, equipment operation, inspection techniques, and interpretation of test results. Through a combination of theoretical instruction and hands-on practice, participants will develop the skills necessary to perform PT effectively in various industrial applications.

Course Objective

Understanding PT Principles: Gain a thorough understanding of the principles behind penetrant testing, including capillary action, penetration of defects, and contrast enhancement.
Equipment Operation and Setup: Learn to operate PT equipment proficiently, including cleaning materials, penetrant solutions, developers, and inspection booths.
Inspection Techniques: Acquire proficiency in conducting PT inspections using both visible and fluorescent penetrant methods, including application, dwell time, and removal of excess penetrant.
Interpretation of Test Results: Develop skills in interpreting PT indications, distinguishing between relevant defects and surface contaminants, and evaluating the significance of detected indications.
Safety and Quality Assurance: Understand safety precautions associated with PT, including handling of chemicals and adherence to quality assurance protocols for reliable inspection outcomes.

Who Should Attend?

This course is suitable for professionals and technicians involved in materials testing, quality control, and inspection across various industries, including:

NDT Engineers and Technicians
