The objective of this course is to give a foundation in the history of Liquid Penetrant testing, steps for performing liquid penetrant. To give a understanding of the characteristics of penetrants, emulsifiers, and their developers. To be able demonstrate penetrant testing methods and techniques. Finally, the nature of defects and inspection of welded joints will be learned and demonstrated.
• To become familiar with Penetrant testing materials and their properties.
• To analyze and understand specific gravity and viscosity.
• To understand technique selection and penetrant removal.
• To learn the difference in penetrants, emulsifiers, and developers and their uses.
• To become familiar with different Liquid Penetrant testing practices.
• To determine visible and fluorescent indications.
This course is designed to provide a hybrid experience, including classroom and hands-on training. This class will be divided in the following way:
80% Classroom Training
