Welcome to Scotia Non-Destructive Testing
Liquid penetrant testing is a method that is used to reveal surface breaking discontinuity by bleed out of a coloured or fluorescent dye from the discontinuity.
The technique is based on the ability of a liquid to be drawn into a "clean" surface breaking discontinuity by capillary action. After a period of time called the "dwell," excess surface penetrant is removed and a developer applied. This acts as a blotter. It draws the penetrant from the flaw to reveal its presence. Colour (contrast) penetrants require good white light while fluorescent penetrants need to be used in darkened conditions with an ultraviolet "black light".
This method of Non Destructive Testing (NDT) is widely used throughout both the Aerospace and General engineering industries.
Liquid Penetrant Testing Course (PT)
The training program covers 50% theory and 50% practical application, allowing time to obtain good foundation in the method of NDT by practicing a large variety of inspection techniques under the supervision of our qualified instructors.
