PT penetration method

Capillary method is very widely used surface method; it is intended for the inspection of defects related to surface of the material or component. Its advantage is the fact that it can be used on magnetic, non-magnetic, metallic and non-metallic materials. With this method it is possible to visualise surface defects such as cracks, holes, non-adhesion of compositions etc. The high quality performance of this inspection is connected with several requirements on ambient temperature and quality of the tested surface.


Basic types of capillary method:
