It is used when it is necessary to identify various surface defects. Capillary methods are used to control objects of any size and shape, made of ferrous and non-ferrous metals and alloys, glass, ceramics, plastics and other non-ferromagnetic materials. With the help of capillary (color) flaw detection it is possible to control objects made of ferromagnetic materials.
The advantages of capillary method of control:
- allows to carry out accurate localization of small defects and characterize them with great accuracy;
- allows you to extend the scope of other visual methods of quality control of welding joints;
- increases the field of view for surface defects;
- it is not an expensive method.
