Magnetic testing

Magnetic testing is a fairly simple non-destructive testing method. The basic principle is to magnetize the object by applying the magnetic particles which then show the problematic area by accumulation of magnetic particles on parts where the magnetic field is „leaking“.

With the use of magnetic flux it is possible to find flaws on the surface of the object as well as directly below the surface. Materials that can be tested must have magnetic properties (ferromagnetic materials).

This method is used for:

  • testing welding joints for surface cracks
  • testing rotor bodies in steam turbines and generators for surface cracks
  • testing steam turbines casted housings for cracks
  • testing rotor blades on steam turbines for cracks
  • testing tube plates in steam boliers for cracks

Other methods

Radiographic testing

Radiography is a process of recording inner and outer defects in three-dimensional objects on a two-dimensional film plane.

Ultrasonic testing

Ultrasonic testing is based on the fact that solid materials are good at carrying sound waves.

PAUT- Phased array ultrasonic testing

An advanced method of ultrasonic testing that has applications in industrial nondestructive testing.

Magnetic testing

With the use of magnetic flux it is possible to find flaws on the surface of the object as well as directly below the surface.

Penetrant testing

Penetrant testing is one of the first widely accepted non-destructive testing method.

Visual inspection

Visual inspection is the oldest and the most common non-destructive testing method.
