The inspection is carried out using optical tools, such as magnifying glasses or borescopes, and allows the detection of surface defects such as cracks, porosity, lack of fusion, undercuts, or geometric irregularities. This method enables the assessment of the welds&#8217; compliance with project specifications and current regulations.

The principle is based on detecting surface and subsurface discontinuities by using ferromagnetic particles applied to an induced magnetic field. Discontinuities interfere with the magnetic flux and cause visible accumulations of particles. This method is particularly useful for detecting cracks, inclusions, and welding defects that are at or near the surface.

The method is based on the propagation of ultrasonic waves within the material, which are reflected at the discontinuities. The analysis of the reflected signal allows for locating and assessing the size and nature of the defect. This examination is performed with a special probe and portable equipment.
