Macroexamination is used to get a low magnification picture of the sample
With macroexamination it is possible to examine the sample for uneven structure and measure e.g. wall thicknesses of tube walls and weld geometry.
Macroexaminations are most often needed in weld quality assurance.
- Weld cross-sections in qualification, production and performance tests
In addition to weld examinations, typical examinations are:
- Material orientation examinations
- Tube and profile wall thickness measurements
- Fracture surface examinations in failure analyses
