In order to detect welding defects and incompatibilities in the macro or microstructure of welded joints, macroscopic and microscopic examinations are performed.
The tests are made on appropriately prepared specimens (grinded, polished, etched) on the cross section of the weld. Precise geometrical measurements of the welded joint cross section are essential for the proper quality assessment of the joint. Hence, such measurements are performed with the aid of stereoscopic microscope allowing the measurements by means of specially designed software. The quality assessment of welds in micro and macrostructure is performed by the experienced and qualified personnel of Destructive Testing Laboratory.
Metallographic test is performed in compliance with:
- PN-EN ISO 17639
- our own test procedure
