The laboratory carries out metallurgical testing in order to:

• detect superficial or internal discontinuities.
• ascertain the microstructure and the grain size of the parent and weld material.
• determine coating thickness via optical microscopy.
• assess the thermal treatment they have been subjected.
• determine eventually their compliance with the standards.

Methods used are: stereoscopy, optical microscopy (x1000) and electron microscopy (x150000), combined with hardness and chemical analysis.
