IIS Group boasts a longstanding experience in metallographic investigations. The Italian Institute of Welding Group's laboratory is equipped with up to date facilities for preparation, observation, recording of metallographic samples.

Preparation, polishing, etching, resin incorporation and observation at optical or scanning electron microscope is our common procedure for metallographic investigations.

The critical interpretation of results permits to add value to metallographic testing. The expertise we have gained over decades of services supplied to the Industry, has made available at our Group the knowledge of original material properties, fabrication processes, damage mechanisms occurring during the operational life of components. All this enables us to establish fundamental links  between the metallographic structures that we observe and  the quality of the fabrication  process and/or degradation/damage phenomena active during service
