Macroscopic examination

The macro-graphic examination is performed on joints made by full or partial penetration weld, as well as corner joint, butt-joints and T-joints; macro-graphic examinations are performed on multiple types of junctions, with common or special geometry (eg. tube-sheet).
This test allows to detect any possible defects in the weld's cross section and to assess them according to European and International standards.
The latest generation digital camera employed can take high resolution photographs of the examined section and, by connecting it to the computer system, it can record and provide a file that is then reproduced in print on test certificates.

Microscopic examination

Micro-graphics examinations on metallic materials are a type of characterization of the materials performed with a microscopic examination which reproduces the structure of metals to identify the different inter-metallic phases, their shape and distribution and to detect the size of the grain.
