STRUCTURAL INTEGRITY
In the structural integrity Lab, we characterize the mechanical behavior of a wide variety of materials, steels, castings Aluminum Alloys, Copper, titanium etc, as well as their welded joints.

We have a metallographic laboratory equipped with the latest systems of optical and electronic microscopy, in the we perform macrographic and micrographic tests to determine the macro and microstructure of the samples under test and in this way, assess the fitness of the material.

One of our differential values is the ability to perform all preliminary operations, machining and preparation of tested specimens, in our facilities without the need for outsourcing, maintaining at all times the traceability of samples tested. We can also guarantee at all times the confidentiality of the work since none of the phases of the test are outsourced.

  • Traction tests.
  • High and low temperature tensile tests.
  • High temperature corrosion tests.
  • Shock bending tests (Charpy).

EQUIPMENT:
  • Universal mechanical testing machines with capacities between 600 kN and 100 N.
  • Contact and Video Extensometry.
  • Charpy pendulums adapted to European and American standards (UNE-EN-ISO 148-1, ASTM E 23).
  • Impact machine 1600 J capacity.
  • Metallographic laboratory equipped with:
    • Precision cutters.
    • Automatic polishers.
    • Stuffers.
    • Optical microscopes.
