Mechanical-Metallographic Laboratory

E-mail Print PDF

Laboratory has personnel potential and suitable equipment for mechanical and metallographic testing of welded joints and base materials.

Mechanical testing:

  • tensile
  • bend
  • hardness
  • cupping

Metallographic testing: macroscopic, microscopic

Mechanical-Metallographic Laboratory  is accredited for following tests (Certificate preview – here):
