  • destructive tests including: tensile, bending, breaking tests on materials and welded joints; hardness measurement, metallographic examination, impact strength;
  • eligibility of welding technology according to PN EN ISO 15614 (including WPQR);
  • possibility of technical supervision over non-destructive testing that is conducted by our clients (3rd degree certificates);
  • technical supervision over offshore-type constructions;
