Quality control

Among other areas, our company specialises in up-to-date methods of metal working. The experience we gain from co-operation with domestic and international enterprises is focused on the precision and machine-building industry. Therefore, it is a must for us to make accurate control measurements that help to determine if our products are of high quality. Our measuring office uses state-of-the-art, precise measuring machines and instruments and the personnel has suitable qualifications and certificates of competence. From the beginnings of our company we have been guided by the principle of client partnership focused on meeting customer requirements and expectations in every aspect.

SERVICES

  • Three-dimensional geometrical measurements made by means of the WENZEL coordinate measuring machine and portable measuring arm type FARO (measurements of shape deviations, position, distance, diameter, roundness, parallelism, squareness, concentricity, angle etc.);
  • Two-dimensional measurements made by means of high-accuracy measuring column (height meter) type TESA – the device that measures in one or two axes; we use it to measure length, height, depth, steps and spacings on geometrical elements with flat/parallel and cylindrical round surfaces and diameters of holes and shafts;
  • Use of FARO laser scanner for creating a body model of physically existing product or structure (used for designing) and comparing the real product against design model;
  • Non-destructive testing of welded joints in steel structures and sheets:
    • Visual tests (VT) carried out according to the PN-EN 970 standard; quality levels as per the PN-EN ISO 5817 standard;
    • Ultrasonic tests (UT) for welded joint and sheets with a minimum thickness of 6 mm, carried out by means of the KRAUTKRAMER flaw detector – detecting of internal flaws with the size above 0.01 mm, including surface and subsurface flaws (cracks, delaminations, material discontinuities etc.); the instrument is also able to measure thickness, first of all for structures strongly exposed to corrosion, where conventional method measurements are not possible (pipelines, tanks, silos etc.); examinations are carried out in compliance with the PN-EN 1712 and PN-EN10160 standards; quality levels as per the PN-EN ISO 5817 standard.
