Laboratories
Chemical analyzes and mechanical
tests are performed only by qualified, specially trained experts. Qualified teams consist of quality inspectors and certified NDT (non-destructive testing) engineers.
COMES NDT laboratory is designed to perform checks and measurements using non-destructive procedures for various parts in the production flow.
The following types of controls are performed in the
NDT laboratory
Control with penetrant liquids
in order to determine the external defects of rolled, forged, cast or welded structures; the materials used when performing the examination comply with ASME, ASTM and ISO and are supplied only from licensed manufacturers.
The NDT control is carried out in accordance with internal standards, in accordance with the requirements by the beneficiary. Quality assessment norms are in accordance with ASME, EN ISO.
Magnetic particle control
in order to determine the external defects of rolled, forged, cast or welded structures; the materials used when performing the examination comply with ASME, ASTM and ISO and are supplied only from licensed manufacturers. The magnetic powders used are supplied by authorized manufacturers. Norms for quality assessment are in accordance with EN, ASME.
Ultrasonic Control
Ultrasonic defectoscopy is applied to ferrous materials, based on the reflected pulse control method, with a working frequency in the range from 2 to 5 MHz, for the following: rolled profiles and plates, forgings and castings, pipes, welds and corners, thickness measurement.
Testing procedure in the
Mechanical laboratory
Tensile Test
at ambient temperature and high temperatures up to 800°C
Impact Test
with a Charpy pendulum and using the cryogenic chamber, allowing the test temperature of -60 °C; tests are performed according to ASTM and ISO standards.
Testing procedure in the
Chemical laboratory
Macrostructure, microstructure, hardness (Rockwell, Brinell, Vickers)
test the chemical composition of metallic, ferrous and non-ferrous materials using an argon spark optical emission spectrometer.
Our activities in the field of destructive and non-destructive control services are carried out in our testing laboratories accredited by RENAR and authorized by CNCAN, ISCIR, with authorized inspectors by ISCIR, EN, ASME level 2.
