The static tensile test is the basic and most frequently performed test of the strength of materials. The test consists in stretching a standardized specimen in opposite directions until it breaks. We define such properties as: percentage reduction of the…
The aim of a bend test is performed to determine the mechanical properties of the material or to check the susceptibility to plastic deformation under bending force of steel products and to detect imperfections in welded joints. The test consists…
Impact strength is the resistance of a material to cracking under dynamic load. The test temperature is an important factor in the impact tests. We perform impact tests at room temperature, at temperatures down to -60oC and at the temperature…
Hardness test consists in deforming the surface of the specimen with a suitable indenter, followed by a measurement of the resulting imprint, which varies in size depending on the material. The most common methods of hardness testing are Vickers, Rockwell…
The fracture test is performed to observe the fracture in terms of the size and distribution of welding imperfections. We perform a breaking test on a testing machine, gradually loading the welded joint until it breaks. This test is particularly…
We perform the chemical composition analysis of the steel on a mobile or stationary OES spark spectrometers. This method consists in exciting the tested material with the spark, and the subsequent analysis of the obtained spectrum of radiation. Our testing…
Corrosion tests are performed to find out how a given metal or welded joint behaves if exposed to a corrosive environment. Corrosion tests are performed in compliance with: ASTM G48 ASTM A262 NORSOK M-601 PN-EN ISO 3651-1 PN-EN ISO 3651-2…
From the constructor’s point of view, the ferrite content is an important feature of steel materials. Too low or too high ferrite content can affect the properties of materials, such as strength, corrosion resistance or weld cracking at high temperatures…
Our test offer according to PN-EN 1090-2 standard includes: examination the usefulness of thermal cutting process examination the usefulness of flame straightening geometric measurements of holes
Roughness measurements are performed with specially designed device. Roughness is one of the important characteristics of metal surfaces, especially when the tested elements have previously been subjected to mechanical or thermal treatment (e.g. thermal cutting). The roughness test allows to…
