Testing the Quality of CNC Plasma Thermal Cutting in Accordance with the HRN EN 1090-2 Standard for the Production of Steel Structures
摘要
The paper briefly explains the development of the EN 1090 standard through the theoretical part where the general data of the standard is presented, and in the practical part one of the requirements of the standard is analyzed where its application to thermal cutting of steel sheets is shown. It is necessary to provide a standard in which the basic characteristics of the semi-finished product (microstructure of the material) are changed only up to the permitted limits, because changes greater than the permitted greatly affect the behavior of the components during the next steps in the production process.
