Additional Requirements Concerning the Fabrication of Welded Structures in Accordance with the EN 1090 Standard

Jakub Kozłowski, Ryszard Krawczyk

The manufacturer of welded structures should meet the requirements set forth in the EN 1090 standard, concerning, in particular, technological processes as well as their control and supervision. Additional requirements are concerned with the selection and evaluation of structural material properties. The so-called Z-test enables the assessment of plastic properties in the direction perpendicular to the material surface, whereas test SEP 1390 is used to evaluate the weldability of thick-walled materials (based on material ability to block the development of initiated cracks). These additional requirements aim to increase the safety and service life of crucial welded structures exposed to dynamic loads.
