Certification of the Thermal Cutting process: essential requirements

The certification of the thermal cutting process is a crucial phase in the production of metal structures, requiring the careful execution of representative samples according to precise regulatory specifications.

According to Appendix D of EN 1090-2 and EN ISO 9013, this process requires the execution of samples that meet specific geometric and thickness parameters to ensure their suitability for structural use.

  • Reference standards: Appendix D of EN 1090-2 and EN ISO 9013
  • Certification requirements: EN 1090-2, in Appendix D, figure D.1, specifies the requirements for the certification of the thermal cutting process. These include the creation of two thermal cutting samples, one with the minimum thickness and one with the maximum thickness, with defined geometries and dimensions.
  • Coverage: to ensure accurate certification, holes of different diameters must be made in each sample to cover a representative range of operating conditions. These include the hole with the smallest diameter and the one with the largest diameter.
  • Validity fields of the certificate: execution class according to EN 1090-2, the process and type of cutting employed, the group and subgroup of the base material, the material thickness, as well as various operational parameters such as the heating oxygen pressure, cutting speed, and preheating temperature.
