This document may be used for the electron beam welding (process no. 51 according to EN ISO 4063) of weldable metallic materials according to CR ISO 15608. It does not contain data on permissible stresses on weld seams or on the testing and evaluation of weld seams. Such data can either be seen from the relevant user documents or should be separately agreed between the contracting parties.A requirement for the application of this document is that the recommendations should be used by appropriately trained and experienced personnel.
