This summary guide, written by the COFREND Additive Manufacturing working group, is aimed at industrial NDT operators who do not yet have sufficient control over the processes of additive manufacturing. Its work focuses on the DED (Directed Energy Deposition) and PBF (Powder Bed Fusion) processes. The DED process includes wire arc.
Volume 1 consists of three chapters
- Chapter 1 : a complete review of the state of the art of standardization and the proposals intended to speed up the production of ISO/ASTM standards dedicated to the NDT of metal parts produced by AM. These proposals consider the existing structure of ISO standardization for welding and casting. The standards that could act as a starting point were identified, as well as the development priorities. This work is being carried out in collaboration with UNM 920, which is the entity that represents France in the preparation of ISO/ASTM standards.
- Chapter 2 : a proposal for the classification of the imperfections likely to be produced in wire arc DED.
- Chapter 3 : a proposal for the classification of the imperfections likely to be produced in PBF.
