| Nosaukums | This standard will establish the processing and quality assurance requirements for different types of brazing treatment for space flight applications. This standard will be applicable to all Projects and Programmes where brazing treatments activities are performed. The document is intended to be used by PA Managers, Project Managers, Engineers and those involved with manufacturing. Few international standards which relate to brazing treatments of metallic materials are readily available. A few of these are dedicated towards aeronautic applications which are currently used for space applications. Moreover, it is common to encounter the use of aircraft manufacturer standards (Boeing, Airbus) in Space Industry. However, experience demonstrates that on a regular basis, there are significant differences among the various standards, which lead to variations in the interpretation of the standards from one to another. At the same, there is a lack of information concerning specific brazing systems: e.g. ceramic/ceramic or ceramic/metals. As a consequence, Space Industries are using their own standards to improve reproducibility of brazing processes. Moreover, because there is no single high level ECSS standard on brazing processes, it has also been discovered on a number of occasions that processes are partially qualified, or if a qualification has been performed, it is not to a known standard. Moreover, during manufacturing, a clear definition and implementation of brazing treatment quality monitoring and control means is often not present. By developing a single high level ECSS standard which can be tailored in the Project definition phase, it will help all project actors in performing the following functions related to brazing processes which shall be considered as a very critical Special Process: (i) select and verify equipment (furnaces, induction, flame, bath), atmosphere, temperature (control & uniformity), (ii) Verify the whole brazing treatment sequences including cleaning and etching, (iii) determine the acceptance criteria for imperfections in brazed joint (iv) define monitoring and control means during production to ensure that brazing processes are reproducible and produced with the required quality, (v) define rules for applying Test and Inspection methods This will significantly reduce the number of partially-verified brazing treatment processes and also reduce the number of occasions when parts are delivered to the customer which do not conform to the required specification. |
