Raumfahrtproduktsicherung - Prozess- und Qualitätssicherungsanforderungen für das Hartlöten von Metallen für Flughardware
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.
Assurance produit des projets spatiaux - Exigences de traitement et d'assurance qualité pour le brasage fort de matériaux métalliques pour matériel de vol
La présente norme spécifie les exigences relatives au traitement et à l'assurance qualité des procédés de brasage destinés aux applications de vol spatial. Le brasage s’entend comme l’assemblage et le scellement de matériaux au moyen d’une solidification d’un métal d’apport liquide.
Dans la présente norme, le terme « brasage » est utilisé comme regroupant les notions de « brasage fort » (brazing en anglais) et « brasage tendre » (soldering), pour le cas des matériaux d'apport qui ont des températures de liquidus en dessous de 450 °C.
Le brasage fort et le brasage tendre sont des techniques connexes au soudage (welding) et la présente norme vient en complément de la norme ECSS-Q-ST-70-39 relative au soudage.
La présente norme ne couvre pas les exigences relatives :
• aux procédés d'assemblage par collage adhésif (ECSS-Q-ST-70-16) ;
• au brasage à des fins d’assemblage électronique (ECSS-Q-ST-70-61) ;
• au brasage utilisé dans la fabrication d'hybrides (ESCC 2566000).
La norme couvre, sans toutefois s’y limiter, les procédés de brasage suivants :
• brasage fort aux gaz ;
• brasage fort au four ;
• brasage fort au trempé et brasage fort au bain de sel ;
• brasage fort par induction.
La présente norme ne donne pas de détails sur les phases de définition et de pré-vérification du brasage, y compris les écarts de conception autorisés.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d'un projet spatial conformément à l'ECSS-S-ST-00.
Zagotavljanje kakovosti proizvodov v vesoljski tehniki - Zahteve za obdelavo in zagotavljanje kakovosti za trdo spajkanje kovinskih materialov za letalsko strojno opremo
Ta standard določa zahteve za obdelavo in zagotavljanje kakovosti za postopke trdega spajkanja za načine uporabe pri vesoljskih poletih. Trdo spajkanje se razume kot spajanje in tesnjenje materialov s strjevanjem tekočega kovinskega polnila.
Izraz trdo spajkanje se v tem standardu uporablja kot enakovreden izraz spajkanje v primerih, ko je temperatura tališča polnilnih materialov pod 450 °C.
Trdo spajkanje in spajkanje sta sorodna postopka varjenju, zato ta standard dopolnjuje standard za varjenje ECSS-Q-ST-70-39.
Ta standard ne zajema zahtev za:
• postopke spajanja z lepljenjem (ECSS-Q-ST-70-16),
• spajkanje za namene elektronskega sestava (ECSS-Q-ST-70-61),
• spajkanje v hibridni proizvodnji (ESCC 2566000).
Standard med drugim obravnava naslednje postopke trdega spajkanja:
• plamensko spajkanje,
• spajkanje v peči,
• potopno spajkanje in spajkanje s solno kislino,
• indukcijsko spajkanje.
Ta standard ne opisuje faze opredelitve trdega spajkanja in faze predhodnega preverjanja trdega spajkanja, vključno z izpeljavo zasnovnih dopustnih vrednosti.
Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
