Edition date: 2021-12-21
In Force
Available languages: English, French
Summary:

This document specifies requirements for the specification and qualification of brazing procedures for brazing of metallic materials.

This document specifies requirements for brazing of the test piece, testing of the test specimen, essential variables and their range of qualification, acceptance criteria, brazing procedure qualification record (BPQR) and brazing procedure specification (BPS).

This document gives general provisions on quality requirements for brazing (see Annex A).

This document does not cover testing of residual stresses, corrosion resistance and impact properties.

This document applies to the following brazing processes according to ISO 857-2 and ISO 4063:2009 with local and global heating:

—    911 Infrared brazing;

—    912 Flame brazing, torch brazing;

—    913 Laser beam brazing;

—    914 Electron beam brazing;

—    916 Induction brazing;

—    918 Resistance brazing;

—    919 Diffusion brazing;

—    921 Furnace brazing;

—    922 Vacuum brazing;

—    923 Dip-bath brazing;

—    924 Salt-bath brazing;

—    925 Flux bath brazing;

—    926 Immersion brazing;

—    972 Arc weld brazing.

The principles of this document can be applied to other brazing processes and brazing of materials not listed.



Le présent document spécifie les exigences relatives à la spécification et à la qualification des modes opératoires de brasage fort pour les matériaux métalliques.

Le présent document spécifie les exigences pour le brasage fort de l’assemblage de qualification, les essais de l’éprouvette, les variables essentielles et leur domaine de validité, les critères d’acceptation, le procès-verbal de qualification du mode opératoire de brasage fort (PV-QMOB) et le descriptif de mode opératoire de brasage fort (DMOB).

Le présent document donne des dispositions générales sur les exigences de qualité pour le brasage fort (voir Annexe A).

Le présent document ne traite pas des essais portant sur les contraintes résiduelles, la résistance à la corrosion et la résistance à la flexion par choc.

Le présent document s’applique aux procédés de brasage fort suivants, conformes à l’ISO 857-2 et à l’ISO 4063:2009, avec chauffage local et global:

—    911 Brasage fort par infrarouge;

—    912 Brasage fort à la flamme, brasage fort au chalumeau;

—    913 Brasage fort par faisceau laser;

—    914 Brasage fort par faisceau électronique;

—    916 Brasage fort par induction;

—    918 Brasage fort par résistance;

—    919 Brasage fort par diffusion;

—    921 Brasage fort au four;

—    922 Brasage fort sous vide;

—    923 Brasage fort au trempé;

—    924 Brasage fort au bain de sel;

—    925 Brasage fort en bain de flux;

—    926 Brasage fort par immersion;

—    972 Soudobrasage à l’arc.

Les principes du présent document peuvent s'appliquer à d'autres procédés de brasage fort et au brasage de matériaux qui ne figurent pas dans la liste.

Le présent document ne s’applique pas au brasage fort pour les applications aérospatiales couvertes par l’ISO 11745.
