Qualification for Brazing

Mathias Lundin, Swedish Welding Commission


Activities to controll

= Tasks

  • Operating procedures

  • Documentation

  • Testing, storage and handling of bra-zing consumables and parent material

  • Heat treatment

  • Inspection prior, during and post brazing

  • Non-conformance and corrective actions

  • Calibration and validation

  • Identification and traceability

  • Quality records

  • Review of requirements

  • Technical review

  • Sub-contracting

  • Brazers and operators

  • Brazing coordination

  • Inspection and testing personnel

  • Production equipment

  • Maintenance of equipment

  • Production planning

  • Brazing procedure specifications (BPS)

  • Qualification of brazing procedures


Qualification of brazing personnel

ISO 13585Brazing — Qualification test of brazers and brazing operators

”brazer ability to by hand manipulate the device for heating following a specification to reproduce a braze joint with acceptable quality”

”operator ability to follow a specification to reproduce a braze joint with acceptable quality”

Essential variables => Range of qualification

Key elements

  • Standardized test pieces

  • Essential variables

  • Ranges of qualification

  • Requirements for testing

  • Acceptance criteria

  • Requirements for validity

  • Requirements for certificate

  • brazingprocess

  • producttype

  • typeof joint

  • parent material group(s)

  • brazing filler metal type

  • brazing filler application

  • dimension (material thickness, outsidepipe diameter and overlaplength)

  • filler metal flowdirection

  • degreeofmechanization

ISO/FDIS 13585


Qualification of brazing procedures

ISO/PWI xxxxxBrazing – Qualification and specification of brazing procedures

(revision of EN 13134)

Verifying joint properties

”special process – since joint properties and integrity can not be fully verified with NDT after brazing, a procedure needs to be qualified and reproduced during production”

Essential variables/range of qualification – different compared to personnel

brazing process

parent material group

brazing filler and flux

dimensions

working temperature

etc


pBPS

Braze test (brazing of standardized test piece)

Verifing tests + evaluation(visual testing, NDT, destructive testing)

Brazing Procedure Qualification Record (BPQR)
