Foreword

This foreword is not part of AWS B2.2/B2.2M:2010, Specification for Brazing Procedureand Performance Qualification, but is included for informational purposes only.

The AWS B2 Committee on Procedure and Performance Qualification was formed in 1979. The first edition of B2.1,Standard for Welding Procedure and Performance Qualification, was published in 1984. This standard introduced theconcept of Standard Welding Procedure Specifications (SWPSs) in addition to a set of rules for qualifying weldingprocedures, welders, and welding operators. The following edition, renamed B2.1:1998, Specification for WeldingProcedure and Performance Qualification, was an extensive revision of B2.1-84. The Committee has published sixty-two Standard Welding Procedure Specifications; B2.2, Specification for Brazing Procedure and Performance Qualifica-tion; B2.3, Specification for Soldering Procedure and Performance Qualification; and B2.4, Specification for WeldingProcedure and Performance Qualification for Thermoplastics.

This is the third edition of AWS B2.2, Specification for Brazing Procedure and Performance Qualification. AWS B2.2was first published in 1985. AWS B2.2-85, Standard for Brazing Procedure and Performance Qualification, was firstrevised in 1991. This edition supersedes B2.2-91 and has renamed the standard. Also incorporated into this standard arefour amendments correcting 4.3.11.2 to require a minimum overlap, standardizing the magnification requirements formacroetch tests in 4.2.5.1 and 5.3.3.2, and clarifying verbiage for visual examination in 5.2.1. Underlined text in clauses,tables, or figures indicates an editorial or technical change from the 1991 edition. A vertical line in the margin also indicatesa revision from the 1991 edition.

This standard originated in the B2A Subcommittee on Brazing Qualification. The B2A Subcommittee was formed in theearly 1980s in order to explicitly address the unique requirements of brazing procedure and brazing performance qualifi-cation outside the spectrum of B2.1, Specification for Welding Procedure and Performance Qualification.

Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary,AWS B2 Committee on Procedure and Performance Qualification, American Welding Society, 550 N.W. LeJeune Road,Miami, FL 33126.

1. ScopeThis specification provides the requirements for qualification of Brazing Procedure Specifications (BPSs). This specifi-cation also provides requirements for the performance qualification of brazers and brazing operators. This specificationis intended for use where referenced by a product standard or contract document.

Employers shall be responsible for the brazing done by their organization, including the use of qualified brazing pro-cedures, qualified brazers, and qualified brazing operators. It is the Employer’s responsibility to assure that BrazingProcedure Specifications meet any additional requirements of the Referencing Document. Each Employer shall maintainthe applicable Brazing Procedure Specifications, Brazing Procedure Qualification Records (BPQRs), and Brazing Per-formance Qualification Records during the period of their use.

When not otherwise specified by the Referencing Document, the edition of this specification to be used shall be estab-lished in accordance with the following: (1) editions may be used at any time after the effective date of issue; (2) the latestedition of this document should be used for new contracts; (3) editions established by contract date may be used during theentire term of the contract, or the provisions of later editions may be used when agreed upon by the contracting parties.

This document is intended primarily for use with the following brazing processes:

(1) Torch Brazing (TB)

(2) Furnace Brazing (FB)

(3) Induction Brazing (IB)

(4) Resistance Brazing (RB)

(5) Dip Brazing (DB)

(6) Infrared Brazing (IRB)

(7) Diffusion Brazing (DFB)

This standard makes use of both U.S. Customary Units and the International System of Units (SI). The latter are shownwithin brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents;therefore, each system must be used independently.

Safety and health issues and concerns are beyond the scope of this standard and therefore are not fully addressed herein.Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Weld-ing, Cutting, and Allied Processes, and applicable federal, state, and local regulations.

1.1 Base Metals. The grouping of base metals by Base Metal Number (BM No.) in Table B.1 has been made on the basisof metallurgical compatibility, chemical composition, and brazeability to decrease the number of required brazing quali-fications. The grouping does not imply that base metals may be indiscriminately substituted within the same BM No.without consideration of their applicability. For some materials or combinations of materials, additional tests may berequired by the procuring activity, the Referencing Document, or the design engineer.

Specification for Brazing Procedureand Performance Qualification

AWS B2.2/B2.2M:2010

Base metals are identified by their American Society for Testing and Materials (ASTM), American Bureau of Shipping(ABS), or Unified Numbering System (UNS) designations. Cross reference specifications, listed in the Unified Number-ing System for Metals and Alloys opposite a given UNS No., are included in the same BM No. group as the given UNSNo. An American Society of Mechanical Engineers (ASME) designation, which is the same as an ASTM designationpreceded by the letter S, is included in the same BM No. group.

Eight categories are included as follows:

(1) Ferrous metals (BM Nos. 100 through 180)

(2) Aluminum and aluminum alloys (BM Nos. 200 through 220)

(3) Copper and copper alloys (BM Nos. 300 through 360)

(4) Nickel and nickel alloys (BM Nos. 400 through 420)

(5) Titanium and titanium alloys (BM No. 500)

(6) Zirconium and zirconium alloys (BM No. 600)

(7) Magnesium alloys (BM No. 700)

(8) Cobalt alloys (BM No. 800)

1.2 Filler Metals. The grouping of filler metals by Filler Metal Number (FM No.) in Table C.1 has been made on thebasis of chemical composition to decrease the number of required brazing qualifications. The grouping does not implythat filler metals may be indiscriminately substituted within the same FM No. without consideration of their applicabil-ity. AWS A5.8/A5.8M, Specification for Filler Metals for Brazing and Braze Welding, provides detailed requirementsand general applicability of filler metals.

Filler metals other than those listed in AWS A5.8/5.8M may be used provided such filler metal meets the qualificationrequirements of this specification. For such filler metals, the term “special” shall be listed on the BPS and BPQR in lieuof an FM No.

2. Normative References

4.1 GeneralA brazing procedure qualification provides test data for assessing the properties of a brazed joint. It is the obligation ofmanufacturers to produce brazements that have properties suitable for the application. The proof of production brazesoundness is determined by the type and extent of testing and examination applied, which is the responsibility of theReferencing Document.

4.1.1 The Employer shall determine the appropriate test assembly to be used to make a test brazement.

4.1.1.1 To qualify a brazing procedure, the following steps are necessary.

(1) Any format may be used for the BPS, provided all qualification variables and other applicable information areincluded.

(2) The actual conditions used in making the test brazement and the results of the required examination and specimentesting shall be recorded on a Brazing Procedure Qualification Record (BPQR). Any format may be used, provided allqualification variables are addressed.

(3) The qualifying company shall certify that the information on the BPQR is an accurate record of the testsperformed and the test results are in compliance with the qualification variables and testing requirements of AWSB2.2/B2.2M, Specification for Brazing Procedure and Performance Qualification.

(4) If the results do not meet acceptance requirements, a new test brazement shall be prepared. Test brazements shallnot be repaired.

(5) Procedures qualified by one Employer are not transferable to another Employer.

4.1.2 During the making of procedure test brazements for qualification, the brazer or brazing operator shall be underthe full supervision and control of the Qualifier. The Qualifier is responsible for assuring proper:

(1) Preparation of workpieces for brazing

(2) Documentation of the test brazing variables

(3) Preparation of specimens from the completed brazement

(4) Performance of examination and mechanical tests

(5) Documentation of results

4.1.3 A change in any brazing variable beyond the limits of 4.3 Qualification Variables shall require preparation of anew or revised BPS supported by one or more BPQRs. Changes in variables within the limits of 4.3 do not requirerequalification provided the BPS is revised to address the new brazing variables or conditions.

4.1.4 BPQRs shall not be revised except to correct errors or add omitted information. All revised changes shall beidentified and dated on the BPQR.

4.1.5 The identification of the BPQR(s) that support the BPS shall be recorded on the BPS.

4.1.6 A BPS may require the support of more than one BPQR, while alternatively, one BPQR may support a numberof BPSs.

4.2.3.2 For lap joints, spliced butt joints, and rabbet joints in plate or pipe greater than 3 in [75 mm] OD, tensionspecimens shall be prepared as shown in Figure A.2C. Specimens shall be tested with no restraining device to preventdistortion. Where a peel test with a flanged member is substituted for the macroetch test, as described in 4.2.6, thetension specimen shall be tested without removal of the flanges.

4.2.3.3 For pipe and tubes with an outside diameter greater than 3 in [75 mm], tension specimens as shown inFigure A.2A or A.2B, except for the curvature of the specimen transverse axis, shall be tested with no restraining deviceto prevent distortion during testing. Where a peel test with a flanged member is substituted for the macroetch test, asdescribed in 4.2.6, the tension specimen shall be tested without removal of the flanges.

4.2.3.4 For pipe and tubes with an outside diameter of 3 in [75 mm] or less, a tension specimen consisting of alength of the entire joint shall be tested as shown in Figure A.2D.

4.2.3.5 Acceptance Criteria for Butt Joints. The specimen shall have a minimum tensile strength not less thanshown in Table B.1 or as established by the Referencing Document.

4.2.3.6 Acceptance Criteria for Lap Joints, Spliced Butt Joints, and Rabbet Joints. The specimen shall have atensile strength not less than 95% of the minimum tensile strength of the base metal. If this minimum tensile strength isnot given in Table B.1, it shall be established in the Referencing Document. The tensile strength of the specimen shallbe computed by dividing the ultimate load by the cross-sectional area of the base metal. For dissimilar metal joints thedivisor shall be the cross-sectional area of the joint member where the failure occurred.

4.2.4 Bend Test. The cutting plan for the blanks for the bend specimens from standard test brazements is shown inFigures 4.1 and 4.4. Figure 4.4 applies to pipe and tubes of all diameters.

The blanks shall be 1-1/2 in [38 mm] in width; except that for pipe and tube with anoutside diameter of 3 in [75 mm] or less, the blanks shall be two opposing quadrants.

4.2.5.1 Both sides of each blank shall be smoothed and, if necessary, etched with a suitable reagent to give a cleardefinition of the braze metal. Each surface shall be examined with at least a four-power magnifying glass.

4.2.5.2 Acceptance Criteria for Macroetch Tests. None of the cross sections, when considered individually, shallhave a total length of discontinuities; such as pores, voids, unbrazed areas, or inclusions, greater than 20% of any singlelap length. No cracks shall be present in the brazed joint or in the base metal.

Annex B (Normative)

Base Metal GroupsThis annex is part of AWS B2.2/B2.2M:2010, Specification for Brazing Procedure andPerformance Qualification, and includes mandatory elements for use with this standard.

B1. Base Metal NumbersBase metals have been grouped by Base Metal Number (BM No.) in Table B.1 so that the required number of qualifica-tions may be reduced. Substitution of one base metal for another, for any purpose other than for qualification, even whenwithin the allowable rules, should be made only after an evaluation of all the factors involved.

B2. Basis for Classification of Base Metals for Brazing QualificationB2.1 General

B2.1.1 Where classification is dependent on the amount of a given element, the controlling value is the maximumcontent given in the base metal specification.

B2.1.2 The tensile strength is for the annealed condition. Where the minimum tensile strength is not given in TableB.1, that value shall be established by the Referencing Document.

B2.2 Ferrous Alloys. The base metal numbers for ferrous alloys are listed below:

BM No.

100 Steels containing 1% or less chromium

110 Steels containing more than 1% chromium. See (1) below.

120 Steels containing aluminum or titanium

130 Stainless steels, austenitic

140 Stainless steels, austenitic containing titanium of less than 0.3%

150 Stainless steels, martensitic, and ferritic

160 Stainless steels, martensitic, and ferritic containing less than 0.3% combined aluminum and titanium

170 Cast iron

180 Cast iron, austenitic

(1) Steels with 12% or greater chromium are included in stainless steels.

(2) Where the tensile strength given in the specification is dependent on base metal thickness, the strength given inTable B.1 is the value for the thickest base metal, up to a limit of 1 in [25 mm].

Annex C (Normative)

Filler Metal GroupsThis annex is part of AWS B2.2/B2.2M:2010, Specification for Brazing Procedure andPerformance Qualification, and includes mandatory elements for use with this standard.

C1. Filler metals have been grouped by Filler Metal Number (FM No.) in Table C.1 so that the required number of qual-ifications may be reduced. Substitution of one filler metal for another, for any purpose other than for qualification, evenwhen permitted by the rules, should be made only after an evaluation of all the factors involved.

C2. The chemical compositions in Table C.1 are approximate. For accurate values see the latest edition of AWSA5.8/A5.8M, Specification for Filler Metals for Brazing.

C3. The solidus and liquidus temperatures are listed for information only.

Annex G (Informative)

Guidelines for the Preparation of Technical Inquiries

This annex is not part of AWS B2.2/B2.2M:2010, Specification for Brazing Procedureand Performance Qualification, but is included for informational purposes only.

G1. Introduction

The AWS Board of Directors has adopted a policy whereby all official interpretations of AWS standards will be handledin a formal manner. Under that policy, all interpretations are made by the committee that is responsible for the standard.Official communication concerning an interpretation is through the AWS staff member who works with that committee.The policy requires that all requests for an interpretation be submitted in writing. Such requests will be handled as expe-ditiously as possible but due to the complexity of the work and the procedures that must be followed, some interpretationsmay require considerable time.

G2. Procedure

All inquiries must be directed to:

Managing Director, Technical Services

American Welding Society

550 N.W. LeJeune Road

Miami, FL 33126

All inquiries must contain the name, address, and affiliation of the inquirer, and they must provide enough informationfor the committee to fully understand the point of concern in the inquiry. Where that point is not clearly defined, theinquiry will be returned for clarification. For efficient handling, all inquiries should be typewritten and should also be inthe format used here.

G2.1 Scope. Each inquiry must address one single provision of the standard, unless the point of the inquiry involves twoor more interrelated provisions. That provision must be identified in the scope of the inquiry, along with the edition ofthe standard that contains the provisions or that the inquirer is addressing.

G2.2 Purpose of the Inquiry. The purpose of the inquiry must be stated in this portion of the inquiry. The purpose canbe either to obtain an interpretation of a standard requirement, or to request the revision of a particular provision in thestandard.

G2.3 Content of the Inquiry. The inquiry should be concise, yet complete, to enable the committee to quickly and fullyunderstand the point of the inquiry. Sketches should be used when appropriate and all paragraphs, figures, and tables (orthe Annex), which bear on the inquiry must be cited. If the point of the inquiry is to obtain a revision of the standard, theinquiry must provide technical justification for that revision.

G2.4 Proposed Reply. The inquirer should, as a proposed reply, state an interpretation of the provision that is the pointof the inquiry, or the wording for a proposed revision, if that is what inquirer seeks.

AWS B2.2/B2.2M:2010

68

G3. Interpretation of Provisions of the StandardInterpretations of provisions of the standard are made by the relevant AWS Technical Committee. The secretary of thecommittee refers all inquiries to the chairman of the particular subcommittee that has jurisdiction over the portion of thestandard addressed by the inquiry. The subcommittee reviews the inquiry and the proposed reply to determine what theresponse to the inquiry should be. Following the subcommittee’s development of the response, the inquiry and theresponse are presented to the entire committee for review and approval. Upon approval by the committee, the interpreta-tion will be an official interpretation of the Society, and the secretary will transmit the response to the inquirer and to theWelding Journal for publication.

G4. Publication of InterpretationsAll official interpretations shall appear in the Welding Journal and shall be posted on the AWS website.

G5. Telephone InquiriesTelephone inquiries to AWS Headquarters concerning AWS standards should be limited to questions of a general natureor to matters directly related to the use of the standard. The Board of Directors’ policy requires that all AWS staff mem-bers respond to a telephone request for an official interpretation of any AWS standard with the information that such aninterpretation can be obtained only through a written request. The Headquarters staff cannot provide consulting services.The staff can, however, refer a caller to any of those consultants whose names are on file at AWS Headquarters.

G6. The AWS Technical CommitteeThe activities of AWS Technical Committees in regard to interpretations, are limited strictly to the Interpretation of pro-visions of standards prepared by the committee or to consideration of revisions to existing provisions on the basis of newdata or technology. Neither the committee nor the staff is in a position to offer interpretive or consulting services on: (1)specific engineering problems, or (2) requirements of standards applied to fabrications outside the scope of the docu-ment or points not specifically covered by the standard. In such cases, the inquirer should seek assistance from a compe-tent engineer experienced in the particular field of interest.
