FOREWORD

The American Society of Mechanical Engineers setup a committee in 1911 for the purpose of formulatingstandard rules for the construction of steam boilers andother pressure vessels. This committee is now calledthe Boiler and Pressure Vessel Committee.

The Committee’s function is to establish rules ofsafety governing the design, fabrication, and inspectionduring construction of boilers and pressure vessels, andto interpret these rules when questions arise regardingtheir intent. In formulating the rules, the Committeeconsiders the needs of users, manufacturers, and inspec-tors of pressure vessels. The objective of the rules isto afford reasonably certain protection of life andproperty and to provide a margin for deterioration inservice so as to give a reasonably long, safe periodof usefulness. Advancements in design and materialand the evidence of experience have been recognized.

This Code contains mandatory requirements, specificprohibitions, and nonmandatory guidance for construc-tion1 activities. The Code does not address all aspectsof these activities and those aspects which are notspecifically addressed should not be considered prohib-ited. The Code is not a handbook and cannot replaceeducation, experience, and the use of engineering judg-ment. The phraseengineering judgmentrefers to techni-cal judgments made by knowledgeable designers experi-enced in the application of the Code. Engineeringjudgments must be consistent with Code philosophyand such judgments must never be used to overrulemandatory requirements or specific prohibitions ofthe Code.

The Committee recognizes that tools and techniquesused for design and analysis change as technologyprogresses and expects engineers to use good judgmentin the application of these tools. The designer is respon-sible for complying with Code rules and demonstratingcompliance with Code equations when such equationsare mandatory. The Code neither requires nor prohibitsthe use of computers for the design or analysis ofcomponents constructed to the requirements of theCode. However, designers and engineers using computer

1 Construction, as used in this Foreword, is an all-inclusive termcomprising materials, design, fabrication, examination, inspection,testing, certification, and pressure relief.

ix

programs for design or analysis are cautioned that theyare responsible for all technical assumptions inherentin the programs they use and they are responsible forthe application of these programs to their design.

The Code does not fully address tolerances. Whendimensions, sizes, or other parameters are not specifiedwith tolerances, the values of these parameters areconsidered nominal and allowable tolerances or localvariances may be considered acceptable when basedon engineering judgment and standard practices asdetermined by the designer.

The Boiler and Pressure Vessel Committee dealswith the care and inspection of boilers and pressurevessels in service only to the extent of providingsuggested rules of good practice as an aid to ownersand their inspectors.

The rules established by the Committee are not tobe interpreted as approving, recommending, or endors-ing any proprietary or specific design or as limitingin any way the manufacturer’s freedom to choose anymethod of design or any form of construction thatconforms to the Code rules.

The Boiler and Pressure Vessel Committee meetsregularly to consider revisions of the rules, new rulesas dictated by technological development, Code Cases,and requests for interpretations. Only the Boiler andPressure Vessel Committee has the authority to provideofficial interpretations of this Code. Requests for revi-sions, new rules, Code Cases, or interpretations shallbe addressed to the Secretary in writing and shall givefull particulars in order to receive consideration andaction (see Mandatory Appendix covering preparationof technical inquiries). Proposed revisions to the Coderesulting from inquiries will be presented to the MainCommittee for appropriate action. The action of theMain Committee becomes effective only after confirma-tion by letter ballot of the Committee and approval byASME.

Proposed revisions to the Code approved by theCommittee are submitted to the American NationalStandards Institute and published inMechanical Engi-neeringto invite comments from all interested persons.After the allotted time for public review and final

approval by ASME, revisions are published annuallyin Addenda to the Code.

Code Cases may be used in the construction ofcomponents to be stamped with the ASME Code symbolbeginning with the date of their approval by ASME.

After Code revisions are approved by ASME, theymay be used beginning with the date of issuance shownon the Addenda. Revisions, except for revisions tomaterial specifications in Section II, Parts A and B,become mandatory 6 months after such date of issuance,except for boilers or pressure vessels contracted forprior to the end of the 6 month period. Revisions tomaterial specifications are originated by the AmericanSociety for Testing and Materials (ASTM), and otherrecognized national or international organizations andare usually adopted by ASME. However, those revisionsmay or may not have any effect on the suitability ofmaterial, produced to earlier editions of specifications,for use in ASME construction. ASME material specifi-cations approved for use in each construction Code arelisted in the Appendices of Section II, Parts A and B.These Appendices list, for each specification, the latestedition adopted by ASME, and earlier and later editionsconsidered by ASME to be identical for ASME con-struction.

Manufacturers and users of components are cautionedagainst making use of revisions and Cases that are lessrestrictive than former requirements without havingassurance that they have been accepted by the properauthorities in the jurisdiction where the component isto be installed.

Each state and municipality in the United States andeach province in Canada that adopts or accepts one ormore Sections of the Boiler and Pressure Vessel Codeis invited to appoint a representative to act on theConference Committee to the Boiler and Pressure VesselCommittee. Since the members of the Conference Com-mittee are in active contact with the administration andenforcement of the rules, the requirements for inspectionin this Code correspond with those in effect in theirrespective jurisdictions. The required qualifications foran Authorized Inspector under these rules may beobtained from the administrative authority of any state,municipality, or province which has adopted these rules.

The Boiler and Pressure Vessel Committee in theformulation of its rules and in the establishment ofmaximum design and operating pressures considersmaterials, construction, methods of fabrication, inspec-tion, and safety devices. Permission may be grantedto regulatory bodies and organizations publishing safetystandards to use a complete Section of the Code byreference. If usage of a Section, such as Section IX,

x

involves exceptions, omissions, or changes in provisions,the intent of the Code might not be attained.

Where a state or other regulatory body, in the printingof any Section of the Boiler and Pressure Vessel Code,makes additions or omissions, it is recommended thatsuch changes be clearly indicated.

The National Board of Boiler and Pressure VesselInspectors is composed of chief inspectors of statesand municipalities in the United States and of provincesin Canada that have adopted the Boiler and PressureVessel Code. This Board, since its organization in 1919,has functioned to uniformly administer and enforce therules of the Boiler and Pressure Vessel Code. Thecooperation of that organization with the Boiler andPressure Vessel Committee has been extremely helpful.

The Code Committee does not rule on whether acomponent shall or shall not be constructed to theprovisions of the Code. The Scope of each Sectionhas been established to identify the components andparameters considered by the Committee in formulatingthe Code rules. Laws or regulations issued by municipal-ity, state, provincial, federal, or other enforcement orregulatory bodies having jurisdiction at the location ofan installation establish the mandatory applicability ofthe Code rules, in whole or in part, within theirjurisdiction. Those laws or regulations may require theuse of this Code for vessels or components not consid-ered to be within its Scope or may establish additions ordeletions in that Scope. Accordingly, inquiries regardingsuch laws or regulations are to be directed to theissuing enforcement or regulatory body.

Questions or issues regarding compliance of a specificcomponent with the Code rules are to be directed tothe ASME Certificate Holder (Manufacturer). Inquiriesconcerning the interpretation of the Code are to bedirected to the ASME Boiler and Pressure VesselCommittee. ASME is to be notified should questionsarise concerning improper use of an ASME Codesymbol.

The specifications for materials given in Section IIare identical with or similar to those of the Specificationspublished by ASTM, AWS, and other recognized na-tional or international organizations. When reference ismade in an ASME material specification to a non-ASME specification for which a companion ASMEspecification exists, the reference shall be interpretedas applying to the ASME material specification. Notall materials included in the material specifications inSection II have been adopted for Code use. Usage islimited to those materials and grades adopted by atleast one of the other Sections of the Code for applica-tion under rules of that Section. All materials allowedby these various Sections and used for construction

within the scope of their rules shall be furnished inaccordance with material specifications contained inSection II or referenced in Appendices A of SectionII, Parts A and B except where otherwise provided inCode Cases or in the applicable Section of the Code.Materials covered by these specifications are acceptablefor use in items covered by the Code Sections onlyto the degree indicated in the applicable Section. Materi-als for Code use should preferably be ordered, produced,and documented on this basis; Appendix A to SectionII, Part A and Appendix A to Section II, Part B listeditions of ASME and year dates of specifications thatmeet ASME requirements and which may be used inCode construction. Material produced to an acceptablespecification with requirements different from the re-quirements of the corresponding specifications listed in

xi

Appendix A of Part A or Part B may also be usedin accordance with the above, provided the materialmanufacturer or vessel manufacturer certifies with evi-dence acceptable to the Authorized Inspector that thecorresponding requirements of specifications listed inAppendix A of Part A or Part B have been met.Material produced to an acceptable material specificationis not limited as to country of origin.

When required by context in this Section, the singularshall be interpreted as the plural, and vice-versa; andthe feminine, masculine, or neuter gender shall betreated as such other gender as appropriate.

Publication of the SI (Metric) Edition of the ASMEBoiler and Pressure Vessel Code was discontinued withthe 1986 Edition. Effective October 1, 1986, the SIEdition was withdrawn as an ASME Boiler and PressureVessel Code document.

STATEMENT OF POLICYON THE USE OF CODE SYMBOLS AND

CODE AUTHORIZATION IN ADVERTISING

ASME has established procedures to authorize quali-fied organizations to perform various activities in ac-cordance with the requirements of the ASME Boilerand Pressure Vessel Code. It is the aim of the Societyto provide recognition of organizations so authorized.An organization holding authorization to perform vari-ous activities in accordance with the requirements ofthe Code may state this capability in its advertisingliterature.

Organizations that are authorized to use Code Symbolsfor marking items or constructions which have been con-structed and inspected in compliance with the ASMEBoiler and Pressure Vessel Code are issued Certificates ofAuthorization. It is the aim of the Society to maintain thestanding of the Code Symbols for the benefit of the users,the enforcement jurisdictions, and the holders of the sym-bols who comply with all requirements.

Based on these objectives, the following policy hasbeen established on the usage in advertising of facsimilesof the symbols, Certificates of Authorization, and refer-ence to Code construction. The American Society ofMechanical Engineers does not “approve,” “certify,”

STATEMENT OF POLICYON THE USE OF ASME MARKING

TO IDENTIFY MANUFACTURED ITEMS

The ASME Boiler and Pressure Vessel Code providesrules for the construction of boilers, pressure vessels, andnuclear components. This includes requirements for mate-rials, design, fabrication, examination, inspection, andstamping. Items constructed in accordance with all of theapplicable rules of the Code are identified with the officialCode Symbol Stamp described in the governing Section ofthe Code.

Markings such as “ASME,” “ASME Standard,” orany other marking including “ASME” or the variousCode Symbols shall not be used on any item which is

xiii

“rate,” or “endorse” any item, construction, or activityand there shall be no statements or implications whichmight so indicate. An organization holding a CodeSymbol and/or a Certificate of Authorization may statein advertising literature that items, constructions, oractivities “are built (produced or performed) or activitiesconducted in accordance with the requirements of theASME Boiler and Pressure Vessel Code,” or “meetthe requirements of the ASME Boiler and PressureVessel Code.”

INTRODUCTION

The following is a brief introduction to the 2001Edition of Section IX and cannot be considered as asubstitute for the actual review of appropriate sectionsof the document. However, this introduction is intendedto give the reader a better understanding of the purposeand organization of Section IX.

Section IX of the ASME Boiler and Pressure VesselCode relates to the qualification of welders, weldingoperators, brazers, and brazing operators, and the proce-dures employed in welding or brazing in accordancewith the ASME Boiler and Pressure Vessel Code andthe ASME B31 Code for Pressure Piping. As such,this is an active document subject to constant review,interpretation, and improvement to recognize new devel-opments and research data. Section IX is a documentreferenced for qualification by various constructioncodes such as Section I, III, IV, VIII, etc. Theseparticular construction codes apply to specific types offabrication and may impose additional welding require-ments or exemptions to Section IX qualifications. Quali-fication in accordance with Section IX is not a guaranteethat procedures and performance qualifications will beacceptable to a particular construction code.

Section IX establishes the basic criteria for weldingand brazing which are observed in the preparation ofwelding and brazing requirements that affect procedureand performance. It is important that the user of the2001 Edition of Section IX understand the basic criteriain reviewing the requirements which have been estab-lished.

The purpose of the Welding Procedure Specification(WPS) and Procedure Qualification Record (PQR) is todetermine that the weldment proposed for construction iscapable of having the required properties for its intendedapplication. It is presupposed that the welder or weldingoperator performing the welding procedure qualificationtest is a skilled workman. This also applies to theBrazing Procedure Specifications (BPS) and the brazerand brazing operator qualifications. The procedure quali-fication test is to establish the properties of the weldmentor brazement and not the skill of the personnel per-forming the welding or brazing. In addition, specialconsideration is given when notch toughness is requiredby other Sections of the Code. The notch-toughness

xxv

variables do not apply unless referenced by the construc-tion codes.

In Welder or Brazer /Brazing Operator PerformanceQualification, the basic criterion is to determine theability to deposit sound weld metal, or to make asound braze. In Welding Operator Performance Qualifi-cation, the basic criterion is to determine the mechanicalability of the welding operator to operate the equipment.

In developing the present Section IX, each weldingprocess and brazing process that was included wasreviewed with regard to those items (called variables)which have an affect upon the welding or brazingoperations as applied to procedure or performancecriteria.

The user of Section IX should be aware of howSection IX is organized. It is divided into two parts:welding and brazing. Each part is then divided intoarticles. These articles deal with the following:

(a) general requirements (Article I Welding and Arti-cle XI Brazing)

(b) procedure qualifications (Article II Welding andArticle XII Brazing)

(c) performance qualifications (Article III Weldingand Article XIII Brazing)

(d) data (Article IV Welding and Article XIVBrazing)

(e) standard welding procedures (Article V Welding)

These articles contain general references and guidesthat apply to procedure and performance qualificationssuch as positions, type and purpose of various mechani-cal tests, acceptance criteria, and the applicability ofSection IX, which was in the Preamble of the 1980Section IX (the Preamble has been deleted). The generalrequirement articles reference the data articles for spe-cifics of the testing equipment and removal of themechanical test specimens.

PROCEDURE QUALIFICATIONSEach process that has been evaluated by Section IX

is listed separately with the essential and nonessentialvariables as they apply to that particular process. Ingeneral, the Welding Procedure Specifications (WPS)and the Brazing Procedure Specifications (BPS) are tolist all essential and nonessential variables for each

A02

process that is included under that particular procedurespecification. If a change is made in any essentialvariable, requalification of the procedure is required.If a change is made in a nonessential variable, theprocedure need only be revised or amended to addressthe nonessential variable change. When notch toughnessis required by the construction code, the supplementaryessential variables become additional essential variablesand a change requires requalification of the procedure.

In addition to covering various processes, there arealso rules for procedure qualification of corrosion-resistant weld metal overlay and hard-facing weld metaloverlay.

Beginning with the 2000 Addenda, the use of Stan-dard Welding Procedure Specifications (SWPSs) waspermitted. Article V provides the requirements andlimitations that govern the use of these documents. TheSWPSs approved for use are listed in Appendix E.

PERFORMANCE QUALIFICATIONSThese articles list separately the various welding and

brazing processes with the essential variables that applyto the performance qualifications of each process. Thewelder, brazer, and brazing operator qualifications arelimited by essential variables.

The performance qualification articles have numerousparagraphs describing general applicable variables for allprocesses. QW-350 and QB-350 list additional essentialvariables which are applicable for specific processes.The QW-350 variables do not apply to welding opera-tors. QW-360 lists the additional essential variables forwelding operators.

Generally, a welder or welding operator may bequalified by mechanical bending tests, radiography ofa test plate, or radiography of the initial productionweld. Brazers or brazing operators may not be qualifiedby radiography.

WELDING AND BRAZING DATAThe welding and brazing data articles include the

variables grouped into categories such as joints, basematerials and filler materials, positions,preheat /postweld heat treatment, gas, electrical charac-teristics, and technique. They are referenced from otherarticles as they apply to each process.

These articles are frequently misused by selectingvariables that do not apply to a particular process.Variables (QW-402 to QW-410 and QB-402 to QB-410) only apply as referenced for the applicable process

xxvi

in Article II or Article III for welding and Article XIIor Article XIII for brazing. The user of Section IXshould not try to apply any variable which is notreferenced for that process in QW-250, QW-350, QW-360, QB-250, or QB-350.

These articles also include assignments of P-Numbersand F-Numbers to particular base materials and fillermaterials. Article IV also includes A-Number tablesfor reference by the manufacturer.

Beginning with the 1994 Addenda, the welding P-Numbers, brazing P-Numbers, and nonmandatory S-Numbers were consolidated into one table identifiedas QW/QB-422. Both the QB-422 table (brazing P-Numbers) and Appendix C table (S-Numbers) weredeleted. The new QW/QB-422 table was divided intoferrous and nonferrous sections. Metals were listed innumerical order by material specification number toaid users in locating the appropriate grouping number.An abbreviated listing of metals grouped by P-Numbers,Appendix D, has been included for users still wishingto locate groupings of metals by welding P-Number.

The QW-451 and QB-451 tables for procedure quali-fication thickness requirements and the QW-452 andQB-452 tables for performance thickness qualificationsare given and may only be used as referenced by otherparagraphs. Generally, the appropriate essential variablesreference these tables.

Revisions to the 1980 Edition of Section IX intro-duced new definitions for position and added a filletweld orientation sketch to complement the groove-weldorientation sketch. The new revision to position indicatesthat a welder qualifies in the 1G, 2G, 3G, etc., positionand is then qualified to weld, in production, in the F,V, H, or O positions as appropriate. QW-461.9 is arevised table that summarizes these new qualifications.

The data articles also give sketches of coupon orienta-tions, removal of test specimens, and test jig dimensions.These are referenced by Articles I and XI.

QW-470 describes etching processes and reagents.At the end of Articles IV and XIV is a list of

general definitions applicable to Section IX, weldingand brazing, respectively. These may differ slightlyfrom other welding documents.

Nonmandatory Forms for welding and brazing proce-dure and performance qualifications appear in AppendixB. These forms are provided for the aid of those whodo not wish to design their own forms. Any form(s)that address all applicable requirements of Section IXmay be used.
