AbstractAWS A5.16/A5 .16M:2007 is a revision of the titanium welding electrode document last revised in 2004. The compositionsspecified for each classification represent the state of the art. The specification contains testing procedures, standardsizes and forms, and identification and marking practices.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalent, each system must be used independently of the other.

Statement on the Use of American Welding Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericarWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, oimade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become a part olthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documemthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to.achieve consensus, ~~e AWS administers theprocess and establishes rules to.promote fairness in the development of consensus, it d6es net intdependently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments C('jfuai~itY itz~ dards.AWS disclaims liability for any injury to.persons or to.property, or o.therfi~j3s of any ~t re whatsoever, whetherspecial, indirect, consequential, or compensatory, directly or indirectl~~l]ng f r ' 0 1 : J th2ttblicatio.n, use of, or relianceo.n this standard.

ForewordThis foreword is not part of AWS AS.16/AS.l6M:2007, Specification for Titanium and Titanium-Alloy

Welding Electrodes and Rods, but is included for informational purposes only.

This document is the second of the AS.16 specifications which makes use of both U.S. Customary Units and the Inter-national System of Units (SI). The measurements are not exact equivalents; therefore, each system must be usedindependently of the other, without combining values in any way.

5. Certification

under test shall be considered as not meeting the require-ments of this specification for that classification.In the event that, during preparation or after completionof any test, it is clearly determined that specified OIproper procedures were not followed in preparing the testspecimens or in conducting the test, the test shall be con-sidered invalid, without regard to whether the test wasactually completed, or whether test results met, or failedto meet, the requirement. That test shall be repeated, fol-lowing proper prescribed procedures. In this case, therequirement for doubling the number of test specimensdoes not apply.

9. Chemical AnalysisBy affixing the AWS specification and classification

For the purpose of determining conformance with thisspecification, an observed or calculated value shall berounded to the "nearest unit" in the last right-hand placeof figures used in expressing the limiting value in accor-dance with the rounding -off method given in ASTM E 29.

7. Summary of TestsChemical analysis of the filler metal or the rodstock from which the filler metal is made is the onlytest required for classification of a product under thisspecification.

8. RetestIf the results of any test fail to meet the requirement, thattest shall be repeated twice. The results of both retestsshall meet the requirement. Material for retest may betaken from the original sample or from a new sample.Retest need be only for those specific elements thatfailed to meet the test requirement. If the results of one orboth retests fail to meet the requirement, the materials

10. Method of ManufactureThe welding electrodes and rods classified according tothis specification may be manufactured by any methodthat will produce material that meets the requirements ofthis specification.

11. Standard Sizes and Lengths11.1 Standard sizes and lengths for electrodes and rods inthe different package forms (straight lengths, coils withsupport, coils without support, and spools) are shown inTable 2.

12. Finish and Uniformity12.1 All electrodes and rods shall have a smooth finishthat is free from slivers, depressions, scratches, scale,seams, laps, and foreign matter that would adverselyaffect the welding characteristics, the operation of thewelding equipment, or the properties of the weld metal.12.2Each continuous length of filler metal shall be froma single heat or lot of material, and welds, when present,shall have been made so as not to interfere with the uni-form, uninterrupted feeding of the filler metal on automaticand semiautomatic equipment.

AnnexAGuide to AWS Specification for Titanium andTitanium-Alloy Welding Electrodes and RodsThis annex is not part of AWS A5.I6/5.I6M:2007, Specification for Titanium and Titanium-Alloy

Welding Electrodes and Rods, but is included for informational purposes only.

At. Introduction for corresponding base metals. See Table A.I for crossreference with the earlier designations.The purpose of this guide is to correlate the filler metalclassifications with their intended applications so thespecification can be used effectively. Appropriate basemetal specifications are referred to whenever that can bedone and when it would be helpful. Such references areintended only as examples rather than complete listingsof the materials for which each filler metal is suitable.

A2.3 Specific alloys are identified by a number similar tothe grade designation used inASTMI ASME8 specifications

determine whether the new classification or the modifi-cation of an existing classification is more appropriate,and whether either is necessary to satisfy the need.In particular, the request needs to include:(a) All classification requirements as given for exist-

ing classifications, such as, chemical composition ranges.(b) Information on Description and Intended Use,

which parallels that for existing classifications, for thatclause of Annex A.

A2.2 The chemical symbol "Ti" appears after "R" asa means of identifying the filler metals as unalloyedtitanium or a titanium-base alloy. The numeral provides ameans of identifying different variations in the composition.

The act of placing the AWS specification and classifica-tion designation on the packaging enclosing the productor the classification on the product itself, constitutes thesupplier's (manufacturer's) certification that the productmeets all of the requirements of the specification. Theonly testing requirement implicit in this certification isthat the manufacturer has actually conducted the testsrequired by the specification on material that is represen-tative of that being shipped and that the material met therequirements of the specification. Representative mate-rial, in this case, is any production run of that classifica-tion using the same formulation. Certification is not to beconstrued to mean that tests of any kind were necessarilyconducted on samples of the specific material shipped.Tests on such material mayor may not have been con-?:..===::":""O~=~=::....:;.:::....::==.:..=="'----;'Iuct~~. ~~asls for tfi~ cen_ifiC(jfl~ required by ~e

AS. Ventilation During WeldingAS.1 Five major factors govern the quantity of fumes towhich welders and welding operators are exposed duringwelding. They are:

(l) Dimensions of the space in which welding is done(with special regard to the height of the ceiling);(2) Number of welders and welding operators work-

ing in that space;(3) Rate of evolution of fumes, gases, or dust, accord-

ing to the materials and processes used;(4) The proximity of the welders or welding opera-

tors to the fumes as the fumes issue from the weldingzone, and to the gases and dusts in the space in whichthey are working; and

(S ) The ventilation provided to the space in which thewelding is done.AS.2 American National Standard Z49.I, Safety in Weld-ing, Cutting, and Allied Processes (published by theAmerican Welding Society), discusses the ventilation

AS.I Corrosion or Scaling Tests. Although welds madewith fillers in this specification are commonly used incorrosion and heat-resisting applications, tests for thoseproperties are not included in the specification. Whenrequired for a particular application, tests can be con-ducted on specimens taken from either a weld pad or awelded joint. Specimens from a joint are suitable forqualifying the welding procedure (for a specific applica-tion involving corrosion or oxidation resistance) but notfor qualifying the electrode. Tests on specimens from ajoint have the disadvantage of being a combined test ofthe properties of the weld metal, the heat-affected zone(HAZ), and the unaffected base metal. With them, it ismore difficult to obtain reproducible data (when a differ-ence exists in the properties of the metal in the variousparts of the specimen). Specimens taken from a jointhave the advantage of being able to duplicate the jointdesign and the welding sequence planned for fabrication.AS.I.I Specimens for testing the corrosion or oxida-

tion resistance of the weld metal alone are prepared byfollowing the procedure outlined in A8.1.2 of the specifi-cation. The pad size should be at least 3/4 in [19 mm] inheight, 2-112 in [65 mm] in width, and 1 + 5 /8 n(in) [25 +16 n{mm}] in length, where n represents the number ofspecimens required from the pad. Specimens measuring112x 2 x 114 in [13 x 50 x 6.4 mm] are machined fromthe top of the pad in a manner such that the 2 in [50 mm]dimension of the specimen is parallel with the 2-112 in[65 mm] dimension of the pad and the 11 2 in [13 mm]dimension is parallel with the length of the pad.AS.I.2 The heat treatment, surface finish, and mark-

ing of the specimens prior to testing should be in accor-dance with standard practices for tests of similar alloys inthe wrought or cast forms. The testing procedures shouldcorrespond to those of ASTM G 4, Standard Guide forConducting Corrosion Tests in Field Applications, orASTM G 31, Standard Practice for Laboratory Immer-sion Corrosion Testing of Metals, as the case may be.
