Statement on the Use of American Welding Society Standards

All standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of the American National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, or made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standards must be approved by the governmental body having statutory jurisdiction before they can become a part of those laws and regulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWS standard must be by agreement between the contracting parties.

AWS American National Standards are developed through a consensus standards development process that brings together volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers the process and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.

AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance on this standard. AWS also makes no guarantee or warranty as to the accuracy or completeness of any information published herein.

In issuing and making this standard available, AWS is neither undertaking to render professional or other services for or on behalf of any person or entity, nor is AWS undertaking to perform any duty owed by any person or entity to someone else. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek the advice of a competent professional in determining the exercise of reasonable care in any given circumstances. It is assumed that the use of this standard and its provisions is entrusted to appropriately qualified and competent personnel.

This standard may be superseded by new editions. This standard may also be corrected through publication of amendments or errata, or supplemented by publication of addenda. Information on the latest editions of AWS standards including amendments, errata, and addenda is posted on the AWS web page (www.aws.org). Users should ensure that they have the latest edition, amendments, errata, and addenda.

Publication of this standard does not authorize infringement of any patent or trade name. Users of this standard accept any and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of any patent or product trade name resulting from the use of this standard.

AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.

Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request, in writing, to the appropriate technical committee. Such requests should be addressed to the American Welding Society, Attention: Managing Director, Technical Services Division, 8669 NW 36th St # 130, Miami, FL 33166 (see Annex B). With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered. These opinions are offered solely as a convenience to users of this standard, and they do not constitute professional advice. Such opinions represent only the personal opinions of the particular individuals giving them. These individuals do not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations of AWS. In addition, oral opinions are informal and should not be used as a substitute for an official interpretation.

This standard is subject to revision at any time by the AWS A5 Committee on Filler Metals and Allied Materials. It must be reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions, or deletions) and any pertinent data that may be of use in improving this standard are requested and should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee on Filler Metals and Allied Materials and the author of the comments will be informed of the Committee’s response to the comments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials to express their comments verbally. Procedures for appeal of an adverse decision concerning all such comments are provided in the Rules of Operation of the Technical Activities Committee. A copy of these Rules can be obtained from the American Welding Society, 8669 NW 36th St # 130, Miami, FL 33166.

Foreword

This foreword is not part of AWS A5.15:1990 (R2016). Specification for Welding Electrodes and Rods for Cast Iron, but is included tor informational purposes only.

The first specification for electrodes and rods for welding cast iron was published more than thirty years ago as a joint ASTM/AWS document. The first revision that was exclusively an AWS specification was published in 1969 and revised in 1982.

Significant changes made in this reaffirmed edition are correction of “1/16 (.016) in 0.4 mm” to “1/16 (.062) in 1.6 mm” in the table of Figure 3. updating the addresses of various organizations, and updating the list of “AWS Filler Metal Related Documents.”

Evolution of the document is as shown below:

ASTM A398-56T AWS A5.15-56T

Tentative Specification for Welding Rods and Covered Electrodes for Welding Cast Iron

AWS A5.15-65T ASTM A398-65T

Tentative Specification for Welding Rods and Covered Electrodes for Cast Iron

AWS A5.15-69 ANSI W3.15-1973

Specification for Welding Rods and Covered Electrodes for Welding Cast Iron

ANSI/A WS A5. 15-82 Specification for Welding Rods and Covered Electrodes for Cast Iron

Specification for Welding Electrodes and Rods for Cast Iron

1. Scope

   This specification prescribes requirements for the classification of the following:

   1. Rods for oxyfuel gas welding

   2. Electrodes for gas metal arc welding

   3. Electrodes for flux cored arc welding

   4. Electrodes for shielded metal arc welding

      These filler metals are suitable for welding gray cast iron, malleable cast iron, nodular cast iron, compacted graphite cast iron, and certain alloy cast irons.1

      
      

2. Classification

   1. The electrodes and rods covered by this specification are classified according to chemical composition, as specified in Tables 1A, 1B, and 1C.

   2. Electrodes and rods classified under one classification shall not be classified under any other classification in this specification.

   3. The electrodes and rods classified under this specification are intended for oxyfuel gas welding, shielded metal arc welding, gas metal arc welding, or flux cored arc welding, as applicable, but that is not to prohibit their use with any other process for which they are found suitable.

   
   

3. Acceptance

   Accepiance2 of the welding electrodes shall be in accordance with the provisions of ANSI/AWS A5.01. Filler Metal Procurement Guidelines.3

   
   

4. Certification

By affixing the AWS specification and classification designations to the packaging, or the classification to the product, the manufacturer certifies that the product meets the requirements of this specification.4

1 Copper-base filler metals frequently used in the braze welding of east iron are no longer included in this specification. For more information pertaining to these materials see A7.6 in the Annex A.

2 See section A3 (in the Annex A) for further information concerning acceptance, testing of the material shipped, and ANSI/AWS A5.01. Filler Metal Procurement Guidelines.

3 AWS standards are published by the American Welding Society. 8669 NW 36th ST # 130. Miami. FL 33166.

4 See section A4 (in the Annex A) for further information concerning certification and the testing called for to meet this requirement.
