Specification for Nickel-Alloy Electrodes for Flux Cored Arc Welding

2nd Edition

Supersedes AWS A5.34/A5.34M:2007

Prepared by the American Welding Society (AWS) A5 Committee on Filler Metals and Allied Materials

Under the Direction of the AWS Technical Activities Committee

Approved by the AWS Board of Directors

Abstract

The composition, soundness, and properties of weld metal from ten grades of flux cored electrodes are specified. Standard electrode sizes together with their package forms and package sizes are detailed.

This specification makes use of both U. S. customary units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.

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 governmen- tal 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 amend- ments or errata, or supplemented by publication of addenda. Information on the latest editions of AWS standards includ- ing 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 Doral Blvd., Suite 130, Doral, 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 required 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 com- ments. 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 pro- vided in the Rules of Operation of the Technical Activities Committee. A copy of these Rules can be obtained from the American Welding Society, 8669 Doral Blvd., Suite 130, Doral, FL 33166.

Foreword

This foreword is not part of AWS A5.34/A5.34M: 2013, Specification for

Nickel-Alloy Electrodes for Flux Cored Arc Welding, but is included for informational purposes only.

Flux cored arc welding (FCAW) has been a major welding process for the fabrication of carbon, low-alloy, and stainless steel for more than 40 years. Initially, application of the process was limited, to some extent, by: a) the size of the elec- trode that could be manufactured and b) compositions of weld metal that could be developed using mild steel strip. Manufacturing improvements now permit the manufacture of a much wider range of electrode diameters. Likewise, these improvements permit the use of strip compositions such as stainless steel, aluminum, cobalt, and nickel alloys.

This second edition of nickel-alloy flux cored electrodes specification represents the state-of-the-art. The AWS Subcommittee on Nickel and Nickel-Alloy Filler Metal recognizes that the recent rapid growth and development in nickel-alloy welding will continue. Revision of this specification before the normal five-year period may be necessary to keep abreast of developments.

This document makes use of both U.S. Customary Units and the International System of Units (SI). The measurements are not exact equivalents; therefore each system must be used independently of the other, without combining values in any way. In selecting rational metric units AWS A1.1, Metric Practice Guide for the Welding Industry, and ISO 544 Consumables—Technical delivery conditions for welding filler materials—Type of product, dimensions, tolerances and markings are used where suitable. Tables and figures make use of both U. S. Customary and SI units, which, with the application of the specified tolerances, provides for interchangeability of products in both the U.S. Customary and SI units.

Substantive changes in this revision include adding new filler metal classification ENiMo13Tx-y, and updating Clause 6 (Rounding-Off Procedure). These are shown in Italic font.

Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary, A5 Committee on Filler Metals and Allied Materials, American Welding Society, 8669 Doral Blvd., Suite 130, Doral, FL 33166.
