Specification for Nickel and Nickel-Alloy Bare Welding Electrodes and Rods Supersedes ANSI/AWS A5.14/A5.14M-97
Prepared by AWS A5 Committee on Filler Metals and Allied Materials Under the Direction of AWS Technical Activities Committee Approved by AWS Board of Directors
Abstract The chemical compositions of nearly fifty nickel and nickel-alloy welding electrodes and rods are specified, including thirteen compositions not previously classified. Major topics include general requirements, testing, packaging and application guidelines. This specification makes use of both U.S. Customary U nits and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.

Specification for Nickel and Nickel-Alloy Bare Welding Electrodes and Rods
1. Scope
amendments to, or revisions of, any of these publications do not apply. However, parties to agreement based on this AWS standard are encouraged to investigate the possibility of applying the most recent editions of the documents shown below. For undated references, the latest edition of the standard referred to applies.
1.1 1.1 This specification prescribes requirements for the classification of bare nickel and nickel-alloy welding electrodes, strip electrodes, and welding rods. It includes those compositions where the nickel content exceeds that of any other element.
2.2 The 2.2 The following AWS standards 1 are referenced in the mandatory sections of this document: (1) (1) AWS AWS A1.1 A1.1,, Metric Practice Guide Gui de for f or the t he Welding Industry (2) AWS AWS A5.0 A5.01, 1, Filler Metal Procurement Guidelines
1.2 Safety 1.2 Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safety and health information can be found in the nonmandatory annex, Sections A5 and A10. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes , and applicable federal and state regulations.
2.3 2.3 The following ANSI standard 2 is referenced in the mandatory sections of this document: (1) ANSI ANSI Z49. Z49.1, 1, Safety in Welding, Cutting, and Allied Processes
1.3 This 1.3 This specification 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 in any way when referring to material properties. The specification with the designation A5.14 uses U.S. Customary Units. The specification A5.14M uses SI Units. The latter latter are shown shown within brackets brackets [ ] or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for sizing of filler metal or packaging or both under A5.14 or A5.14M specifications.
2.4 2.4 The following ASTM standards 3 are referenced in the mandatory sections of this document: (1) (1) ASTM ASTM E 29, 29, Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications (2) (2) ASTM ASTM E 76, 76, Standard Methods for Chemical Analysis of Nickel-Copper Alloys (3) ASTM DS-56H/SAE HS-1086, Metals & Alloys in the Unified Numbering System 1.

3. Classification 3.1 3.1 The welding filler metals covered by the A5.14/A5.14M specification are classified using a system that is independent of U.S. Customary Units and the International System of Units (SI). Classification is according to the chemical composition of the filler metal, as specified in Table 1.
7. Summary of Tests Chemical analysis of the filler metal, or the stock from which it was made, is the only test required for classification of a product under this specification.
3.2 A 3.2 A filler metal classified under one classification shall not be classified under any other classification in this specification.
8. Retest
3.3 3.3 The filler metals classified under this specification are intended for use with the plasma arc, gas metal arc, gas tungsten arc, and submerged arc welding processes, but this is not to prohibit their use with any other process for which they are found suitable.
If the results of any test fail to meet the requirement of that test, that test shall be repeated twice. The results of both retests shall meet the requirement. Material for retest may be taken from the original test sample or from a new sample. Retest need be only for those specific elements that failed to meet the test requirement.

If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this specification for that classification.

In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing test specimen(s) or in conducting the test, the test shall be considered invalid, without regard to whether the test was actually completed, or whether test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling of the number of test specimens does not apply.
