A1. Introduction

A2. Classification System

A2.4.4 The request must be sent to the Secretary of the Committee on Filler Metals and Related Materials at AWS Headquarters. A2.4.6 The Secretary shall include in the agenda for each Committee on Filler Metals and Supplementary Materials meeting a copy of the log of all requests pending and those completed during the preceding year.

A3. Acceptance

If more than 12 months have passed, the Secretary will notify the requester of the status of the request, with copies to the Chairs of the Committee and Subcommittee. Requests that are still outstanding after 18 months will be considered not answered in time and the Secretary will report them to the Chair of the Committee on Filler Metals and Related Materials for action.

A4. Certification

Any other publication of inquiries that have been conducted will be at the option of the American Welding Society as deemed appropriate. Certification" shall not be construed to mean that testing of any kind was necessarily performed on samples of the specific material shipped.

A5. Ventilation During Welding

The only testing requirement implicit in this certificate is that the manufacturer has actually performed the tests required by the specification on material representative of the material being shipped and that the material meets the requirements of the specification. The representative material in this case is any production batch of this classification using the same formulation.

A6. Welding Considerations

There can be considerable variation in weld metal resistance unless special attention is paid to the welding procedure and to the preparation and testing of specimens. A6.11.2 Electrodes are manufactured to be within acceptable humidity limits, consistent with the type of coating and the strength of the weld metal.

A7. Description and Intended Use of Electrodes

A7.3.3 E6012 [E4312] electrodes are all-position electrodes and are usually suitable for welding in the vertical up or down progression welding position. A7.10.2 E7024 [E4924] electrodes are suitable for making fillet welds in a flat or horizontal position.

A8. Special Tests

An AWS Subcommittee A5A task group evaluated this test and concluded that it can successfully distinguish between moisture-resistant and non-moisture-resistant electrodes. The task force concluded that the variability was due to both differences in exposure conditions and inherent variability in the application of the moisture test procedure.

A9. Discontinued Classifications

The accuracy of the test is such that, with moisture-resistant electrodes from a single batch, participating laboratories were able to observe exposed cover moisture values ranging from, for example, 0.15% or less to 0.35% or more. Therefore, it is currently not realistic to set a limit for moisture coverage of exposed moisture-resistant electrodes below 0.4%.
