SPECIFICATION FOR CARBON STEEL ELECTRODES FOR SHIELDED METAL ARC WELDING
SFA-5.1
(Identical with AWS Specification A5.1-91)

1.

Scope

4.

Certification

This specification prescribes requirements for the classification of carbon steel electrodes for shielded metal arc welding.

By affixing the AWS specification and classification designations to the packagings, or the classification tothe product, the manufacturer certifies that the product meets the requirements of this specification.3

PART A — GENERAL REQUIREMENTS 2. Classification
5. Units of Measure and Rounding-Off Procedure

2.1 The welding electrodes covered by this specification are classified according to the following: (1) Type of current (see Table 1) (2) Type of covering (see Table 1) (3) Welding position (see Table1) (4) Mechanical properties of the weld metal in the as-welded or aged condition (see Tables 2 and 3) 2.2 Materials classified under one classification shall not be classified under any other classification of this specification, except that E7018M may also be classified as E7018 provided the electrode meets all of the requirements of both classifications.

5.1 U.S. Customary Units are the standardunits of measure in this specification. The SI Units are given as equivalent values to the U.S. Customary Units. The standard sizes and dimensions in the two systems are not identical, and for this reason, conversion from a standard size or dimension in one system will not always coincide with a standard size or dimension in the other. Suitable conversions, encompassing standard sizes of both, can bemade, however, if appropriate tolerances are applied in each case. 5.2 For the purpose of determining conformance with this specification, an observed or calculated value shall be rounded to the “nearest unit” of the last right-hand place of figures used in expressing the limiting value in accordance with the round-off method of ASTM Practice E29 for Using Significant Digits in Test Data toDetermine Conformance with Specifications.4

3.

Acceptance

Acceptance1 of the welding electrodes shall be in accordance with the provisions of the ANSI/AWS A5.01, Filler Metal Procurement Guidelines.2
