This specification prescribes the requirements for classification of surfacing electrodes for shielded metal arc welding. Classification is based upon the chemical composition of the deposited weld metal except for tungsten carbide electrodes where classification is based on the mesh range, quantity, and composition of the tungsten carbide granules. A guide is appended to the specification as a source of information as to the characteristics and applications of the classified electrodes.

This foreword is not part of AWS A5.13/A5.13M:2010, Specification for Surfacing Electrodes for Shielded Metal Arc Welding, but is included for informational purposes only.
The first AWS specification for surfacing filler metals was published in 1956 as a joint ASTM/AWS specification. It was the first of what would later become a two-set series, A5.13 and A5.21.
The composite electrodes and rods classifications were removed from the 1970 revision of A5.13 and placed into a new specification, A5.21. A5.13–70 specification contained requirements for both covered and bare electrodes or rods employing solid core only. This distinction was maintained for the 1980 revision of A5.13.
The revisions of both A5.13:2000 and A5.21:2001 incorporated a totally different scope. The method of manufacture of the core of the electrode or rod was no longer a factor in determining placement of a classification. Instead, the covered electrode products were classified under AWS A5.13:2000 and the bare electrode products under AWS A5.21:2001.
This document is the first of the A5.13 specifications which 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, ANSI/AWS A1.1, Metric Practice Guide for the Welding Industry, and ISO 544 Welding consumables – Technical delivery conditions for welding filler materials – Type of product, dimensions, tolerances and marking, are used where suitable. Tables and figures make use of both the U.S. Customary and SI Units, which, with the application of the specified tolerances, provides for interchange- ability of products in both the U.S. Customary and SI Units.
Rounding-off Procedure has been revised in this edition. Detailed general safety information in Clause A9 has been replaced by Safety and Health Fact Sheets. Such substantive changes are shown in Italic font in this specification.
The historical evolution of the specification is:
ASTM A 399-56T Tentative Specification for Surfacing Welding Rods and Electrodes
AWS A5.13-56T
AWS A5.13-70 Specification for Surfacing Welding Rods and Electrodes
ANSI W3.13-73
ANSI/AWS A5.13-80 Specification for Solid Surfacing Welding Rods and Electrodes
AWS A5.13:2000 Specification for Surfacing Electrodes for Shielded Metal Arc Welding
Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary, AWS A5 Committee on Filler Metals and Allied Materials, American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.

Scope
This specification prescribes requirements for the classification of surfacing electrodes for shielded metal arc welding. Solid bare electrodes and rods for surfacing are classified in AWS A5.21:2001, Specification for Bare Electrodes and Rods for Surfacing (see Clause A8 in Annex A).
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 Clauses A5 and A9 in Annex A. 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.
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 A5.13 uses the U.S. Customary Units. The specification A5.13M uses the SI Units. The latter are shown within 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 A5.13 or A5.13M specifications.
