3、ller MetalsUnder the Direction ofAWS Technical Activities CommitteeApproved byAWS Board of DirectorsAbstractClassification requirements are specified for fluxes and solid and composite metal cored electrodes for electroslagwelding. The requirements for electrodes include chemical composition of the

4、electrode for solid electrodes and of weldmetal for metal cored electrodes. Requirements for fluxes include the mechanical properties and soundness of weldmetal taken from a groove weld made with a particular electrode using a prescribed welding procedure. Standard elec-trode sizes, marking, and pac

5、kaging requirements are included.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalent, each system must be used independently of the other.Key Words Filler metal specifications, low-alloy steel electrodes, carbon steel el

7、odes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS standards are either incorporat

8、ed in, or made part of, docu-ments that are included in federal or state laws and regulations, or the regulations of other governmental bodies, theirprovisions carry the full legal authority of the statute. In such cases, any changes in those AWS standards must be ap-proved by the governmental body

9、having statutory jurisdiction before they can become a part of those laws and regula-tions. In all cases, these standards carry the full legal authority of the contract or other document that invokes the AWSstandards. Where this contractual relationship exists, changes in or deviations from requirem

10、ents of an AWS standardmust be by agreement between the contracting parties.International Standard Book Number: 0-87171-539-2American Welding Society, 550 N.W.

The measurements

37、are not exact equivalents; therefore, each system must be used independently of theother, without combining in any way. In selecting rational metric units, the ANSI/AWS A1.1, Metric Practice Guide forthe Welding Industry, and ISO 864, Solid Wires for Gas Shielded Metal Arc Welding of Mild Steel, are

38、 used as guides. Ta-bles and figures make use of both U.S. Customary and SI Units, which with the application of the specified tolerancesprovide for interchangeability of products in both U.S. Customary and SI Units.The current document is the second revision of this specification, as shown below:Do
