3、 Direction ofAWS Technical Activities CommitteeApproved byAWS Board of DirectorsAbstractClassification requirements are specified for solid and composite (flux cored and metal cored) electrodes for electro-gas welding. The requirements include chemical composition of the electrode for solid electrod
4、es and of weld metal forcomposite (cored) electrodes, in addition to the mechanical properties and soundness of weld metal taken from a grooveweld made with these electrodes using the prescribed welding procedure. Standard electrode sizes, marking, and packag-ing requirements are included.This speci
5、fication 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 electrodes, welding electrodes, flux cored el

7、tices, 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).

8、t 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 having statutory jurisdiction before t
9、hey 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 requirements of an AWS standardmust be by agre
