3、Allied MaterialsUnder the Direction of theAWS Technical Activities CommitteeApproved by theAWS Board of DirectorsAbstractThis specification prescribes the requirements for classification of carbon and low-alloy steel flux cored electrodes forflux cored arc welding and metal cored electrodes for gas
4、metal arc welding. The requirements include chemical compo-sition and mechanical properties of the weld metal and certain usability characteristics. Optional, supplemental designa-tors are also included for diffusible hydrogen and to indicate conformance to special mechanical property requirementswh
5、en the weld metal is deposited using low heat input, fast cooling rate and high heat input, slow cooling rate proce-dures. Additional requirements are included or referenced for standard sizes, marking, manufacturing, and packaging. Aguide is appended to the specification as a source of information
6、concerning the classification system employed and theintended use of carbon and low-alloy steel flux cored and metal cored electrodes.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 independ

34、ch, with the application of the specified toler-ances, provides for interchangeability of products in both the U.S. Customary and SI Units.This new AWS A5.36/A5.36M specification utilizes two classification systems. The first of these is a “fixed classifica-tion system” which has been carried over t
35、o this specification from AWS A5.20/A5.20M or AWS A5.18/A5.18M, asapplicable, for the classification of those carbon steel flux cored electrodes or carbon steel metal cored electrodes which,with the specific mechanical properties specified for them in AWS A5.20/A5.20M or AWS A5.18/A5.18M, have gaine
36、dwide acceptance for single and multiple pass applications. The classification designations and requirements for thesespecific electrodes are unchanged from those previously specified in AWS A5.20/A5.20M or AWS A5.18/A5.18M. Alisting of these electrodes with their requirements is given in Table 1.Th
37、is AWS A5.36/A5.36M specification also utilizes a new, “open classification system” which is introduced in this doc-ument for the classification of carbon and low-alloy steel flux cored and metal cored electrodes. The open classificationsystem uses designators to indicate electrode type (Usability D
38、esignator), welding position capability, tensile strength,impact strength, shielding gas (with more options and new designations), condition of heat treatment, if any, and welddeposit composition. The change to an open classification system is being made to allow for the classification of fluxcored
39、and metal cored electrodes with classification options which (1) better define the performance capabilities of theadvanced electrode designs that have been developed, and (2) reflect the application requirements of todays market-place. In addition, the provision has been made in this document for th
40、e classification of metal cored electrodes (usabil-ity Designator T15) and two new electrode types (Usability Designators T16 and T17) for the classification of metalcored and flux cored electrodes designed for use with AC power sources with or without modified waveforms. TheEXXT-2X classification h
41、as been discontinued. Electrodes previously classified as EXXT-2X can now be classifiedunder the new open classification system without requiring a unique “2” Usability Designator. The EXXT-13 electrodeclassification has been discontinued due to lack of commercial significance. For a complete listin
42、g of the affected exist-ing electrode classifications and the corresponding equivalent classifications using the open classification system underAWS A5.36/A5.36M, refer to A9 in Annex A.Two additional changes to note are (1) the fillet weld test, previously required under AWS A5.20/A5.20M and AWSA5.
43、29/A5.29M (and also detailed in ISO 15792-3) is not a required test under AWS A5.36/A5.36M, and (2) the preheatviiiAWS A5.36/A5.36M:2012and interpass temperature requirements for the “D” optional, supplemental designator have been modified for betteragreement with AWS D1.8/D1.8M, Structural Welding
