AWS A5.34:2018 pdf download.Specification for Nickel-Alloy Flux Cored and Metal Cored Welding Electrodes
1. Scope
1.1 This specification prescribes requirements for the classification of nickel- alloy flux cored electrodes for flux cored arc welding and the classification of nickel-alloy metal cored electrodes which may be used with various welding proc-esses. See AWS A3.0M/A3.0 for the definitions of both types of electrodes. It includes alloy compositions in which the nickel content exceeds that of any other element, but excludes nickel-base alloy compositions intended for the joining of cast irons.
1.2 This specification makes use of both U.S. Customary Units and the International System of Units (SD), according to the guidelines in AWS A1.1. The measurements are not exact equivalents; therefore, each system must be used independ-ently of the other without combining in any way when referring to material properties. SI units 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 the A5.34 or A5.34M specification.
1.3 Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is provided, but such issues are not fully addressed herein. Some safety and health information can be found in Annex Clauses A5 and AIO.
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing the safety program.
2. Normative References
2.1 The following standards contain provisions which, through reference in this text, constitute provisions of this AWS standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However,parties to agreement based on this AWS standard are encouraged to investigate the possibility of applying the most recent editions of the documents shown below. For undated references, the latest edition of the standard referred to applies.
3.1 The electrodes covered by the A5.34/A5.34M specifications are classified using a system that is independent ofU.S.Customary Units and the International System of Units (SI).Classification of electrodes for flux cored welding is accord-ing to the chemical composition of the undiluted weld metal, the shielding gas employed during welding, and the welding position, as specified in Tables 1 and 2. Classification of metal cored electrodes is according to the chemical composition of the electrodes, based on the chemical compositions specified in AWS A5.14/A5.14M.AWS A5.34 pdf download.
