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 (SI), 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.
