AWS A5.39/A5.39M PDF
This specification prescribes requirements for the classification of flux-electrode combinations using submerged arc or electroslag welding. Flux-electrode joining classifications include requirements for soundness, mechanical properties and weld metal composition. Flux-electrode cladding classifications include requirements for soundness and weld metal composition. Electrode classification is per AWS A5.9/A5.9M for solid and stranded stainless steel electrodes, A5.14/A5.14M for solid and stranded nickel-alloy electrodes, A5.22/A5.22M for cored stainless steel electrodes and A5.34/A5.34M for cored nickel-alloy electrodes.
This specification makes use of both US Customary Units and the International System of Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to weld metal properties. The specification with the designation A5.39 uses US Customary Units. The specification with the designation A5.39M uses SI units. The latter are shown within brackets [ ] or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for the sizing of electrodes or packaging or both under specification A5.39 or A5.39M.
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 the nonmandatory annex, Clauses B5 and B10.

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.
