91 VERSION CONTAINED IN ASME PV CODE 2C AS SFA-5.3 Prescribes requirements for the classification of covered (flux coated) E1100, E3003, and E4043 aluminum alloy electrodes for shielded metal arc welding. Tests conducted for classification are chemical analysis of the core wire and tensile and bend tests on specimens from a groove weld test assembly fabricated with two sizes of electrode for each classification. Standard electrode sizes, electrode identification, and chemical composition limits are specified.
