FILARC flux- andmetal- coredwelding wiresKey to AWS classifications,continuedContents page 4AWS A5.20-95. Specification for carbon steel electrodes for flux cored arc welding.It covers all cored wire types, except metal-cored.(example: E71T-1MJ H4) E X X T - X M J - HZPrevious pageNext pageSymbol for electrodeMinimum tensile strength (in psi x 10 000)Welding positions of the electrode0 = flat and horizontal position only1 = all positionsIndicates flux-cored electrodeNumber from 1 through 14 or the letter “G” with orwithout an “S” following, referring to the usability ofthe electrode. The “G” indicates that the external shielding,polarity, and impact properties are not specified; the “S”that the electrode is suitable for a weld consisting ofa single pass, only.An “M” indicates that the the electrode is classified using75-80% Ar/balance CO 2 shielding gas. When the “M”does not appear, it signifies that either the shielding gasused for classification is CO 2 or that the product is self-shielded.Optional supplemental designatorsDesignates that the electrode meets the requirements of thediffusible hydrogen test (an optional supplemental test of theweld metal with an average value not exceeding “Z” ml ofH 2 /100g of deposited metal where “Z” is 4, 8, or 16).Designates that the electrode meets 27J at –40°C. Absence ofthe “J” indicates normal impact requirements.20
