American Electrode Classification
American Electrode Classification
(OP)
I am looking Section J.2 of the AISC specification and trying to determine a weld capacity as per Table J2.5.
It seems fillet strength is based on FEXX (an electrode classification number in ksi).
Where would I find this information as the commentary came up blank.
Ideally I would be looking for something similar to an E42 Electrode to BS EN 499 (Min Yield Strength 420MPa, UTS 500-640MPa)

RE: American Electrode Classification
If you need to use an American electrode, they come in 10-ksi increments, but the E80 electrodes are just weathering versions of the E70s. E70 electrodes (485 MPa) are most typically used for building and bridge construction with 50-ksi (345 MPa) steel. E90 electrodes are used with Gr. 70 steel.

In a nut shell the basic AWS classification for SMAW filler metal is EXXXX, where: E stands for electrode, the next two digits nominal tensile strength in ksi, the penultimate digit is welding position, and final number is for coating/operating characteristics.
So, as an example, for an electrode classified as E7018, the tensile strength is 70 ksi (which is the FEXXX in Table J2.5), the number 1 means it can be used for welding in all positions, the number 8 means the coating is low hydrogen iron powder ...for use with AC or DCEP.
