| a.
All weld metal tension tests in the as-welded condition, see AWS A5.1 for
more det |
| b.
For the E60 series, each increase of one percentage point in elongation over
the minimum, the tensile strength or yield strength, or both, |
| may
decrease 1000 psi to a minimum of 60 ksi (420 MPa) for the tensile strength
and 48 ksi (330 MPa) for the yield strength for all |
| classifications
of the E60 electrodes except E6012, E6013, and E6022. For the E6012 and
E6013 classificaftions, the tensile strength and |
| yield
strength may decrease to a minimum of 65 ksi (450 MPa) for the tensile
strength and 53 ksi (365 MPa) for the yield strength. E6022 |
| electrodes
are for single-pass welding, and the yield strength/elongation measurement
is not required. |
| c.
For the E70 series, each increase of one percentage point in elongation over
the minimum, the tensile strength or yield strength, or both, |
| may
decrease 1000 psi to a minimum of 70 ksi (480 MPa) for the tensile strength
and 58 ksi (400 (MPa) for the yield strength. |
| d.
Upon agreement between the supplier and purchaser, electrodes classified as
E7016 or E7018 may be supplied to a minimum Charpy |
| V-notch
impact requirement of 20 ft-lb at -50 F (27 J at -46 C). Such electrodes
shall be identified as E7016-1 or E7018-1, as appropriate. |
| e.
Upon agreement between supplier and purchaser, electrodes classified as
E7024 may be supplier to a minimum Charpy V-notch impact |
| requirement
of 20 ft-lb at 0 F (27 J at -18 C) and a minimum elongation of 22 %. Such
electrodes shall be identified as E7024-1 |
