-
For structural members Select electrodes with a tensile strength equal to minimum tensile strength of 100
ksi.
-
For non-structural members Select electrodes with a tensile strength less than that of the base metal, but
within 70 to 80 ksi. Note: Typical non-structural members are fillet welds stressed in longitudinal shear,
welds carrying secondary stresses, or welds joining a lower strength metal to T-1 steel.
-
For dissimilar base metals Select electrodes with a tensile strength equivalent to that of the lowest strength
base metal used.

Note: XXX represents the electrode tensile strength in ksi as required for the welding
application.
b. Hydrogen Content . Use only low hydrogen content electrodes. T-1 steel is extremely susceptible to hydrogen-
induced cracking in weld metal and in heat affected zones. Precautions must be followed to reduce the presence
of hydrogen during welding including moisture contamination, a major source of hydrogen. The following general
procedures apply to low hydrogen electrode selection and use.
-
For shielded metal-arc welding use only low hydrogen electrodes which have electrode coating designations
(last two digits of the AWS classification) of 15, 16, 18, or 28 (for example, E8015, E9016, E11018).
