fw = shear strength of the weld metal is a function of the electrode used in the SMAW process. - The tensile strength of the weld electrode can be 60, 70, 80, 90, 100, 110, or 120 ksi. - The corresponding electrodes are specified using the nomenclature E60XX, E70XX, E80XX, and so on. This is the standard terminology for weld electrodes.
