For stress calculation of a 45° fillet weld with the leg length (L), the theoretical value of the throat thickness is 1/√2 or 0.707L, where L is the leg length of the fillet weld. In actual practice, the throat thickness of fillet welds has to be kept within the limit of 0.6L and 0.9L. See also Welding Skid.
The strength of the electrode should match the strength of the base metal. If yield stress (σy) of the base metal is ≤ 60 - 65 ksi, use E70XX electrode. If yield stress (σy) of the base metal is ≥ 60 - 65 ksi, use E80XX electrode. E70XX is the most popular electrode used for fillet welds made by the SMAW method.

EN 1993-1-8 4.7.1 (1) says that the resistance of a full penetration butt weld is equal to the resistance of the weaker of the 2 parts the butt weld connects. This applies as long as the tensile and yield strength of the weld are not less than the one from the parent metal/steel. This means that when the (full penetration) butt weld connects a
