You need to consider the welding process when using table 3.7.
Consider the single pass vertical fillet weld made with SMAW. A 1/2 inch fillet leg translates into a face dimension larger than 5/8 of an inch. There goe the 3X the rod diameter restriction for low hydrogen electrodes. There are no restrictions on the width of the second layer, third layer, etc., for SMAW.
It is doubtful that the restictions of depth versus width limitations imposed would be concern with SMAW. It would most likely be a concern with SAW.
Now, if notch toughness is an issue, I would be concerned with the width of the layers because of the implications on travel speed and heat input.
