No, V grooved to increase the weld contact area for strength. This is a common practice in welding steel. Notching it will not necessarily allow more penetration. Not as good of penetration as a V groove will allow. Grooving it allows significantly more surface area for the weld material to attach too. Do a little research on Tig welding if you think i am wrong.
