Proper amount of welds?

My floor pan has this amount of welds welding it to the rocker panel. Is this a sufficient amount of welds or should I do more. This is a pic I just found of someone else`s car on here. Hope they don`t mind for me borrowing it.

Yes that would be plenty I generally space them 2 1/2 - 3 inches and drill them 5/16".
