If you have a deposited root and then you remelt prior to filling the joint - no problem as noted by metengr.
However, if by root bead "remelt" you mean getting inside the pipe and "blending" LOF or other defects by remelting the root you will require a repair procedure for most exotic materials as you are adding an additional heat cycle to the weld.
