The welding should be only on the lobe and not on the base circle. Altering the base circle will change the valve geometry which would require custom parts (i.e. rocker arms and/or push rods) to get back into specs. If you do weld on the base circle (for a repair) it will need to be return to the original base circle radius.
I also added some info here:
