Done both, welded material on and rotated out. Oil and ViceGrips, mostly works.
Had good luck with reverse drill bits. Start as small as possible and keep upsizing. Usually the friction heat and constant reverse torque turn out the broken stud. |

BTW, a 4" pipe wrench works much better than vice grips as it continually tightens its grip with additional force. IOW, it won't slip like vice grips. |
