If it snaps off again then drill through the centre of the stud with ever growing sizes of drills. Use cutting fluid.if you're slightly off centre you will come to the edge of stud then it will loosen up enough to turn what is left. Don't be tempted to drill further than that.
Above all don't break the drill bit in it. Start with about 3mm and work up from there. Once the first hole is done the rest will be easier. Just go steady. The drilling bit should take about half hour to an hour to do it nice and steady. The welding bit would take me ten mins most
And all I would add to that is the drilling around the stud with a small drill to powder the corrosion.
