Are these swedged or not? help

Update., So I ground down those 3 weld spots, and the hub dropped right out, not swedged to the drum. However the studs were still swedged to the hub, so that was fun.
I took it to a shop and they got them out, and pressed in new ones. Now it seems that the new studs have a shoulder that is not allowing the new disc to sit flush to the hub. Not sure what to do, unless maybe I need to enlarge the holes on the disc? They are 1/2, but the shoulder on the studs is more like 9/16? help?? These were the new studs that was suggested I needed because they need to be long Napa 641-1560 (Dorman 610-114) help?
