Are these swedged or not? help

So maybe or maybe not swedged? I supposed I can start grinding off the weld and see what happens. Also any insight as to the 083 on the studs? Does that mean Dorman 610-083 that has a knurl of .563? Scarebird suggests the 9in hub takes a different stud than the 10in hub. and that I need longer studs. So I bought 610-114 which has a .582 knurl. Are those gonna be too big? Should I search for new longer studs that have the same .563 knurl?
