Counter Bore or Counter Sink Methods
When an arc stud is welded, a fillet forms around its base with the fillet dimensions being closely controlled by the design of the ferrule used. Since the diameter of the fillet is generally larger than the diameter of the stud, some consideration is required in the design of mating parts. Counter bore and counter sink methods are commonly used. Dimensions will vary with studs and ferrules. Additional methods of accommodating fillet includes oversize clearance holes, use of a gasket material around the fillet or use of a dog type construction.

IF AN OVERSIZE FILLET DOES NOT MEET THE APPLICATION:
Welded studs designed with a reduced weld base are available so that the weld fillet does not exceed the maximum diameter of fastener. This design is not recommended if full fastener strength is important.
