When an arc stud is welded, a fillet forms around its base with the fillet dimonsions being closely controlled by the design of the ferrule used Since the diameter of the fillet is generally large than the diameter of the stud. some consideration is required in the design of mating arts.MIDWEST FASTENERS recommends a counter bore and counter sink method for this application. Dimensions will vary with studs and ferrules. Additional methods of accommodating fillet include over-sized clearance holes,use of a gasket material around the fillet or use of a dog type onstruction.

SEVERAL OPTIONAL METHODS OF FILLET ACCOMMODATION |
| |
 |
(A) OVERSIZE CLEARANCE
HOLE |
(B) GASKET MATERIAL |
(C) DOG CLAMP |
|
| |
| IF AN OVERSIZE FILLET DOES NOT MEET THE APPLICATIONS: |
A MIDWEST FASTENERS weld stud designed with a reduced weld base is 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. |
