Beading

Beading can serve to provide a seat or stop on the outside of the tubular component. If the bead diameter is only slightly larger than the original tube diameter, a friction fit can be developed between the bead and the mating part.  Since the bead is essentially free form, the shape is not easily controlled.

Subsequent to beading, thermal treatment may be required to relieve stresses and improve mechanical integrity.
