Tube beading is a metal forming process that forms a bead on the end of a tube.
Internal roll forming is generally slower than ram forming but it holds tight tolerances.
Serrated clamp jaws are used to hold the tube while radial pressure is applied by an internal roller to form the bead.
Ram forming is quicker and usually preferred when speed of production is a concern.
The automotive industry usually uses this process over internal roll-forming.
