<p>Removal of the internal weld bead from welded tube while in longitudinal movement. Comprises a plug positioned axially in the tubing with a diameter portion in contact with the bead and an opposite internal surface area of the tube, outer drive for plug movement by sequential application of compressive force to the tube, return drive to the plug axially to its original position upon release of the compressive force whereby the internal weld bead is removed by axial reciprocation of the plug.</p> |
