  • Method to reduce weld flash
    Patent number: 4583386
    Abstract: The method and apparatus is disclosed to reduce the size of weld flash located at the junction of two workpieces each having a cylindrical contour and which have been butt-welded together. This method and apparatus employ roller members which positively feed the butt-welded workpieces through a slot opening smaller in width than the original diameter of the weld flash. In the preferred embodiment, a roller is spaced apart from the stationary block member to establish the slot opening while the workpieces are rotated while being fed through the opening in order to exert sufficient mechanical force with the sides of the slot opening to reduce the diameter of the weld flash by compaction during passage therethrough.
