Abstract
An external weld bead is removed and processed from a welded pipe traveling in a downstream direction. The weld bead is separated from the pipe, allowed to flow in a downstream direction, and is guided downstream and cut into chips at a location downstream of where the weld bead is separated from the pipe. Also disclosed is weld bead cutting tool including a cutting edge at an upstream end of the tool, a guide feature disposed downstream of the cutting edge and extending toward a downstream end of the tool, wherein the guide feature widens from the upstream end toward the downstream end.
Claims1
A method of removing and processing an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- separating the weld bead from the pipe while the pipe travels in the downstream direction;
- allowing the separated weld bead to flow in the downstream direction;
- guiding the separated weld bead in the downstream direction;
- and
- cutting the separated weld bead into chips at a location in the downstream direction from where the weld bead is separated from the pipe.
