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.
Claims27
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a tool holder carrying a planing tool, which separates the weld bead from the pipe;
- a chopper located downstream of the planing tool to cut the separated weld bead into chips;
- and
- a body supporting the planing tool and the chopper and including a passage disposed between the planing tool and the chopper to guide the separated weld bead downstream through the body from the planing tool to the chopper.
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a first cutting device to separate the weld bead from the pipe;
- a second cutting device located downstream of the first cutting device to cut the separated weld bead into chips;
- and
- a guide disposed between the first and second cutting devices to guide the separated weld bead downstream from the first cutting device to the second cutting device.
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;
- allowing the separated weld bead to flow downstream;
- guiding the separated weld bead downstream;
- and
- cutting the separated weld bead into chips at a location downstream of where the weld bead is separated from the pipe.
A weld bead cutting tool, comprising:
- a cutting edge at an upstream end of the tool;
- and
- 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.
