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, guided through a guide passage having an inlet and an outlet, and cut into pieces at the guide passage outlet in a location above the pipe.
Claims20
An apparatus to remove and process an external weld bead from a welded pipe traveling in a downstream direction, comprising:
- a first cutter to separate the external weld bead from the welded pipe;
- a guide including a passage to guide the separated weld bead from the first cutter and having an inlet adjacent the first cutter and an outlet located above the inlet;
- a movable, second cutter located above the first cutter;
- and
- an actuator to reciprocate the second cutter to cut the separated weld bead into pieces between the second cutter and the stationary cutting tool.

An apparatus, comprising:
- a first support body;
- a second support body coupled to the first support body;
- deburring tooling carried by the second support body, and including:
- a first cutting device to separate an external weld bead from a welded pipe,
- a guide including a passage to guide the separated weld bead away from the first cutting device and having an inlet and an outlet,
