Positions of both end edges of a weld bead in a bead width direction are measured over the entire circumference of a liner in a circumferential direction of the liner. Based on information on the position of the end edge, bead profile information being information on a shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction is created. Based on this bead profile information, machining information of the liner per rotation of the liner being position information of a cutting tool in the bead width direction per phase in the circumferential direction of the liner is created so that a moving locus of the cutting tool relative to the liner along the circumferential direction of the liner approximates the shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction.

Disclosed is a ferrule type wheel deburring device, which includes a machine frame, cylinders, motors, clamp units, a brush, guide posts, guide sleeves, etc. According to the ferrule type wheel deburring device, when in use, the size of a lower brush can be automatically adjusted according to the diameter of a wheel, and burrs of all places of a front surface of the wheel can be effectively removed; and meanwhile, the ferrule type wheel deburring device has the characteristics of advanced technology, high degree of automation, high universality and safe and stable performance.

A flash-removal tool comprises a tool body, extending along a longitudinal tool axis, and a tooth, projecting from the tool body in a first direction. The flash-removal tool further comprises an engagement surface, perpendicular to the longitudinal tool axis and located a preselected distance away from the tooth along the longitudinal tool axis. The tooth comprises a shearing surface, facing in the first direction and located an offset distance away from the longitudinal tool axis in a second direction. The first direction and the second direction are orthogonal to each other and define a plane, perpendicular to the longitudinal tool axis.

A seam ripping assembly for use in preparing a coiled tubing operation in a production well, such as, for example, in the oil and gas industry. More particularly, the present invention pertains to a method and apparatus for seam dressing that can be used to efficiently remove a weld seam along an inner diameter on a section of coiled tubing, thereby allowing a coil connector to then be able to attach to an end of said section of coiled tubing.

A method of removing flash from a gauge portion of a monolithic precursor test coupon using a flash-removal tool is provided. The flash-removal tool comprises a tool body, extending along a longitudinal tool axis, a tooth, and an engagement surface, spaced apart from the tooth along the longitudinal tool axis. The tooth projects from the tool body in a first direction and comprises a shearing surface, facing in the first direction and located an offset distance away from the longitudinal tool axis in a second direction. The method comprises steps of coupling the engagement surface of the flash-removal tool against a first precursor-coupon end of the monolithic precursor test coupon, orienting the longitudinal tool axis parallel to a longitudinal symmetry axis of the monolithic precursor test coupon, wherein the shearing surface registers longitudinally with the flash, and shearing, using the shearing surface, the flash from the gauge portion.

A cold-weld burr removal system is disclosed according to various embodiments. The cold-weld burr removal system can include a clamping block having a clamping passage that extends along an alignment axis, and a removal block having a guide passage alignment axis centered about the alignment axis. The removal block can define a burr receiving chamber. The system also can include a cutting head insert having a cutting portion and a cutting passage. The cutting head insert can removably attach to the removal block and the cutting portion can protrude into the burr receiving chamber. The system can include a linear actuator that connects the clamping block to the removal block. The linear actuator can move the removal block in a direction along the alignment axis to increase a separation distance between the clamping block and the removal block when a linear actuation initiator initiates movement of the linear actuator.

The flash removal unit presented herein is suitable for a friction stir welding (FSW) head and includes a blade and an annular body. The blade removes flash created by a FSW tool during FSW operations. The an annular body defines a flash capture area around the blade and is configured to at least temporarily retain the flash removed by the blade within the flash capture area. The flash removal unit may also define a flow path along which the flash can be suctioned away from the flash removal unit.
