First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.

A cutting system for removing an excess material along a length of a channel constructed using an additive manufacturing process is disclosed. In various embodiments, the cutting system includes a cutting component having an abrasive surface configured to remove the excess material along a down-facing surface of the channel and a smooth surface configured for sliding contact with an up-facing surface of the channel; and a motive component configured to urge the cutting component through the channel.

A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.

A stabilizer includes bend sections. With respect to positions in a circumferential direction of a radial cross section of each of the bend sections, a center of an inside of a bend is defined as 0, and a center of an outside of the bend is defined as 180. The bend sections each include a bend interior section located at 0, a bend exterior section located at 180, a first side section located at 90, and a second side section located at 270. The bend interior section has compressive residual stress from a surface to a first depth. The bend exterior section has compressive residual stress to a second depth. The first side section has compressive residual stress to a third depth. The second side section has compressive residual stress to a fourth depth.

A system for blast-cleaning a barge deck, sides, and fittings providing for safety and avoidance of damage to the barge and to persons, where a barge is blast-cleaned with moving blaster units suspended from and traveling along an overhead track beam. In one embodiment, the moving blaster units are each controlled by a person in a moving operator capsule moving in tandem with a moving blaster unit. In another embodiment, the moving blaster units are robotically controlled from a robotic controller which has access to a three-dimensional plan of the barge, communicating with the robotic blaster units via RF antennae, and receiving real-time data from sensors located on each blaster head. Optionally, the system for blast-cleaning a barge can provide blaster-head cameras for real-time remote monitoring of operations and for recording of the operations allowing review of any issue, such as damage, that might arise.
