A device for performing a method for producing a lamination pack, wherein in the method laminations are cut from an electric strip or sheet; the laminations are placed on top of each other to form a lamination stack; the laminations are connected by material fusion to each other by: locally plasticizing a material of the laminations in an edge region of the laminations by generating friction heat by a tool; mixing the locally plasticized material, at least of the laminations neighboring each other, with the tool; and allowing the plasticized material to cool and fuse the laminations in the edge region to form the lamination pack. The device has a punch press and/or a receptacle for one or a plurality of lamination stacks. The device further has a welding tool that is rotatably driven about an axis of the welding tool and moveable transverse to the axis of rotation.

A method of creating a clad metal part is provided. The method includes explosion bonding a plate comprised of a base layer and an interlayer. The explosion bonded plate is then cut into bars which are roll bonded with a clad layer. Ultimately a part is fabricated from the roll bonded bar. The solution enables parts to have material combinations and resulting physical properties more optimal for an application than a single bonding process.

An electric wire arranging jig (40) has an electric wire arranging groove (16, 31, 41) configured to be inserted the electric wires. The electric wire arranging groove has a pair of arranging surfaces facing each other. The electric wire arranging groove is configured to have a cross-sectional shape, in a section perpendicular to a direction of the electric wires extending within the electric wire arranging groove, having a distance in a width direction of the electric wire arranging groove continuously narrowed from an insertion start portion for the electric wires toward a bottom portion of the electric wire arranging groove and the arranging surfaces each inclining from a vertical direction, at least in a part of a segment between the insertion start portion and the bottom portion.

The abutment portion touches with a shoulder surface of a joining tool for friction stir welding. The tip portion is freely movable in a first direction connecting a surface of the workpiece and the shoulder surface in a state of contacting the surface of the workpiece. The detector is configured to detect a position of the tip portion in the first direction. The output unit is configured to output a data of the position of the tip portion in the first direction detected by the detector. The controller is configured to calculate a position of the tip portion to the abutment portion from the data of the position output from the output unit, and to calculate a distance between the shoulder surface of the joining tool and the surface of the workpiece.

The present disclosure provides a system and method for measuring energy conversion efficiency of an inertia friction welding (IFW) process in a non-contact manner. The system includes an IFW machine, a Hall sensor, a data acquisition module, a processing module and a stabilized direct current (DC) power supply. The stabilized DC power supply provides electrical energy for the Hall sensor. The Hall sensor is provided beside a flywheel of the IFW machine, so that the flywheel is within a detection range of the Hall sensor. A magnet is provided on the flywheel. The data acquisition module acquires a Hall electric potential change caused by a relative movement between the magnet and the Hall sensor during the IFW process, and transmits the Hall electric potential change to the processing module to calculate the energy conversion efficiency of the IFW machine.

Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releasably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.
