摘要： A welding system for welding small precious metal firing tips to spark plug electrodes, such as ground and/or center electrodes. According to one embodiment, the welding system includes a firing tip storage assembly and a firing tip welding assembly, where the firing tip storage assembly uses pressurized gas introduced at the bottom of a part container to float or lift the firing tips so that the firing tip welding assembly can more easily acquire them with a vacuum-driven nozzle that also doubles as a welding electrode. The firing tip welding assembly is mounted to a robotic apparatus that can index or move the firing tip welding assembly between the firing tip storage assembly, a welding station and/or any other suitable positions.

摘要： A nut feeding apparatus for feeding a weld nut to an upper electrode of a resistance welding machine, whose size and production cost are reduced, is disclosed. The apparatus comprises a piston rod, a tension rod, a tube, a link mechanism and a nut chuck. When the piston rod is in a most retracting state, an upper surface of the nut chuck becomes substantially flush with a lower portion of an opening of the tube. While the tension rod is at a stop in a most advancing state and when the piston rod further advances, the link mechanism rotates around a rotation axis at a tip of the tension rod, and thereby, the weld nut held by the nut chuck moves to a feeding position of the weld nut in the upper electrode.

摘要： A process for projection welding a steel weld nut to an ultra high strength steel component using a direct current projection welding machine is provided. The process includes placing a steel weld nut at a predetermined location on the steel component such that the at least one projection of the weld nut is in direct contact therewith. The DC projection welding machine passes a current through the at least one projection that is in direct contact with the steel component a predetermined amount of weld time, which in turn creates a resistance weld joint between the weld nut and the steel component as is known to those skilled in the art. The predetermined amount of weld time is less than 1 Hz (16.67 sec) and the weld joint between the weld nut and the steel component has a twist off strength greater than 30.0 newton meters (Nm).

摘要： A method for repairing a degraded bolt hole in a casing flange by reaming and removing at least some corrosion on an inside and around the hole to form a reamed hole, mounting the flange to float relative to upper and lower electrodes of a welding machine, radially and axially clamping an area of the flange surrounding the reamed hole, placing upper and lower filler slugs in the reamed hole, placing the electrodes against upper and lower filler slugs and applying a welding current through the electrodes while applying pressure to the filler slugs with the electrodes and resistively heating and melting the filler slugs to form a weldment, and pulsing the welding current on and off. Pulsing may be performed with progressively increasing amounts of current. In situ tempering under the pressure of the electrodes may be performed on a substantially liquid pool formed by the welding current.

摘要： An electrical conduction mechanism is provided to prevent dust or from adhering to the inside of an electrical-con duction portion main body, so that electrical conduction efficiency cannot be reduced. The electrical conduction mechanism comprises an electrical-conduction portion main body in the center of which a first through-hole to be inserted through by a shaft is formed and in which a second through-hole communicating with the first through-hole is formed in a direction perpendicular to a direction in which the first through-hole is formed. The electrical-conduction element is disposed in the second through-hole. The electrical-conduction element is configured to include an electrical-conduction chip abutting on the shaft, and a coil spring biasing the electrical-conduction chip toward the shaft, so that current is supplied to the shaft through the electrical-conduction chip to conduct electricity to the bit.

摘要： A rail repair method and insert therefor enables repair of rails and rail-like structures. A rail defect is initially identified and removed as contained within a volumetric material portion so as to form a contoured void while maintaining continuity of the rail opposite the void. A pre-formed insert is then placed into the void thereby effecting a rail-to-insert interface. Current is driven through the interface as force directs the insert against the rail. Resistance heat and pressure weld the insert to the rail. The flash welding aspects remove oxides and other impurities from the interface, and the forge welding aspects create a robust solid state weld. Excess material, whether flash, rail, or insert-based, is removed during the finishing processes to provide a virtually seamless rail repair. The solid state weld repair insert and underlying methodology enabled thereby may be used to repair any number of targeted metallic rail-like structures.

摘要： A weld gun system for detecting the orientation of a weld nut relative to the metallic component to which it is to be welded prior to welding is disclosed. The system includes a lower electrode having a weld location pin, an upper electrode having a central circular recess formed therein, a fluid supply fluidly connected to the central circular recess of the upper electrode, and a pressure switch also fluidly connected to the central circular recess of the upper electrode. Once the weld nut is captured between the electrodes the fluid flows from the fluid supply into the central circular recess of the upper electrode. If the weld nut is in proper orientation the fluid continues to flow to the pressure switch and the weld occurs. If the weld nut is not in proper orientation the fluid does not flow to the pressure switch but is instead vented from the central circular recess and the weld does not occur.
