摘要： An induction welding system employs an induction welding apparatus with an induction welding power supply and a chiller in the same enclosure. An induction welding coil is powered by the induction welding power supply. A variable force press can press together work pieces and an actuator can move the induction welding coil lengthwise along a weld joint. The weld controller repeatably conducts induction welds by controlling the induction welding power supply to power the induction welding coil and controlling the induction welding tooling to at least one of press together work pieces to be welded and move the induction welding coil lengthwise along a weld joint between work pieces to be welded.

摘要： A method for forming a component includes providing a first layer of a mixture of first and second powders. The method includes determining the frequency of an alternating magnetic field to induce eddy currents sufficient to bulk heat only one of the first and second powders. The alternating magnetic field is applied at the determined frequency to a portion of the first layer of the mixture using a flux concentrator. Exposure to the magnetic field changes the phase of at least a portion of the first powder to liquid. The liquid portion couples to at least some of the second powder and subsequently solidifies to provide a composite component.

摘要： In certain embodiments, inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head may be adapted specifically for this purpose, and may include one or more coils to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.

摘要： A system used to additively manufacture an object layer-by-layer using direct energy deposition (DED) includes a base where the object is formed, a depositor configured to deposit material layer-by-layer on the base or a previously deposited layer of the object, an energy source configured to selectively direct an energized beam at the material to fuse a new layer of the material to a previously formed layer, and a heating element in contact with at least a portion of the base and configured to supply heat to the base.

摘要： A magnetic clamping heat sink assembly is disclosed including a magnetic assembly with a carrier body including a magnet. A spring resiliently biases the carrier body. A base assembly includes a base plate. In a first operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a first position away from a ferromagnetic element, and the spring holds the carrier body at a medial position spaced apart from the base plate. In a second operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a second position adjacent to the ferromagnetic element, and the carrier body is driven downward against a force of the spring to a lower position and into contact with the base plate by magnetic attraction between the at least one magnet and the ferromagnetic element.

摘要： Systems and methods are provided for controlling welding. One embodiment is a method for controlling welding of a composite part. The method includes locating a linear fiber optic sensor along a composite part comprising a matrix of thermoplastic reinforced by fibers, measuring temperatures along the weld line via the linear fiber optic sensor, performing induction welding at the composite part along the weld line, determining a continuum of weld temperatures along the weld line, and controlling the induction welding based on the continuum of weld temperatures.

摘要： Systems and methods are provided for controlling welding. One embodiment is a method for controlling welding. The method includes initiating induction welding by operating an induction coil along a weld interface of a first composite part comprising a matrix of thermoplastic reinforced by fibers, in order to join the first composite part to a second composite part, determining a measured magnetic field strength at a location distinct from the induction coil, and determining a welding temperature at the weld interface of the first composite part based on the measured magnetic field strength.
