摘要： A thermoplastic welding assembly includes a structural cage that supports a press and one or more hydraulic and pneumatic actuators. The press includes first and second plates that movable toward and away from each other to load and remove thermoplastic components to be held together for thermoplastic welding. Specifically, the first plate of the press includes non-conductive tooling inserts that are positioned to form a slot for a welding prove, and the second plates includes non-conductive tooling inserts that form cavities for plungers to move through. Plungers that are movable using the actuators are positioned in the cavities of the second plate, and compressible pressurizers are attached to the ends of the plungers. An operator uses electrical controls to move the plungers in the plunger cavities toward the thermoplastic components in the press to drive the pressurizers into the thermoplastic components and provide stabilizing pressure on the components during welding.

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： A thermoplastic welding assembly and method for joining a plurality of thermoplastic support components to a thermoplastic component is provided. The thermoplastic welding assembly includes a frame, a plurality of heat sinks, and a plurality of individually actuatable pressurizers. The frame includes a plurality of welding slots. Each heat sink of the plurality of heat sinks is positioned within one of the welding slots. Each pressurizer of the plurality of individually actuatable pressurizers includes an alignment actuator configured to move one thermoplastic support component into alignment with one welding slot, and a clamping actuator configured to move the one thermoplastic support component into contact with the thermoplastic component. In some implementations, the thermoplastic welding assembly further includes a plurality of actuators configured to move the alignment actuator and the clamping actuator.

摘要： A compression load distributor includes a support layer and a heat spreading layer. The support layer includes a flexible carrier configured to distribute a load from a compression load applying device. The heat spreading layer is coupled to and carried on the support layer, the heat spreading layer comprising a heat sink configured to transfer heat throughout the compression load distributor. The heat sink is thermally conductive and electrically non-conductive.

摘要： A method is provided for controlling an induction welding operation. The method includes sweeping electrical current through an induction welding coil at an initial position of the induction welding coil along a weld path of a material; monitoring a response of the material to the swept electrical current using at least one electromagnetic field (EMF) sensor; calibrating an electrical current value for the induction welding operation using the monitored response; and performing the induction welding operation along the weld path using the calibrated electrical current value.
