  • Publication number: 20210219390
    Abstract: An induction heating apparatus is provided. The induction heating apparatus includes a heating coil, an inverter, a current sensor configured to measure a driving current supplied from the inverter to the heating coil, and a controller configured to provide a drive signal to the inverter to allow the driving current to follow a target current based on a user input. The controller reduces a driving duty of the drive signal based on the driving current exceeding a predetermined reference current, and the controller provides a drive signal to the inverter to allow the driving current to follow a current less than the target current, based on the driving current being less than or equal to the predetermined reference current after reducing the driving duty of the drive signal.

  • Patent number: 9878489
    Abstract: Friction-weld assemblies and methods of spin-welding are provided, where the components being joined are polymeric components. Designs provided for the polymeric components enable the use of relatively low speeds and pressures to achieve superior friction weld joints between the components. Further, large surface area polymeric components can be successfully friction welded with such designs. In certain variations, at least one polymeric component has a weld surface with a plurality of surface features that are concave (e.g., grooves) or convex. In other variations, the first component in the weld region has a distinct non-complementary shape from the second component, thus creating a progressive advancing weld line that avoids high temperatures that might incur damage to the polymeric component and weld joint. Such component designs additionally provide for improved flash management at the weld joint.
