The present disclosure relates to a method for producing a final metal part for a nacelle of a turbojet. The method includes brazing at least two parts, one being an inner part having an inner surface and the other being an outer part having an outer surface. The method further includes a step of heating the outer surface of the outer part using an external heating means, and a step of heating the inner surface of the inner part using an internal heating means.

A soldering iron system with automatic variable temperature control comprising a hand piece or robot arm including a soldering cartridge having a soldering tip, a coil that generates a magnetic field, and a temperature sensor for sensing a temperature of the soldering tip; a variable power supply for delivering variable power to the coil to heat the soldering tip; a processor including associated circuits for accepting a set temperature input and the sensed temperature of the soldering tip, and providing a control signal to control the variable power supply to deliver a suitable power to the coil to keep the temperature of the soldering tip at a substantially constant level of the set temperature input.

A solder reflow apparatus may include a vapor generating chamber configured to accommodate a heat transfer fluid, a heater configured to heat the heat transfer fluid, a vertical transfer portion, and at least one substrate stage. The vertical transfer portion may include a vertical conveyer supported by a driving pulley and a driven pulley so as to be rotatable in an endless track, the vertical conveyer having a conveying route of a descending path and an ascending path in the vapor generating chamber, and at least one substrate stage fixedly fastened to one side of the vertical conveyor by a fastening portion so as to be raised and lowered in the vapor generating chamber by rotation of the vertical conveyor. The at least one substrate stage may be configured to support a substrate on which an electronic component may be mounted via a solder.

The present disclosure comprises methods, apparatus, components, and techniques for soldering. A soldering tool includes opposing jaw pieces adapted to grip and/or compress work pieces while applying heat. The work pieces can be heated to a temperature at or above the melting point of a solder material, whereupon the solder may be melted and applied at the work pieces. The soldering tool may be removed from the work pieces, thereby allowing the solder to solidify and form a soldered joint. Soldering tools may be powered by portable, rechargeable, and/or detachable battery packs that are readily accessible and commonly used for a wide variety of hand-operated power tools.
