Abstract:
A method of forming a solder joint between a coaxial cable and a coaxial connector includes the steps of: positioning a solder element between an end of an outer conductor of the coaxial cable and a connector body of the connector, wherein the solder element is positioned within a vacuum chamber; melting the solder element to form a solder joint between the outer conductor and the connector body, the solder joint including a lower surface formed by contact with a mounting structure; and applying suction to the melting solder element to reduce the formation of bubbles within the solder joint.

Abstract:
There are many situations requiring temperature regulation in heating elements which the prior art feedback control systems are not capable of handling adequately. In order to provide a temperature regulation in a narrow range around the Curie temperature, the electrical heating element of the present invention is consisted of a core 7(25) or a substrate 35 of a non-magnetic material having high thermal and electrical conductivity, clad with a surface layer 9(27, 37) of a ferromagnetic material of relatively low electrical conductivity. When the heating element is energized by an electrical source 3(41) of high frequency alternating current, the skin effect initially confines current flow principally to the surface layer of ferromagnetic material. As temperature rises into the region of the Curie temperature of the ferromagnetic material, however, the decline in magnetic permeability of the ferromagnetic material causes a significant lessening of the skin effect, permitting migration of current into the high conductivity non-magnetic core or the substrate, thereby simultaneously enlarging the cross-sectional area of the current flow path and expanding it into the highly conductive material; the resistance of the heating element becomes less due to both causes. By selecting the proper frequency for energization, by regulating the source to produce constant current, and by selecting dimensions and material parameters for the heating element, temperature regulation in a narrow range around the Curie temperature of the ferromagnetic material can be produced, despite considerable fluctuations in thermal load.

The housing includes a first opening configured to permit placement of the end portion of the first tubular within the housing during brazing, a second opening configured to permit placement of the end portion of the second tubular within the housing during brazing, and a purge opening configured to provide inert gas to the housing. A method may include providing the apparatus described, providing the first tubular, and providing the second tubular. The method also includes placing the end portion of the first tubular in the first opening of the housing and placing the end portion of the second tubular in the second opening of the housing.

Abstract:
An inductive heating (34) is added to a metal working process, such as a welding process, by an induction heating head (36). The induction heating head (36) 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 (36). The heating is in addition to heat from a welding arc (50), 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.
