Brief description of embodiments of a junction between two metal wires of a dimension very reduced, and measurement devices which realized from this junction

摘要

P of a junction between two metal wires. / p & & p & there is obtained a stack of the two wires placed end to end and having a cross section of a contact. This stack is placed in a tube closed at its two stiffener. This tube is made of a material whose thermal expansion coefficient is very inferior to that of the two wires. Shims are interposed between the stiffener free of the two wires. The assembly is subjected to a temperature such that one obtains a welding of the stiffener in contact with the filaments under the effect of the difference of the elongations of the tube and the wires. / p & & p & application to the embodiment of the thermocouples or probes of the neutron flux of the outer diameter reduced. / p
