Abstract

A thermocouple vacuum fusion welding system is capable of being used for fusion welding of thermocouple wires with various types in a vacuum environment, removing air by vacuumizing to eliminate a thermocouple wire oxidizing reaction which is possibly caused when fusion welding on a butt joint end of the thermocouple wires is conducted and improve pyroelectric effect performance of a thermocouple. The thermocouple vacuum fusion welding system is characterized by comprising a vacuum chamber. Thermocouple wire fixtures are arranged in the vacuum chamber. A fusion welding carbon rod is arranged in a corresponding position where each thermocouple wire fixture clamps the butt joint end of the thermocouple wire. The fusion welding carbon rod is connected with a feed movement device. The thermocouple wire fixture is connected with one pole of a fusion welding power supply, and the fusion welding carbon rod is connected with the other pole of the fusion welding power supply.

Description

technical field [0001] The invention relates to a thermocouple wire welding technology, in particular to a thermocouple vacuum fusion welding system. Background technique [0002] Thermocouple welding is usually carried out in an atmospheric environment or a gas environment with oxygen components, but at the moment when the butt ends of thermocouple wires are welded, due to high temperature, the thermocouple wires are likely to cause oxidation reactions, thereby affecting the performance of thermocouples . Contents of the invention [0003] Aiming at the defects or deficiencies in the prior art, the present invention provides a thermocouple vacuum welding system, which can be used for welding various types of thermocouple wires in a vacuum environment. The thermocouple wire oxidation reaction may be caused when the thermocouple wire butt end is welded, thereby improving the thermoelectric effect performance of the thermocouple. [0004] Technical scheme of the present in...
