Abstract

The invention discloses a quick-response tungsten-rhenium thermocouple welding device. The device mainly comprises a transformer, a rheostat, a support seat, a clamp, an electric conductor, an electrode plate and the like, wherein the rheostat is used for adjusting the resistance of a discharge circuit of a thermocouple, and realizing the consistency of discharge currents of two thermo wires of the thermocouple; and the electric conductor is a gallium alloy, so that the welding strength of the thermocouple and the purity of thermo nodes are guaranteed. The device has the following remarkable advantages: the device is simple in composition and convenient to operate; and the welded tungsten-rhenium thermocouple is high in forming rate, small in thermo node size, short in response time, and capable of meeting the quality control requirement of quick response of thermal effect measurement for an explosion field.

Description

technical field [0001] The invention belongs to the technical field of thermocouple welding, and relates to a tungsten-rhenium thermocouple welding device, in particular to a fast-response tungsten-rhenium thermocouple welding device. Background technique [0002] With the development of high-efficiency damage technology, a number of technical achievements have been made in the research of new high-energy explosive technology, and thermobaric explosive products with various formulas have been developed, some of which have been applied to warhead models and equipped with troops. Compared with traditional high explosives, the post-combustion stage of thermobaric explosives releases a large amount of heat, which produces a sharp high temperature effect and suffocation effect in a limited space, killing the living forces hidden in closed shelters such as buildings or caves. Therefore, in the process of thermobaric explosive formula research and formula inspection / verification, a...
