Abstract

The invention provides a thermocouple welding device. The thermocouple welding device includes a welding component and a power supply line, wherein the welding component includes a device base; a first carbon rod and a second carbon rod are arranged on the device base; the tip end of the first carbon rod and the tip end of the second carbon rod are opposite to each other in the axial direction ina spaced mode; the first carbon rod and the second carbon rod are connected in the power supply line in series; and when the power supply line is in power supply state, an electric arc can be formed in a gap between the tip end of the first carbon rod and the tip end of the second carbon rod. According to a thermocouple welding device of the invention, through the two opposite carbon rods arrangedin a spaced mode and the power supply line electrically connected to the two carbon rods, the electric arc is formed between the two carbon rods for arc welding of a thermocouple, professional welding equipment in the prior art is not required, the manufacturing cost is reduced, the principle is simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of thermocouple welding, and in particular relates to a thermocouple welding device. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The manufacture of thermocouples requires the heating and welding of two special-shaped wires through professional welding equipment to form a circuit for temperature testing. For the laboratory, the cost of using professional welding equipment is high and the operation is complicated, so the present invention is proposed based on the aforementioned deficiencies of the prior art. Contents of the invention [0003] Therefore, the technical problem to be solved by th...
