Portable thermocouple spot welding machine suitable for multiple materials

Abstract

The invention discloses a portable thermocouple spot welding machine suitable for multiple materials and can inhibit generation of relatively large electric sparks under parameters of relatively high capacitance and relatively low voltage to form solder balls. A thermocouple is welded with various material surfaces with a high success rate through wire feeding, so that the problem that welding of the thermocouple on metal materials such as copper and aluminum by a conventional spot welding machine is not firm and even the thermocouple cannot be spot-welded is solved. Through adoption of a pen container type welding electrode and a function of automatically and quickly feeding wires, the phenomenon that the welding environment is severe is solved and the condition that the welding effect is poor as a result of an imprecise operation technology is avoided. The product designed by the invention is small in size, portable and easy to operate. Compared with conventional tin soldering and the thermocouple with a groove formed on the surface of a metal material, the temperature measuring precision is greatly improved, and a lot of energy loss as the temperature of an engineering material cannot be precisely measured or the temperature of the engineering material cannot be measured is reduced.

Description

technical field [0001] The invention belongs to the technical field of thermocouple spot welding, and in particular relates to a portable thermocouple spot welding machine suitable for multiple materials. Background technique [0002] At present, the development of thermocouple spot welding technology at home and abroad only stays in the use of high-voltage discharge to weld the surface of stainless steel and iron, and there is no testing standard for the strength of thermocouple welding on the surface of the material. Although foreign countries have done more research on some welding processes in the welding process, and more in-depth research on thermocouple tip solder balls, the functions of the overall welding machine are the same as those in China, with single functions and traditional welding processes. The body is too large to bring inconvenience to operation and portability. At present, all welding techniques are cumbersome to operate, and only skilled operators can...
