The invention relates to an intelligent infrared temperature welding machine, and belongs to the field of industrial automation. The intelligent infrared temperature welding machine comprises a powersupply, an electric wire, a welding machine body, an electrode holder, an infrared temperature sensor, a temperature transmitter, a PI controller, a current transmitter and a current proportion controller, wherein the power supply is connected with the welding machine body through the electric wire, and the welding machine body is connected with the electrode holder; the welding machine body, thecurrent transmitter, the current proportion controller and the PI controller are connected in sequence to form a subloop for monitoring welding current; and the infrared temperature sensor is fixed onthe electrode holder, and the infrared temperature sensor, the temperature transmitter and the PI controller are sequentially connected to form a main loop for monitoring the molten pool temperatureof a welding point. According to the intelligent infrared temperature welding machine, a cascade control system is adopted for adjustment, the influence of system disturbance can be overcome through the cascade control system, and therefore the stability of the system is improved, the welding material can be rapidly welded, and the welding quality is improved.

Description

technical field [0001] The invention relates to an intelligent infrared temperature welding machine, which belongs to the field of electromechanical integration products. Background technique [0002] Now my country's industry is in a stage of vigorous development, most of the industrial development will use welding devices, and our country's current welding devices are welded by adjusting the welding current of the welding machine. There is a proportional relationship between the arc temperature and the welding current. The larger the welding current, the higher the arc temperature, and the lower the welding current, the lower the arc temperature. The arc temperature directly affects the quality of the molten pool on the weldment. bad. The arc temperature of the welding point has a very significant impact on the welding quality. When the welding current is large and the arc temperature of the welding point is too high, the weld will be fully burned, some metal components w...
