Description
technical field [0001] The invention belongs to the technical field of welding equipment, in particular to a spot welding equipment for a generator excitation device. Background technique [0002] Spot welding is a high-speed and economical connection method, which is mainly suitable for the welding of thin plates, stamping structures and wires with a thickness of less than 4 mm. At present, the welding of the excitation device of the generator is mostly completed by spot welding with a general-purpose welding machine, which has the defect of low welding efficiency. Moreover, workers are required to operate it, and the labor intensity of the workers is high. When the workers are tired, there are certain safety hazards; the quality of the workers has a great influence on the welding quality, and the welding quality is unstable. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a spot welding equipment for gene...
