Abstract

The invention relates to a manual intermediate frequency welding control cabinet. A sample curve is built through analyzing qualified welding spots; in the welding process, welding current and resistance are detected and fed back per each millisecond, and welding current and time are automatically adjusted through analysis of a welding controller (1) and comparison with the sample curve; adjustment is performed according to the principle of conservation of energy, when welding time extension is opened, the adjusting function of the welding controller (1) can ensure that energy of the actually welded welding spot is more than or equal to that of a sample welding spot; if splash compensation exists, after the splash is found, loss of metal liquid is compensated by prolonging welding time; if disturbance compensation exists, procedure parameters depart from the sample, that causes disturbance, the disturbance can be found and compensated by variation of current and time, and the variation value depends on the type of disturbance.

Description

technical field [0001] The invention relates to a manual intermediate frequency welding control cabinet. Background technique [0002] With the development of science and technology and the improvement of manufacturing technology, welding technology has been used more and more in mechanical structures. Compared with other processing techniques, welding technology has outstanding advantages, such as relatively simple equipment structure, good on-site performance, and adaptability to various working conditions. The prominence of these advantages also puts forward higher requirements for welding equipment. As an important part of the welding machine, the resistance welding machine plays an important role in fields such as automobiles, aerospace, and home appliances due to its unique technological characteristics. [0003] At present, the development of the entire automobile industry is moving towards saving resources and reducing environmental pollution. Reducing the weight ...
