Description

technical field [0001] The invention relates to the technical field of digitization technology of welding power supply, in particular to a digital human-computer interaction system of high-power twin-wire pulse MIG welding power supply. Background technique [0002] It is known in the industry that high-efficiency welding process innovation and equipment innovation are one of the important supports for welding technology innovation. High-efficiency welding is mainly manifested in two aspects: one is the substantial increase in welding speed when welding thin plates; Substantial improvement in application efficiency. To achieve high-efficiency welding of large and thick plates, the key is to further increase the welding current, such as the use of high-power twin-wire high-efficiency welding technology and equipment. High-power twin-wire automatic welding technology is a main way of high-efficiency welding. Compared with conventional twin-wire automatic welding technology be...

AI Technical Summary

Problems solved by technology

[0006] (1) The setting is mainly simulated through the potentiometer, and accurate digital setting cannot be realized

[0007] (2) Multi-parameters of high-power twin-wire pulsed MIG welding power sources cannot be stored and recalled

[0008] (3) The anti-interference ability is not good enough to ensure reliable work in the environment of strong arc light and strong electromagnetic field of high-power welding

[0009] For example, the patent number is: 200810042932.7, and the name is: the invention patent of "full digital numerical control inverter welding machine". Although the invention patent adopts ARM digital control technology, the liquid crystal display module of the man-machine interface only displays welding conditions and historical records. and other information, so there are the above defects

[0010] Another example is the "Human-machine interface design of submerged arc welding automatic control system based on ARM and Linux" in the existing technical literature (Zhang Wenming, Ju Hongtao, Liu Hongjun. Metal casting and forging technology, 2011.10) is a submerged arc welding based on ARM and Linux The man-machine interface of the welding control system. Although the man-machine interface can realize the functions of monitoring, recording and saving welding parameters, it is only for submerged arc welding, not high-power twin-wire pulse MIG welding.
