Arc-welding monitoring system and method

Abstract

The invention discloses an arc welding monitoring system and method. The system includes: an electrical signal acquisition module for acquiring electrical signals in the arc welding process; an AD conversion module for acquiring the electrical signals acquired by the electrical signal acquisition module, and The electrical signal performs analog-to-digital conversion; the FPGA control module is used to send the corresponding analog-to-digital conversion control signal, and performs probability density statistics, effective value calculation and welding time statistics according to the data output by the AD conversion module; the first storage module is used for Store the data calculated or counted by the FPGA control module; the ARM processing module is used to call the data in the first storage module, and perform curve drawing and corresponding digital information on the called data through the preset statistical resolution and waveform setting parameters Statistics; a display module, used for displaying the curve and digital information output by the ARM processing module. The equipment cost can be effectively reduced, the volume of the equipment can be reduced, and the process monitoring can be extended to the actual welding production environment.

Description

technical field [0001] The invention relates to the technical field of arc welding monitoring, in particular to an arc welding monitoring system and method. Background technique [0002] Modern welding pays more and more attention to the high-efficiency evaluation of welding quality. On-line monitoring of the welding process is an important method to improve the evaluation efficiency, and it is also one of the important development directions in the current welding field. [0003] Through the welding process data, the quality evaluation of the welding process can be carried out to effectively ensure the quality of the weld and improve the yield rate of the entire production process. However, there is a lack of monitoring equipment for the welding process in the actual welding site. Traditional PC-based welding monitoring equipment is mostly used for laboratory research, which has the disadvantages of bulky, high cost, and isolation, and has not been popularized in the actual...
