Abstract
For on-line monitoring and controlling the quality of resistance spot welding, we design a high speed data acquisition and spot welding signal processing system. System hardware, which are made up of PLC 1800 high speed data acquisition card current sensor voltage sensor signal adjust circuit and IPC, is mainly responsible for A/D conversion and data acquisition; software system are mostly made up of data acquisition and memory module wavelet filtering of digit signal module U-I image and energy analyze module in electric signal of spot welding, which realize the data acquisition and processing base on welding current electrode voltage welding cycle. The experimental result showed that U-I image shape of different material are markedly dissimilar in spot welding, according to U-I image we can check if welding current and electrode voltage are normal in welding process or not, and through U-I image we can read the input energy of every U-I curve half-cycle and judge spot welding quality. Therefore, we can take U-I image monitoring method in spot welding quality monitoring of different material.
