| Abstract: | In view of the current penetration signal selection which constraints the penetration adaptive control in MIG welding, a set of software system based on graphic program language LabVIEW is designed for arc sound signal acquisition and analysis, with the functions of user login, parameter configuration and recording, signal acquisition and preview, data saving and overlanding, noise reduction as well as feature extration. The experimental result shows that the designed system can efficiently collect, process and analyze arc sound signal in real-time method, with advantages of easy implementation, fl＇iendly interface and steady performance. And it also provides and application foundation for penetration adaptive control via arc sound signal. |
