Abstract :
A real-time synchronous acquisition and control system was designed to meet the requirements of measurement and control for pulsed MIG welding process of aluminum alloy using virtual instrument design software LabVIEW. Considering the characteristics of pulsed MIG welding, development efficiency and control response time, the mode of "data acquisition card+ PC+ real-time controller" was adopted and the parallel processing of voltage, current and vision signals was realized with complex signal processing algorithm based on hardware platform and COM technology. The test results show that the developed platform can acquire and process the information real-timely and effectively in pulsed MIG welding process of aluminum alloy and also has friendly program interface and good expansibility.
