Abstract: The realization of microcomputer test and analysis system for CO2 arc welding
dynamic process based on built-in assembler was deeply analyzed . The system based on built-in assembler program which can optimize the key object code such as port-read , frequency spectrum analysis and so on makes user test the welding process high-speedly ,real-timely and accurately. With the function of data displaying and data processing ,the system represented the characteristic of the signal of welding dynamic processing both in time domain and frequency domain. It satisfied the function and performance requirement and provided an efficient tool for researching the welding process, The test result of the system was well.
Keywords: built-in assembler; welding dynamic process; test; frequency spectrum analysis
