| Abstract: | The structure of pulsed MIG (metal inert-gas) welding equipment, which adopts inverter technology using IGBT, is designed based on DSP chip TMS320F2812 and mainly uced on aluminum alloys. Welding control system comprises hardware and software, using C language welding program, and it reduces difficulty of control system exploitation. Scheduling control, sampling disposal of feedback signals and digital PI modulation are achieved through program control, and this controls veraciously welding process. Experimental results validated that this welding equipment is character with high control precision and stability, it can obtain better appearance of weld. |
