Abstract
This paper describes the CO2 gas shielded arc welding droplet transfer basic theory. It describes the current waveform control scheme welding process in making a variety of droplet transfer mode on the basis of which focus on the STT Surface Tension Transfer Theory and welding power source voltage and current waveforms. Design of CO2 gas shielded welding droplet transfer current waveforms used. Describes common microcomputer chip DSP and major structural features of the microcontroller and microcontroller C8051, C8051 software instruction processing speed and computing capacity. Using C8051 MCU in the establishment of a waveform control model based on the design by the associated software program in order to achieve accurate real-time waveform control. These results indicate that the waveform control scheme designed to enhance the stability of welding reduces spatter produced improved weld. This paper describes the design process of the waveform control programs and software systems. [资料来源：http://www.THINK58.com]
