Abstract: In order to keep the stabilization of GMAW-P weld, the new
welding current waveform of GMAW-P welding and the self-adjusted fuzzy
control system is designed. Which uses the arc voltage as the under
controlled parameter, the base time and wire-feed speed as the control
parameters. The result shows that this control system responds quickly
with high control precision and can control the arc voltage steady.
Key words: GMAW-P welding Welding current waveform Arc voltage Fuzzy
