| 摘 要： | Robotic gas metal arc welding （GMAW） experiments were conducted using an ERTOS-1 electrode with Ar ＋ 10% CO2 shielding gas, and the welding current and arc voltage signals were collected by a data acquisition system. The boundaries between globular transfer and spray transfer in terms of the welding current and arc voltage were determined according to the waveform of electric signals and the Fourier transform results of arc voltage. The optimum welding parameters for the two transfer modes were obtained, which laid a foundation for the numerical simulation and control of GMAW process.
