Abstract

The phase transformation-generalized cross-correlation (PHAT-GCC) method was used to estimate the time delay of two acoustic signals. Then a robust regression method based on weighted least squares was used to obtain the time delay-deviation prediction model suitable for the low carbon steel butt pulsed metal-inert gas (MIG) welding process. Experimental results indicate that the time delay-deviation prediction model can meet the requirements of predicting welding path deviation.
