Abstract

In order to achieve the detection of welding defects, it is necessary to analyze the mechanism of sound source generation. The welding arc sound generation can be divided into two parts: one is a semi-transparent near-conical cavity enclosed by the protective atmosphere between tungsten electrode and welding test plate, which is excited by the sound source generated by the change in arc energy, and then sound source generation formed after the modulation of sound channel.
