The invention relates to welding engineering and can be used for quality control of pin welding at compensator welding. It is based on extracting from acoustic signal harmonics is frequency range specific for material being welded, with determination of presence of second maximum in the signal being measured, comparison of amplitude values of the first and the second maxima to the values given.
