  • Real-time resistance spot welding process control by using acoustic detection. IIS/IIW Doc. III-1194-01
    Gorkič, Aleš ...
    In this contribution, low frequency sound emitted durign resistance spot welding of mild steel is examined. In addition to sound detected by a capacitive microphone welding current and electrode ... movement were monitored in several welding regimes which differed in intensity of heat input. It is demonstrated that it is possible to determine expulsion initiation and intesity by means of analysis of detected sound signals. On this basis, a method for determination of the upper limit of acceptable welding parameters is proposed.
