In this paper, the influence of pulse parameters at various torch angles on the tensile properties of low carbon steel butt weld in pulsed metal inert gas welding was studied and an infrared pyrometer and sound sensor have also been used along with arc sensors to monitor the weld quality.Abstract:
The present work focuses on the influence of pulse parameters at various torch angles on the tensile properties of low carbon steel butt weld in pulsed metal inert gas welding. The interface of weld zone and heat affected zone was found to be the weakest area due to significant variation of weld microstructure. The weld bead characteristics strongly influenced the joint strength. An infrared pyrometer and sound sensor have also been used along with arc sensors to monitor the weld quality. The arc power and arc sound kurtosis were found to be strongly correlated with weld quality.read more
