Investigation of CO_2 Welding Arc Sound : Correlation of Welding Arc Sound Signal with Welding Spatter(Physics, Processes, Instruments & Measurements)
Search this Article
A computer detection and analysis system has been developed and the correlation of CO_2 welding arc sound with spatter loss as well as other affecting factors was studied. The results show that the welding spatter loss is proportional to the arc sound energy produced at the end of short circuit transfer. Based on this discovery, a new sensing method is proposed to characterize the CO_2 welding spatter loss on line by means of the arc sound energy signal.
