A System For Real Time Monitoring Of Successive Reference Welds

A System For Real Time Monitoring Of Successive Reference Welds Produced In An Arc Welding Procedure

Abstract: The invention relates to a system for real time monitoring of successive reference welds produced in an arc-welding procedure comprising an arc voltage sensor, and an welding current sensor for acquisition of voltage values (V) and of current values (1); and an apparatus for said voltage values (V) and said current values (1) to derive statistical parameters, and further processing the values to obtain a probability density distribution for the reference welds and performing real time monitoring of the welds for identification of welding defects by comparing the instable weld signatures with the acceptable weld signatures of the reference Probability Density Distribution curves (PDD).
