Method for detecting arc weld faults

Weld quality is determined during the welding process involving a power/current source (22), a welding electrode, a base plate (26) and an electric circuit. The method includes the following steps: (a) sampling of a signal produced by the electrical circuit; (b) determination of the standard deviati...
