Abstract
A measuring device measures a state of a plurality of weld zones formed when a weldment is welded to a workpiece at a plurality of locations. This measuring device includes a plurality of application circuits that apply a current to each of one or more weld zones exclusively selected among the plurality of weld zones, and a detection circuit that detects a voltage obtained by combining voltages indicating magnitudes of voltage drops generated respectively by the plurality of more weld zones due to the application of the current. The measuring device further includes a processor that outputs information indicating the state of the plurality of weld zones on the basis of the voltages detected by the detection circuit.
