Abstract
An apparatus and method for inspecting the quality of a weld under test in a structure having a plurality of spaced apart welds. Two probes are placed on opposite sides of the structure so that a current path is formed through the weld under test. The probes are energized with alternating current at a known frequency. The magnetic flux generated from the current flow through the probes and at least one of the spaced apart welds is then measured and subsequently compared with magnetic flux data previously determined and representing weld quality.
