Method and apparatus for inspecting weld quality

摘要

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.

1. A method for inspecting the quality of a weld under test in a structure having a plurality of spaced apart welds comprising the steps of:
placing two probes on opposite sides of the structure so that a current path is formed through the weld under test, energizing the probes with alternating current at least one known frequency, measuring magnetic flux generated from current flow through said probes and at least one spaced apart weld, comparing said measured magnetic flux with previously determined data representing weld quality to thereby determine the weld quality of the weld under test.
