Determining whether a tube seam has a partial bond can be difficult with standard ultrasonic or eddy current techniques. However, multifrequency, probe-based eddy current equipment can detect poor-diffusion bonds in nonferrous materials. Using a penetrating field to reflect a signal off the planar structure of the weld works on ferrous materials.
