	Finding poor-diffusion bonds in ferrous, nonferrous tubes: Pursuing, preventing pasty welds By: John Wallace 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. Publish date: December 11, 2007 Tech cell: Testing and Measuring
