05 May Stainless Steel Weld Inspection Made Easier Using Dual-Matrix Probes With Gekko

By Frederic Reverdy, M2M Product Sales Specialist at Eddyfi Technologies


Capture software has a library with existing DMA available from various vendors making the Gekko fully compatible with existing equipment.

Moreover, it is possible to completely configure DMA’s on the equipment. The operators can define the number of elements and the pitch in both directions making it possible for customers to define and test their own DMA solutions.

Delay laws are calculated on the equipment, so no need for an external software; this helps improves software ergonomics and productivity. All focusing options are available with DMA’s (learn more).

All the easy-to-use calibration tools like the TCG are also fully compatible with DMA’s (learn more).

As an example, we look here at a 35-mm thick stainless steel (316L) weld using an 8×4 dual-matrix array probe (DMA) at 2.5 MHz and longitudinal wedge. In the sectorial image, we can see the tip diffractions of a 10-mm notch located inside the weld. The dual-matrix probe, combined with the Gekko flaw detector is a very efficient solution for steel weld inspections.
