In the dynamic arena of non-destructive testing (NDT), navigating the intricacies of austenitic steel weld inspections demands a fervent pursuit of innovation. Austenitic materials, with their coarse-grain structure, present unique challenges that only relentless problem-solving can overcome. This narrative unfolds against the backdrop of Eddyfi Technologies, where passion meets precision, education meets experience, and every stride is directed towards advancing productivity, saving lives, and protecting the environment.

Austenitic steel welds, a complex terrain within the NDT landscape, prompt a passionate quest for solutions at Eddyfi Technologies. The coarse-grain structure introduces challenges like high attenuation, grain noise, and redirection— complexities that demands a harmonious blend of innovation and precision. In our relentless pursuit, Eddyfi Technologies presents cutting-edge solutions that echo our commitment to innovation and problem-solving:

Dual 2D Matrix Array (DMA) Probes: Carefully designed, these probes operate at low frequencies (1.5 to 4 MHz), tailored for the intricacies of coarse-grain austenitic welds. The dual transmit/receive configuration, eliminates "ghost echoes" from the wedge, and enhances sensitivity and signal-to-noise ratio, or SNR.

Dual 2D Matrix Array (DMA) Probes

Linear Array ProbesIn the grand symphony of NDT, our linear array probes are used to inspect fine-grain base material and the heat-affected zone. For both probe types we can use Full Matrix Capture (FMC) and Total Focusing Method (TFM) to improve resolution and thus flaw detection and characterization capabilities.

High-Temp Dual Linear Corrosion ArrayImplementation of our solutions isn't just about technology; it's a carefully orchestrated practicality. The LYNCS™ CHAIN, an ode to innovative practicality, stands as the optimal scanning solution for austenitic pipe joints, transcending the limitations of traditional magnetic scanners.
