TFM/FMC

Araujo Engenharia brought to Brazil the most modern and precise technique in the area of phased array ultrasound for dimensioning discontinuities. The technique is able to focus on all points of a region of interest, ensuring an accurate image of discontinuities.

TFM/FMC – Total Focus Matrix / Full Matrix Capture, is an advanced ultrasonic inspection technique that uses arrays of transducers to collect data on the structural integrity of components. This technology is capable of providing detailed and accurate information on the presence of flaws, wear and corrosion in the early stages, with high detection and sizing accuracy.

The TFM/FMC technology is capable of generating 3D images and allowing real-time analysis, in addition, TFM/FMC can be used on a variety of materials, including metals, composites and ceramic materials.

FMC – Full Matrix Capture is a data acquisition process where each element of a transducer is used as a transmitter while all other elements are used as receivers for each transmitting pulse.

TFM – Total Focus Method is an electronic focusing process that consists of adapting the focal laws to focus on many points after a single pulse.

The result provides high resolution images with excellent scaling accuracy.

Araujo implemented the use of the TFM/FMC technique to solve problems such as the detection of surface cracks in equipment, as well as specific applications, such as a complementary technique for detecting and dimensioning damage by HTHA (High Temperature Hydrogen Attack).
