FAAST PA - When Speed is needed


FAAST-PA is a Phased Array instrument (PAUT) which is much more powerful than any conventional phased array electronic.

Thanks to its sinusoidal pulser and its real time data processing software, the FAAST has the capability to transmit multiple sound beams, multi-oriented and/or multi-focused, using multi-element probes with only one single shot, and then to process signals received from all beams in real time.


This patented technology (WO 03029808) revolutionizes the NDT field when speaking about UT inspection thanks to its high speed testing capabilities, as it is able to replace several conventional Phased Array systems running in parallel. It offers even more than speed as it also reduces the number of phased array probes, mechanical parts, maintenance and calibration time.

The FAAST technology can be applied to any type of application (tubes, bars, plates, aircraft components, railroad, etc…), on different materials (Titanium, Aluminium, Steel, Special Alloy, Copper, Composites, etc…) and in any industries.

FAAST PA concept

Thanks to the FAAST PA technology you can combine all the delay laws within one shot.

FAAST PA concept

Multi angle shot

The multi-angle is one of the prominent capabilities of our Phased Array FAAST (PAUT) for generating multiple beams using a multi-element probe and up to 64 beam orientations or even more, are generated simultaneously in one single shot. Signals are processed in real time, up to 64 directions simultaneously, but this does not restrict the number of beams. This advanced acquisition mode can be used with either 1D linear probe or 2D Matrix multi-element probe

Multi focus shot

The multi-focal is one of the other prominent capabilities of our UT FAAST Phased Array (PAUT) system allowing the generation of multifocal beams through a multi-element probe in one single shot.

The principle of Phased Array is to calculate the delay laws to focus at a given depth and/or angle and this method is usually used with either 1D linear or 2D matrix multi-element probes.The advantage of Phased Array compare to mono-element, cylindrical or spherical focusing, is the possibility to calculate the delay laws by Software instead of having a concave probe for each focus depth.

When considering the multizone testing with 1 multi-element probe, 1D or 2D matrix, the Multi-focal advanced acquisition mode from the  FAAST PA is a real strength as it allows the reduction of the number of required shots due to its capacity to transmit multiple focal delay laws in one shot.

Multi frequency shot

The FAAST PA offers also the possibility to shot at different frequencies (within the bandwidth of the probe) using the same probe, and firing simultaneously. For example, this is useful to generate 0° ultrasound beams at 5MHz and 7MHz in one single shot.

For pipe inspection, we have used the multi-frequency features using a 1D linear multi-element probe, meaning that with one probe, we are able to make wall thickness measurement at 5MHz, and delamination inspection at 7.5MHz, within 1 single shot and using only 1 probe.

Advanced DDF

The advanced DDF is a FAAST features using the multi focus shots. It allows you to perform only shot to inspect several zones.

As you can see on the picture we are able to receive using the DDF methods as any phased array instruments would but we can also trasmit in parallel and in one shot.

This is how you can gain a lot of time when inspecting thick parts

You can see below how accurate you can be when using the FAAST PA Advanced DDF. But even importantly you inspect your parts way faster !

UT View


UTView is the API’s delivered with all Socomate International’s products and which is compatible with both conventional UT and PAUT instruments. The software provides an A-Scan view and allows to set all UT parameters.

UTView Software is provided with the source codes for you to integrate your Company logo or customize it as you like!

For more information, please feel free to contact us to get a full presentation.



SIPAtools is a specific software, developed by Socomate International and delivered with all Phased Array instruments used to define and calculate delay laws for any applications.

The software offers several possibilities:

  • Design a probe
  • 2D and 3D view of the probe
  • Define the UT beam according to the part to inspect

Customized Application Software


Thanks to our open platform product, take advantage of the most complete DLL to develop your own customized software in any languages available that work on Win7 and Win10 operating systems, 32 and 64 bits.

The most standard languages such as C++Visual Basic or LabView, benefit concrete example of coding with Socomate International DLL. The advantages of making its own application software is to perfectly meet your customers’ requirements instead of providing a standard and often complex software. Socomate’s DLL is compatible for both complete range of conventional UT and PAUT equipments, avoiding redundant work when involved in various applications. Having a common DLL for all products makes it more comfortable !
