F2 Platform

Ultrasonic Quality Inspection Platform

F2 is an ultrasonic device designed for NDE and quality control for various applications, including resistance spot welds, and adhesive joints. Using the unique technology of multi-channel ultrasonic matrix arrays, this portable and simple-in-operation device is capable of producing internal ultrasonic C-scan images of defects and structures.

Our algorithms evaluate the quality determining features that can be compared to predefined specifications. To further improve the operator’s experience, our software assists in making decisions in automatic or semi-automatic mode, guides through the inspection routines with easy to understand graphics, stores the record of the inspected parts and integrates into a larger infrastructure with centralized inspection planning and reporting.

    Resistance Spot Weld Analyzer
    RSWA is an ultrasonic device designed for quality control and NDE of resistance spot welds. RSWA is as a portable and simple-in-operation device capable of producing images of spot weld’s internal structures. In addition to live on-screen image, this device performs estimation of the nugget diameter and compares it with predefined minimum nugget requirements.

    Using the unique technology of multi-channel ultrasonic matrix transducer, RSWA collects data from the surface and from the internal structures of the nugget. Special algorithms use this data to reconstruct the image of the spot weld and estimate the average diameter of the nugget area in real time.
  • Single-frame and continuous data acquisition modes
  • Automatic and manual nugget size estimation
  • Automatic detection of scanning depth inside the metal
  • Two levels of user interface complexity depending on operator skills
  • Built-in reporting system and file storage
  • Application
  • Metal stacks: 2T and 3T; 0.6 – 2.4 mm plate thicknesses
  • Types of materials: mild steel, high strength steel, dual phase ultra high strength steel
  • Coatings: bare, zinc coating (galvanized, galvaneal), e-coating, paint
  • ABIS

    Adhesive Bond Inspection System
    ABIS is a software extension for our RSWA instrument and was developed to test adhesion bonds, e.g. hem flanges in the automotive industry, non-destructively. The software follows the operating concept of the RSWA-GUI and therefore offers an easy switch-over.

    ABIS displays adhesive coverage in a structure as a so-called C-scan, an planar top-view display. Thus, the operator is quickly ablte to determine position, orientation and extension of imperfections in his adhesive bond.

    Industrial Ultrasonic Couplant
    Our goal in developing and producing IMAGEL is to employ acoustic coupling with high impedance to improve imaging quality for NDE in the automotive and aerospace industry. Other currently used ultrasonic coupling gels are mostly water-based which only yield an acoustic impedance of 1.48 · 106 kg/(m2s). They are not very suitable for metals where the numbers are much higher (steel: 4.5 · 107 kg/(m2s), aluminum: 1.7 · 107 kg/(m2s).)

    For a thin layer of coupling between the transducer and inspected body, its influence is not very important. However, for rough metal surfaces, such as deep indentations at spot welds, the gel's thickness may reach 1 mm. This makes the acoustic impedence of the coupling significant as mismatches between acoustic impedances create strong ultrasound reflections from both surfaces. Thus, acoustic coupling gels with higher impedances that more closely match the acoustic parameters of the metal help to improve the quality of acoustic imaging.

    The glycerol-based IMAGEL has a density of 1.18 g/cm3 and an acoustic impedance of 2.39 · 107 kg/(m2s) which corresponds well to the material of the transducer tip (delay lines). That matching eliminates reflection on the delay line to gel boundary and reduces the reflection signal on the gel to metal boundary. The viscosity of the gel is maintained in the range of 30 - 40 kcPs to prevent gel sliding down from inspected areas on inclined surfaces. Also, the gel's composition includes a preservative to maintain its quality through its life-time (2 years) and a corrosion inhibitor to eliminate metal degradation.
