RSWA F2 – Ultrasonic quality inspection platform
RSWA F2 is an ultrasonic device designed for non-destructive evaluation and quality inspection for various applications, such as spot welds and adhesive joints testing. RSWA F2 is a result of the systematic advanced development of the field-proven and successful RSWA F1 from Tessonics. F2 device is 50% lighter and thinner and provides unique ease of use due to the high-resolution 10.1″ display and the possibility for wireless connection to new Tessonics Data Service.
The Tessonics Data Service (TDS) is a data management software that provides the possibility to manage all connected RSWA F2 instruments and to keep software revisions up-to-date. Additionally, measurement data can be made available – almost in real-time – to any user within a network and appropriate authorization. For this, no additional software is required, the user can directly access data with every internet capable device.
Together with the RSWA F2, a new and unique transducer technology is introduced. While for comparable instruments on the market the complete transducer has to be exchanged in case of a defect cable, cables can be replaced on RSWA F2 transducers separately which reduces maintenance costs significantly.
The unique technology of multi-channel matrix arrays allows the portable and ease to use device to produce internal ultrasonic C-scan images of defects and structures. Tessonics algorithms evaluate the quality determining features that can be compared to predefined specifications. To further improve the operator’s experience, the software assists in making decisions in automatic or semi-automatic mode, guides through the inspection routines with intuitive graphics, saves the record of the inspected parts and integrates into a large infrastructure with centralized inspection planning and reporting.
- Resistance Spot Weld Analyzer (RSWA)
- Adhesive Bonding Inspection System (ABIS)
- transducers with built-in identification system
- unrestricted matrix element count
- single-frame and continuous data acquisition modes
- standard 52-element transducer
- new 120-element with 15 mm diameter coverage

RSWA F2
RSWA F2 Transducers
For the RSWA F2 a unique transducer technology has been developed that provides the possibility to replace cables in case of damage. The cable can be replaced by the operator by simply loosening respective screws which significantly lowers maintenance costs.
The RSWA F2 transducers are available in a 52-element or in a new 120-element version.
- Matrix-array transducer
- 52 or 120 elements (diameter: 10 or 15 mm)
- 1,25 mm x 1,25 mm pitch
- 15 MHz
- 2 m cable length
- replaceable hard delay line
- replaceable cable, same cable type for both transducer versions

Pencil Probe
The Pencil Probe for RSWA F-2 enables testing even in hard-to-reach places. With its housing diameter of only 16 mm and the length of 100 mm it is designed in the shape of a welding electrode and therefore also reaches deep positioned spot welds.
With its 52 elements with the pitch of 1.25 x 1.25 mm it has the same ultrasonic characteristics as Tessonics proven RSWA standard probes.
In addition, the probe has also the option of replacing the cable in the case of damage without having to replace the entire probe. The probe and cable are simply connected to one another by industry-proven Lemo connectors.
Features
– Matrix-array transducer
– 52 elements (diameter: 10 mm)

– Replacable hard delay line
– Replacable cable, Lemo connector
ABIS
The Adhesive Bond Inspection System (ABIS) was developed by Tessonics Inc. for NDT of adhesive joints in automotive and aerospace assemblies. This system employs a matrix array of small flat ultrasonic transducers for evaluation of the adhesive joint. The reverberating waveforms recorded by the array elements are processed to obtain an informative parameter, whose two-dimensional distribution is presented as a C-scan. The C-scans show the lateral location of “adhesive/no-adhesive” regions in the joint.

RSWA F1 – Resistance Spot Weld Analyzer
RSWA F1 is an ultrasonic device designed for non-destructive evaluation and quality inspection of resistance spot welds.
RSWA F1 from Tessonics is a portable and easy to use device capable of producing images of spot weld’s internal structures. In addition to live on-screen image, the device estimates 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.
Features
– single frame a 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
Applications
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

Purpose
The detector is designed specifically to detect flaws in waterproof coatings on conductive substrate (e.g. steel, concrete, aluminium foil) of roof systems with the application of high voltage while an electric spark is fixed by the device in the place of the fault.
This dry method does not require wetting the waterproof membrane surface before the test, which allows to inspect both flat and complex-shaped surfaces with a significantly higher speed.

— quick battery replacement;
— battery charging in the device or separately while using the device (two batteries in the delivery set);
— high safety due to pulsed operation mode;
— large selection of replaceable electrodes for different purposes;
— small dimensions and light weight;
Basic technical characteristics
— Type of indication of voltage amplitude on electrode– digital (3-digit);
— Output voltage adjustment resolution: 0,1 kV;
