RSWA F1Resistance Spot Weld Analyzer
RSWA F1Resistance Spot Weld Analyzer
The RSWA F1 is a portable ultrasonic inspection device for non-destructive quality evaluation of resistance spot welds. Using a multi-channel matrix-array transducer, it provides real-time imaging of the internal weld structure and automatic estimation of weld nugget diameter.
Designed for 2T and 3T steel sheet assemblies, including mild, high-strength and dual-phase ultra-high-strength steels, the RSWA F1 is particularly suitable for automotive production and quality control of spot-welded structures.
Description
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.
