Ultrasonic device for non-destructive evaluation and quality inspection of resistance spot welds.
Resistance spot welding (RSW) joins car-body and chassis components, and weld quality directly affects vehicle safety and durability. The RSWA F2 uses a 52-channel ultrasonic matrix transducer to image the internal structure and surface of the weld, so operators can assess weld-nugget size and detect stuck welds, undersized nuggets and other defects on a colour touch screen — without destroying the part.
Because inspection is non-destructive and fast, RSWA reduces scrap, supports high sampling rates and gives feedback that keeps the welding process in control. The platform also evaluates adhesive joints and bonded assemblies.
Dedicated RSWA F2 transducers and a pencil probe extend the system to different weld sizes and access conditions. Typical applications include automotive body-in-white and chassis inspection, spot-weld audits, supplier quality control and adhesive-bond verification.
FAQ
Is RSWA testing non-destructive?
Yes. The weld is inspected ultrasonically and the part remains usable, unlike chisel or peel testing.
What defects can it detect?
Stuck welds, undersized or oversized nuggets, and other internal/surface weld defects, as well as adhesive-bond issues.
How is weld-nugget size assessed?
The 52-channel matrix transducer images the weld so the nugget area can be evaluated directly on screen.
Can it test adhesive joints?
Yes — the platform also inspects adhesive joints and bonded assemblies.
