RSWA is an ultrasonic device designed for quality control and NDE of resistance spot welds. RSWA is as a portable andsimple-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 itwith prede ned 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 thenugget. 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 and continuous dataacquisition 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 reportingsystem and le 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
