RSWA F1 Resistance Spot Weld Analyzer

Published May 5, 2017

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.

Features:

◾single-frame and continuous data acquisition modes
◾automatic and manual nugget size estimation
◾automatic detection of scanning depth inside the metal
◾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
◾Coatings: bare, zinc coating (galvanized, galvaneal), e-coating, paint
