Spot Weld Inspection

Tessonics RSWA F1

Resistance Spot Weld Analyzer

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

 • The 52 A-scans are processed and evaluated separately to build a final C-scan image with a color scale assigned

   to each element’s echo amplitude

 • Probe technology provides the capability to build a C-scan image with the following estimated dimensional values. Spot weld nugget

   diameter, weld nugget indentation depth and spot weld nuggget thickness from the center of weld nugget

 • The RSWA provides software for the user to build custom sequenced inspection plans for each part and spot weld

 • Software deals with different surface profile conditions encountered with spot weld testing.

 • Re measurement software with complete tracebility

 

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
