Mastering the Art of Spot Weld Inspection: Meet the Tessonics RSWA F-2

Mr. Rouse March 9, 2026

In modern automotive and aerospace manufacturing, the integrity of a resistance spot weld (RSW) is non-negotiable. With thousands of welds per vehicle, traditional "hammer and chisel" destructive testing is no longer sustainable—it’s slow, wasteful, and only provides a statistical snapshot of quality.

Enter the Tessonics RSWA F-2, the next generation of portable ultrasonic spot weld analyzers. Built on the field-proven success of its predecessor, the F-1, the RSWA F-2 is thinner, lighter, and smarter, setting a new gold standard for Non-Destructive Evaluation (NDE).

What Makes the RSWA F-2 Stand Out?

The F-2 isn't just a simple ultrasonic gauge; it is a sophisticated imaging platform. By utilizing multi-channel ultrasonic matrix array technology, it allows engineers to "see" inside the weld nugget without damaging the part.

1. High-Resolution Matrix Imaging

Unlike traditional single-element probes, the F-2 uses a matrix transducer (available in 52 or 120 elements). This creates a detailed 2D C-scan image of the internal weld structure in real-time. You can instantly see the nugget’s shape, size, and any internal defects like porosity or "stick welds."

2. Intelligent AI Algorithms

The software is the "brain" of the F-2. It automatically estimates the average nugget diameter and compares it against your pre-defined quality specifications. Whether you are welding 2T or 3T (two or three-layer) stacks, or working with Steel and Aluminum, the F-2 provides a clear "Go/No-Go" result.

3. Built for the Shop Floor

Manufacturing environments are tough, and the F-2 is designed to thrive in them:

  • Portability: Weighing only 2.3 kg (5 lbs) with an 11-hour battery life, it’s perfect for all-day line audits.

  • User-Friendly Display: A high-resolution 10.1” touch screen provides crystal-clear graphics that are easy to interpret even for non-experts.

  • Pencil Probe Option: For those hard-to-reach areas, the F-2 supports a slim "Pencil Probe" designed to fit exactly where a welding electrode would.

Why It Matters for Industry 4.0

Quality control is no longer just about catching mistakes; it’s about data. The RSWA F-2 integrates seamlessly with the Tessonics Data Service (TDS), allowing for wireless data synchronization and centralized reporting. This connectivity ensures that every weld’s "digital birth certificate" is stored and traceable, supporting the high standards of smart factories.
