800 All


Introducing the NextSPOT 800. By leveraging the many years of experience and expertise to inspect spot welds in the NDT industry, we have upgraded the 800 with the latest state-of-the-art hardware and software and integrated it with a TFM/FMC scanner with real-time 3D scanning capabilities. The new system is the best-of-class ultrasonic flaw detector to handle all your automotive spots weld NDT needs, whether in production lines or field environments.

In today’s ever-increasing competitiveness in the automotive manufacturing segment, NextSPOT 800, its easy-to-use and powerful feature interface can save valuable time and hugely increase productivity.

Key Features - Spot Weld Inspection

Real-time Imaging and Other Testing Methods

NextSpot 800 can provide A/C - scan and real-time display on spot weld. NextSpot 800 can support single element probe testing, PA imaging testing as well as various nonultrasonic methods, data capture, chisel inspection, visual inspection, and many more.

Accurate Measurement - 64 Channels, 1MHz-25MHz Bandwidth, 400 Mhz/12 bits DSP

By adopting a parallel 64 channel design, 1MHz-25 MHz analog bandwidth, and 12 bits DSP, it gives NextSpot 800 the most accurate measurement of welding nuggets and indentations. Furthermore, the results are all visual and can be immediately determined whether the results are passed or failed.

NextSoft Studio

NextSoft Studio - Spot Weld

Each NextSpot 800 comes with the standard version of the our NextSoft Analyser System, which works well as an independent stand-alone spot weld inspector. But often NDT inspections require to function as a group or a team that is supervised by management. The NextSoft Studio Admin (software) provides this function.

The admin version can upload any testing required part images into the system. The system can then create visual labels on exactly where and what to test, and also setup the testing sequences. All inspection points’ results will then be individually captured and logged into a database for further statistical evaluation.


NextSOFT Studio - TFM/FMC

NextSCAN includes NextSOFT, our time-tested, powerful, yet easy-to-use software. NextSOFT has many advanced features and functions to assist in capturing all your Parallel PA & TFM UT signals. Most importantly, NextSOFT delivers to you the highest real-time 3D imaging and resolution the industry has to offer with many options via A, C, and S scans.


NextSoft Studio Cloud - (Optional)

Our NextSoft Studio Cloud is a cloud data managment tool that can synchronize data among multiple units of NextSpot 600 devices via the cloud to a single repository location.

In order to manage a full team of inspectors in a production line and/or in a field environment that meet strict quality NDT management requirements, all data captured by each NextSpot 600 unit can be individually upload data to a cloud based data repository along with information such as inspection plans, test location, test settings, and etc.

Once the data are in the cloud repository, they can be downloaded into a remote management system off-site for further analysis.
