NextSpot 300

Phased Array Ultrasonic Spotweld Detector

Portable & Convenient

Real-Time Detect

Multi-Channel Phased Array System

Low Power Consumption


NextSpot 300 ultrasonic flaw detector will handle all your spots weld NDT needs, whether it is in production lines or in field environments. With all the same benefits, features, and functions as the 600, minus the monitor, the NextSpot 300 gives you great flexibility and portability by allowing you to plug into any PC laptop to convert into a fully functional NextSpot 600.

Key Features


NextSpot 300 is a powerful ultrasonic spotwelding inspection system that is suitable for the flexible collaboration with varies computing systems.

Tough & Rugged

NextSpot 300 is designed with 360° shielding, it adopts an one-piece aluminum alloy and covered with rubber protections. It is rugged, lightweight, and compact. The total weight of the body is about 2kg.

Compact yet Powerful

NextSpot 300 is compact but it has the same ultrasonic specifications and inspection capabilities as well as that of NextSpot 600.

Flexible for varies applications

NextSpot 300 is flexible for varies utility scenes,and it can be embedded and integrated with the unique inspection systems that tailor-made by the end users.

Low Power Consumption

NextSpot 300 is efficient and low power consumption, it only needs to get power from the PC,laptop or a computer workstation via a piece of USB 3.0 cable.

Solution for Big Data Analysis and Smart Spotwelding Inspections

NextSpot 300’s database technologies allow efficient data uploading to NAS servers for big data analysis. The analysis of spotwelding quality inspection data can be linked with the welding process data records of every single welding Spots, therefore the optimizations of the welding process setting will be supported with huge volume of inspection data.

Real-time Imaging and Other Testing Methods

NextSpot 600 can provide A/C - scan and real-time display on spot weld. NextSpot 600 can support single element probe testing, PA imaging testing as well as various nonultrasonic methods, data capture, chisel inspection, visual inspection, and many more.

NextSoft Studio

NextSoft Studio Admin

Each NextSpot 600 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 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.
