At High Technology Nondestructive Testing Service Co., Ltd (HTNDT), we don’t just use technology—we build it. Our specialized engineering division focuses on the Design and Fabrication of Industrial Robots, as well as custom PAUT and ToFD Jigs and Fixtures, ensuring that even the most challenging inspection geometries are accessible and accurate.
Our Engineering & Fabrication Capabilities
1. Custom Robot Design & Prototyping
We develop robotic solutions designed to remove human inspectors from hazardous environments and increase data repeatability.
-
Remote Crawlers: Magnetic and vacuum-track crawlers for storage tank shells, wind towers, and large-diameter piping.
-
Autonomous & Semi-Automated Systems: Integrated motion control systems that ensure constant probe speed and pressure for high-quality ultrasonic data acquisition.
-
Bespoke Solutions: Designing “one-off” robotic platforms for subsea, high-elevation, or high-temperature inspection areas.
2. Specialized PAUT & ToFD Jigs and Fixtures
Standard scanners often fail on complex geometries. We fill that gap by engineering custom mechanical holders (jigs) and guiding systems (fixtures).
-
Geometry-Specific Scanners: Custom-contoured jigs for nozzle-to-shell welds, elbow-to-pipe joints, and small-bore tubing.
-
Multi-Probe Manifolds: Precision fixtures that allow for the simultaneous mounting of PAUT and ToFD probes, ensuring perfect alignment and “one-pass” inspection.
-
Encoder Integration: High-resolution mechanical encoders integrated into every fixture to provide 1:1 spatial mapping of defects.
Why Choose HTNDT Custom Tooling?
-
The “Un-inspectable” Made Possible: If a standard scanner won’t fit, our in-house team designs a solution that will.
-
Increased Data Quality: By eliminating the “human shake” of manual scanning, our robotic fixtures provide cleaner, more reliable A-scans and B-scans.
-
Rapid Turnaround: With our in-house fabrication shop, we can move from a CAD design to a physical prototype in days, keeping your project on schedule.
Technical Excellence & Innovation
Our design team consists of mechanical engineers and NDT Level III experts who understand the physics of ultrasound. This ensures that every robot and jig we build is not just a piece of machinery, but a precision scientific instrument.
-
Materials: Utilizing lightweight carbon fiber, aircraft-grade aluminum, and 3D-printed polymers for maximum durability and portability.
-
Compatibility: Our jigs are designed to be compatible with all major NDT platforms (Olympus/Evident, Waygate, Zetec, etc.).
