Aolong AL-GB-1306 High-Frequency High-Voltage Generator for Portable X-ray Radiography

Overview

The Aolong AL-GB-1306 is a compact, high-frequency high-voltage generator engineered specifically for portable industrial X-ray radiographic inspection systems. It operates on solid-state inverter technology to convert low-voltage DC input into precisely regulated high-frequency AC, which is then stepped up via a high-efficiency high-voltage transformer and rectified to deliver stable, ripple-free DC output to the X-ray tube. This architecture enables superior voltage/current stability, rapid response to load changes, and minimized thermal drift—critical for consistent image contrast and defect detectability in weld integrity assessment. Designed for field-deployable non-destructive testing (NDT), the generator supports real-time adjustment of tube voltage (30–130 kV) and tube current (0.1–0.6 mA), allowing operators to optimize exposure parameters across a broad range of material thicknesses and densities—including stainless steel, carbon steel, and nickel-based alloys commonly found in heat exchanger, boiler, and pressure vessel tube-to-tubesheet joints.

Key Features

• High-frequency inverter topology (20 kHz switching frequency) ensures reduced magnetic core size, lower audible noise, and improved power conversion efficiency compared to conventional 50/60 Hz transformers.
• Compact cylindrical form factor (Ø225 × 785 mm) and lightweight design (23 kg) facilitate manual handling and integration into mobile inspection carts or confined-access workspaces.
• Intelligent digital control panel with intuitive interface provides real-time monitoring of kV, mA, exposure time, and system status; includes programmable exposure presets and password-protected parameter locking for QA/QC compliance.
• Dual-stage safety architecture: hardware interlocks (e.g., overvoltage, overcurrent, overheating, and tube arcing detection) combined with software-enforced exposure limits per IEC 61331-1 and GBZ 138–2019 requirements.
• Modular high-voltage cable interface compatible with multiple industry-standard X-ray tube assemblies (e.g., Comet MXR, YXLON TITAN, and domestic equivalents), enabling flexible configuration for varying focal spot sizes and heat dissipation needs.

Sample Compatibility & Compliance

The AL-GB-1306 is validated for use with sealed-tube industrial X-ray sources rated for ≤130 kV and ≤0.6 mA, particularly those optimized for high-resolution weld radiography (e.g., 0.4–1.0 mm focal spots). Its adjustable output characteristics support ASTM E94/E1742-compliant radiographic sensitivity verification using penetrameters (IQIs) across thickness ranges from 3 mm to 80 mm steel equivalent. The generator meets electromagnetic compatibility (EMC) requirements per EN 61326-1 for industrial environments and incorporates radiation safety features aligned with national regulatory frameworks including China’s GBZ 138–2019 and international guidance from the IAEA Safety Standards Series No. SSG-11. All operational logs—including exposure history, fault events, and parameter changes—are timestamped and retained onboard for GLP/GMP audit readiness.

Software & Data Management

The integrated controller firmware supports RS-232 and optional Ethernet communication protocols for remote operation and data logging. Exposure parameters and event logs can be exported in CSV format for traceability in quality management systems (QMS). While the generator itself does not include proprietary imaging software, its API-compatible interface allows seamless integration with third-party digital radiography (DR) acquisition platforms—including DICONDE-compliant viewers—and enterprise-level NDT reporting tools compliant with ISO 17025 documentation requirements. Audit trail functionality records user ID, timestamp, and parameter modifications—supporting FDA 21 CFR Part 11 principles where electronic records are employed in regulated manufacturing contexts.

Applications

• Non-destructive evaluation of tube-to-tubesheet welds in shell-and-tube heat exchangers, steam generators, and condensers.
• In-situ radiographic inspection of piping welds in petrochemical, nuclear, and power generation facilities where fixed X-ray rooms are unavailable.
• Field verification of weld penetration, lack-of-fusion, porosity, and cracking in ASME Section IX and ISO 5817 Class B/C weldments.
• Quality assurance during fabrication of pressure boundary components under PED 2014/68/EU or NB-23 jurisdiction.
• Support for computed radiography (CR) and amorphous silicon flat-panel detector (FPD) workflows requiring stable, low-ripple high-voltage excitation.

FAQ

What X-ray tube models are certified for use with the AL-GB-1306?
The generator is electrically and mechanically compatible with any industrial X-ray tube rated for 30–130 kV and 0.1–0.6 mA, provided it uses a standard high-voltage connector (e.g., SHV or MHV) and meets thermal loading specifications. Common integrations include Aolong’s own AL-TT series tubes and third-party equivalents meeting IEC 60522 mechanical and electrical interface standards.
Does the AL-GB-1306 support pulsed or continuous operation modes?
It operates in continuous-duty mode with a 1:1 duty cycle rating; however, exposure timing is fully programmable down to 0.1 s increments, enabling short-pulse exposures suitable for minimizing motion blur in handheld applications.
Is firmware upgrade capability available?
Yes—firmware updates are delivered via USB flash drive and performed through the front-panel interface, with version rollback and checksum validation to ensure integrity and regulatory traceability.
What environmental conditions are specified for field operation?
Rated for ambient temperatures from –10 °C to +40 °C and relative humidity up to 85% non-condensing; IP54-rated enclosure provides protection against dust ingress and water splashing during outdoor or workshop deployment.
Can the generator be integrated into automated inspection systems?
Yes—its RS-232 serial interface supports Modbus RTU protocol for integration with PLC-controlled positioning rigs, robotic arms, or conveyor-based DR lines, enabling repeatable, process-locked radiographic workflows.
