Mitech XXQ-2005 X-ray Flaw Detector

Mitech XXQ-2005 X-ray Flaw Detector

Product Overview

The Mitech XXQ-2005 is a high-performance portable X-ray flaw detector designed for non-destructive testing (NDT) of internal structural defects in metal and other solid materials. Utilizing the principle of X-ray absorption, this device reveals internal anomalies such as cracks, inclusions, and porosity by detecting differences in material thickness and density.

Its compact, inflatable-tube design, lightweight body, and user-friendly interface make it highly effective for on-site inspection work—even in harsh, elevated, or generator-powered environments. The XXQ-2005 provides high-definition imaging directly on X-ray film, enabling reliable long-term documentation and defect assessment.

Applications

The XXQ-2005 is widely used in:

• Shipbuilding and marine structures

• Aerospace and aviation industries

• Railway and transport component inspections

• Pressure vessel and boiler manufacturing

• Oil and gas pipelines

• Petrochemical and chemical processing

• Machinery manufacturing

• National defense and military production

Working Principle

The device operates by generating X-rays that pass through the test object. Areas with different thicknesses or densities absorb the rays differently. These variations are captured on a special radiographic film that, after development, visually displays internal flaws as contrast differences.

The system uses a silicon-controlled rectifier (SCR) and a single-phase bridge rectifier to convert AC to DC. A high-voltage pulse is generated using a thyristor chopper and sent to the X-ray tube, where high-speed electrons strike the anode to emit X-rays. These rays pass through the material and imprint an image on the X-ray film enhanced with lead foil.

Key Features

• microcomputer-controlled system for precision and operational efficiency

• compact and lightweight for convenient field use

• automatic over-temperature shutdown to protect internal components

• pulse-regulated current control (mA) for stable X-ray intensity

• continuously adjustable tube voltage (kV) to meet varying material needs

• built-in anti-interference circuitry to stabilize performance

• automatic fault code display for quick troubleshooting

• enforced 1:1 operation-to-rest duty cycle for system longevity

• delayed high-voltage start for operator safety

• isolated high-voltage system for safe, reliable operation

• compatible with generator-powered setups for remote use

Operating Environment

• operating temperature: -25°C to 40°C

• relative humidity: ≤ 85%

• safe operating pressure: 0.35–0.50 MPa

• do not operate below 0.35 MPa

Operating Instructions

• turn on the device and wait for initialization (approx. 15 seconds)

• set exposure time, kV, and mA according to the material under inspection

• warm up the tube before initial exposure to ensure vacuum stability

• press “HV ON” to initiate delayed high-voltage output

• after exposure, the system will automatically shut down and enter rest mode

• develop X-ray film and inspect for flaw indications

Troubleshooting & Maintenance

Do not disassemble or repair the unit. Contact Mitech’s authorized service team for any issues.

Common faults and solutions:

• no display or fan: possible cable disconnection, faulty switch, or blown 3A fuse

• error code “LA”: no tube current; may be caused by poor connection or blown 20A fuse

• error code “HA”: overcurrent protection triggered

• error code “PU”: overvoltage detected

• error code “PT”: unit overheated

• fuse blows or loud buzzer on HV activation: internal air pressure may be too low, or generator/controller failure

• electric leakage: check for grounding issues or insulation damage

The Mitech XXQ-2005 is an effective and dependable X-ray flaw detection solution built to meet the rigorous demands of industrial NDT.
