eddy current machine

4. Main Components

1. High-Frequency Power Supply: Generates excitation current for the probe.

2. Eddy Current Probe (Coil): Induces and detects eddy current changes.

3. Signal Amplifier & Processor: Amplifies and filters detection signals.

4. Alarm Unit: Provides audio/visual alerts for defects.

5. Display and Control Panel: Interface for monitoring and parameter adjustment.

6. Mechanical Fixture: Holds and positions the probe relative to the pipe.

5.Application in Welded Pipe Equipment

1. Post-Weld Inspection:
   The eddy current tester is installed after the welding stage but before sizing, to inspect weld seams in real time.

2. Continuous Online Testing:
   As the pipe moves through an encircling coil probe, the device continuously scans the weld area for flaws.

3. Real-Time Alarm and Rejection:
   When a defect is detected, the system triggers an alarm and can activate an automated rejection mechanism to remove the defective pipe.

6. Operating Procedure       

1. Installation & Calibration

   • Install the probe on the production line (typically after welding).

   • Adjust probe-to-pipe gap for optimal sensitivity.

2. Parameter Setup

   • Set frequency, gain, and filters according to pipe size and material.

   • Calibrate using standard defect samples.

3. Start Testing

   • Start both the flaw detector and production line.

   • The system performs real-time inspection of the pipe surface and weld seam.

4. Defect Alarm & Handling

   • If a flaw is detected, the system triggers an alarm.

   • Defective pipes are automatically rejected via a mechanical system.

5. Data Recording & Analysis

   • Test data can be saved for traceability.

   • Statistical reports can be generated for quality improvement.

7. Factors Affecting Test Performance

• Operating Frequency:
  High frequencies detect surface flaws; lower frequencies penetrate deeper.

• Material Type:
  Different conductivity and magnetic permeability affect eddy current response.

• Probe Design:
  Must match pipe diameter and weld location.

• Speed & Stability:
  High-speed operation requires stable signal acquisition and precise mechanical setup.

🔁 Summary

The core principle of eddy current testing is:
“Defects disturb eddy currents → Eddy currents alter coil impedance → Electrical signal changes are detected and analyzed.”
It is a non-contact, high-speed, and highly sensitive method ideal for inline weld inspection in pipe manufacturing.
