Eddy Current Testing Machine


Main Applications

The Eddy Current Testing Machine is mainly used for:

  • 🔹Weld seam inspection of ERW steel pipes

  • 🔹Detection of surface and near-surface defects

  • 🔹Online quality control during high-speed tube production

Typical defects detected include:

  • 🔹Cracks

  • 🔹Pinholes

  • 🔹Incomplete welding

  • 🔹Surface scratches and laps

It is suitable for carbon steel pipes, structural tubes, and precision ERW pipes.


Position in ERW Tube Mill

In an ERW Tube Mill, the eddy current testing machine is installed:

  • After HF welding

  • After cooling section

  • Before or after the sizing machine

This position allows real-time monitoring of weld quality and helps prevent defective pipes from entering the finishing process.

  • Eddy current machine
  • Eddy Current Flaw
  • Weld Seam Eddy Current Machine

 


Жұмыс принципі

  1. 📍The probe generates a high-frequency alternating magnetic field

  2. 📍Eddy currents are induced on the pipe surface

  3. 📍Any defect causes a change in the eddy current signal

  4. 📍The system analyzes the signal and triggers alarms or markings

This method is non-contact, fast, and highly sensitive, making it ideal for continuous online inspection.


Key Features

  • Online inspection for ERW tube mills

  • High sensitivity for weld seam detection

  • Stable digital signal processing

  • Non-contact testing, no damage to pipes

  • Suitable for round, square, and rectangular tubes

  • Optional marking and alarm system

  • Easy operation and low maintenance
