Eddy Current Testing

When coatings or paint protect your equipment, traditional testing methods can be time-consuming and costly because they require stripping surfaces first. But ignoring hidden cracks or flaws under those coatings can lead to unexpected failures, safety risks, and non-compliance.

That’s where Eddy Current Testing (ET) offers the solution.

How it Works :

Using electromagnetic fields, ET induces small “eddy currents” in the conductive material. Any irregularities—such as cracks, corrosion, or changes in thickness—disrupt these currents. Our instruments instantly detect and visualize these disruptions, giving you accurate results without damaging or stripping coatings.

Advantages of ET

• ✅ No need to remove coatings or paint

• ✅ Detects both surface and subsurface defects

• ✅ Clean, chemical-free, and fast method

Limitations to Consider

• ❌ Only works on conductive materials (e.g., metals)

• ❌ Accuracy can be influenced by geometry and surface condition

• ❌ Requires skilled operators and advanced instruments

Why Choose HTT for ET?

At HTT, our certified inspectors use advanced Eddy Current equipment to give you fast, reliable results without the downtime of surface preparation. You’ll receive a clear approval or rejection report so you can take action immediately and keep your operations safe and compliant.
