EDM notches in all shapes and forms

All electrically conductive materials allow EDM-ing of EDM notches:

  • Steel, iron and stainless steel;
  • Nickel alloys;
  • Aluminium and aluminum alloys;
  • Titanium, zirconium, tantalum;
  • and many more…

Any shape is possible: straight, angled, concave of convex. Blind or through. Either in sheet metal, pipes, tubes, rings, gears or custom parts. Wire-edm, die sinking edm and small hole edm’ing are all techniques that are available. Depending on the shape and accuracy of the edm notches EDMnotch.com always chooses the cheapest appropriate machining method.

Non-destructive testing

The custom calibration blocks we EDM are used for non-destructive testing by various methods:

  • Eddy Current Testing (ET)
  • Ultrasonic Testing (UT) in various ways such as:
    • Time-of-flight diffraction (TOFD)
    • Phased Array (PA)
  • Advanced Ultrasonic Testing (A-UT)

Weld inspection

For weld inspection we EDM small notches into custom calibration blocks. Our clients weld those blocks before shipment to our workshop. Clients use various methods for welding: SMAW, SAW, GMAW, FCAW to name a few. The indications can be machined in longitudal, transversal or any other direction – according to your specifications.
