EDM notches in all shapes and forms

EDM notches can be machined in any electrically conductive material:

  • 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. EDM notches can be made by wire-edm, sinker edm and small hole edm’ing. Depending on the shape and accuracy of the edm notches we always choose 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 notches into custom calibration blocks that are welded by our clients. Welding can be done by various methods: SMAW, SAW, GMAW, FCAW to name a few. The indications can be machined in longitudal, transversal or any other direction – according to your specifications. Read more about custom calibration blocks.
