Spark Erosion Technology 2025

Spark Erosion Technology

Spark erosion, also known as Electrical Discharge Machining (EDM), is a precision, non-contact metal removal method used primarily to remove damaged or seized metallic components. Petrotec provides spark erosion as part of its field service capabilities for equipment where traditional mechanical removal is not feasible.

Key Benefits

  • Matches proven standards

    Used by leaders like NOMAC for turbine blade and valve seat repair.

  • Fully compliant with QHSE requirements including JSA, Method Statements, and ITPs

    Spark erosion services integrated with Petrotec’s mechanical service portfolio.

  • Expert Execution by Trained Technicians

    Execution by trained technicians as part of broader maintenance scopes.

  • Full QHSE Compliance

    Fully compliant with QHSE requirements including JSA, Method Statements, and ITPs.

  • High Precision and Accuracy

    Ensuring tight tolerances and complex geometries that are difficult to achieve with conventional machining.

  • Non-contact precision

    Suitable for fragile or thin-walled materials.

  • No Heat-Affected Zone (HAZ)

    No thermal distortion or metallurgical damage.

  • Preserves component integrity

    enabling reuse or recertification post-repair.
