MT Overview

Where MT Adds Value

Magnetic particle testing is a proven method for identifying cracks, seams, laps, and other discontinuities in ferromagnetic materials. It is well suited for welds, fabricated components, castings, and in-service equipment where dependable surface inspection matters.

Weld Inspection

Evaluate weld areas for relevant indications that could affect performance, acceptance, or long-term reliability.


Component Checks

Inspect ferromagnetic parts during fabrication, maintenance, or final quality review to support fit-for-service decisions.


Field and Shop Support

Provide flexible testing support at your facility or project site to help keep inspections aligned with schedules.


Clear Reporting

Deliver organized findings and documentation that help teams understand results and move work forward efficiently.

A Practical MT Process

Our magnetic particle testing workflow is built for consistency, traceability, and efficient turnaround. We review the inspection scope, prepare the surface as needed, apply the appropriate magnetization technique, and evaluate visible indications with care.

This approach helps clients gain dependable inspection data for maintenance planning, fabrication quality, and compliance-driven verification.
