Non-Destructive Testing (NDT)
Safety-critical forgings must be proven sound without being cut open. Our NDT capability covers ultrasonic examination for internal discontinuities, magnetic particle and dye penetrant inspection for surface and near-surface defects, and full hardness mapping.

Non-Destructive Testing (NDT) at a glance
Quotable facts from Avadh Techno Forge, Gundasara, Gondal, Rajkot.
- Ultrasonic Standard: ASTM A388 / customer class
- Surface Methods: MPI (wet & dry), dye penetrant
- Hardness Survey: Multi-point Brinell / Rockwell
- Reporting: Certified test report per batch
- Applicable Materials: Carbon, alloy, stainless
- Third-Party Witness: Accepted on request
Ultrasonic Testing to ASTM A388
Straight-beam and angle-beam scanning detects internal laps, bursts and inclusions that no visual check would reveal. Acceptance is judged against the customer's specified class, and the scan plan, calibration block and operator certification are all recorded.
- Straight and angle beam scanning
- Calibration against reference blocks
- Acceptance to ASTM or customer class
- Documented scan reports
Surface Inspection: MPI and DP
Magnetic particle inspection reveals cracks on ferromagnetic parts, including tight fatigue cracks invisible to the eye. Dye penetrant covers stainless and non-magnetic components. Both are applied after final machining, when a crack that matters is most likely to be exposed.
Where NDT Is Non-Negotiable
Lifting components, pressure-retaining valve and flange bodies, rail and automotive safety parts, and any forging feeding an application where failure risks life. For these we treat NDT as a release gate, not an optional extra.
People also ask
Do you allow third-party inspectors to witness NDT?
Yes, TPI agencies and customer inspectors are welcome at our Gondal works by prior appointment.
What NDT standard do you work to?
ASTM A388 for ultrasonic examination, with acceptance criteria taken from your specification since A388 defines method rather than acceptance.

Questions Answered
Do you allow third-party inspection?
+
Yes. TPI agencies and customer inspectors are welcome to witness testing at our plant by prior appointment.
Is NDT charged separately?
+
It is quoted as a line item because scope varies — 100% inspection, sampling plan or first-article only, according to what your specification demands.
Can you test parts forged elsewhere?
+
Yes, NDT job work on external forgings and castings is accepted with a written scope.
What documentation is provided?
+
A signed test report per batch stating method, equipment, calibration reference, acceptance class and result, cross-referenced to the heat number.
