ASNT

Nondestructive testing

Nondestructive testing is what turns a weld into an accepted weld. ONIX runs and interprets the tests with an ASNT-certified inspector, on its own jobs or on third-party work.

Scope

What it covers

Scope is tuned to each project. This is what ONIX normally executes within this service.

  • Ultrasonic testing (UT)

    Detection of internal discontinuities in welds and measurement of remaining wall thickness.

  • Magnetic particle testing (MT)

    Detection of surface and near-surface discontinuities in ferromagnetic materials.

  • Liquid penetrant testing (PT)

    Detection of surface-breaking discontinuities in any non-porous material.

  • Radiography (RT) and visual testing (VT)

    Radiographic records of joints, plus dimensional and weld-profile visual inspection.

Deliverables

What stays
on paper.

The steel is handed over erected and the dossier is handed over in your hand. This is what it contains for this service.

Frequently asked questions

Can I contract interpretation without the testing?

Yes. We interpret the tests and issue the signed report online, over records taken by another team.

Which test does my job need?

It depends on the applicable code, the material and the joint type. It is defined once the project specification is reviewed.

Who signs the results?

An ASNT-certified inspector. That signature is what turns the test into a document you can put in front of a client or an auditor.

What do you need to quote testing?

The number and type of joints, material and thickness, the applicable code and the job location.

How soon is the report delivered?

Turnaround is agreed with the scope: per-joint reports are delivered as testing progresses, and the consolidated report at close-out.
