Ultrasonic Testing

Conventional ultrasonic testing sends sound into a component and interprets returning signals to investigate internal reflectors or measure thickness. It can add volumetric information that a surface examination cannot provide.

Overview

Conventional ultrasonic testing sends sound into a component and interprets returning signals to investigate internal reflectors or measure thickness. It can add volumetric information that a surface examination cannot provide.

NDT Australia provides a single enquiry and co-ordination point for industrial inspection through specialist partners. The proposed provider, personnel competence, method-specific qualifications where required, insurance and any separate approval requirements are checked for the actual scope before appointment; no general accreditation or acceptance guarantee is implied.

Assets & Materials

Suitable welds, plates, structural sections, pressure components and pipework need a sound path and surface compatible with the chosen probe and procedure.

Methods & Limitations

Pulse-echo examination uses a calibrated instrument, probe and reference arrangement appropriate to the material and geometry. Weld flaw examination and straight-beam thickness measurement are different scopes and should be specified separately.

Coupling, coarse-grained material, attenuation, near-surface zones and reflector orientation can restrict coverage. Complex joints may not be fully examinable with conventional UT. PAUT and TOFD are not assumed to be available as standalone offerings.

Typical Defects & Conditions

  • Internal weld reflectors such as suspected lack of fusion
  • Laminations in suitable plate geometry
  • Remaining thickness at identified measurement locations

Planning the Inspection

Supply weld preparation drawings, nominal thickness, material and accessible scanning faces. Agree the acceptance specification and whether the objective is flaw detection, sizing or thickness trending.

Expected Reporting Deliverables

Specify weld or component identifiers, scan extent, probe and calibration basis, located indications and areas not covered. Recorded signal data and sizing detail depend on the agreed technique.

Applications

Ultrasonic Testing is applied across a wide range of assets and industries, including:

  • Suitable welds, plates, structural sections, pressure components and pipework need a sound path and surface compatible with the chosen probe and procedure.
  • Inspection planning for construction assets and operators
  • Inspection planning for manufacturing assets and operators
  • Inspection planning for mining assets and operators

Standards & Competence Context

The references below are planning context, not a claim of accreditation, certified compliance or a universal acceptance rule. Confirm the applicable edition, part, material, procedure and acceptance criteria for this asset. Verify the appointed personnel's method, level and sector competence, insurance and any engineering authority required for the scope before work. A method standard is not itself a return-to-service approval.

  • AS 2207 — Non-destructive testing of welds by ultrasonics
  • ISO 16810 — Ultrasonic testing general principles

Why Choose NDT Australia

  • One enquiry point for scope and specialist-partner co-ordination
  • Asset-linked findings with examination extent and limitations
  • Separate identification of engineering and operational decisions

Frequently Asked Questions

No. They use different probe and acquisition arrangements. This page covers conventional UT; a separate phased array scope requires confirmation of provider capability, procedure and reporting before it can be offered.
