Crack Detection
Crack detection targets selected locations where fatigue, loading, repair history or visible evidence raises concern. It uses a method matched to the material and likely crack orientation.
Overview
Crack detection targets selected locations where fatigue, loading, repair history or visible evidence raises concern. It uses a method matched to the material and likely crack orientation.
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
Accessible weld toes, shafts, pins, lifting attachments and machinery frames may require different surface or internal examination arrangements.
Methods & Limitations
MPI, PT and ECT investigate appropriate surface indications; UT can address some internal-flaw or sizing questions. A specialist chooses complementary techniques where one method cannot provide sufficient coverage.
Small size, unfavourable orientation, tight closure, coatings and inaccessible faces can limit detection. No negative result proves that an entire asset is crack-free or predicts future fatigue behaviour.
Typical Defects & Conditions
- Suspected fatigue cracking at stress concentrations
- Crack-like indications at repairs and welded attachments
- Changes at previously documented indication locations
Planning the Inspection
Share operating duty, incidents and previous repairs, and preserve suspect surfaces until preparation is agreed. Identify who will decide on isolation, repair or further assessment when a finding is reported.
Expected Reporting Deliverables
Located findings, method sensitivity basis, examined extent and photographs support review. Sizing is stated only where the technique supports it, with unexamined regions and recommended confirmation identified.

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.
