Weld Inspection
Weld inspection examines nominated joints against the project requirements using visual examination and suitable complementary NDT. The result describes examined welds, not every joint in an assembly.
Overview
Weld inspection examines nominated joints against the project requirements using visual examination and suitable complementary NDT. The result describes examined welds, not every joint in an assembly.
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
Structural fabrications, pressure components, pipe spools and repair welds need traceable weld identifiers, material details and the relevant design or fabrication specification.
Methods & Limitations
VT documents accessible profile; UT may investigate internal reflectors, MPI suits ferromagnetic surfaces and PT suits clean non-porous surfaces. Method selection and sampling extent are agreed for each weld category.
Geometry, backing, coatings and access can restrict examination. Indications are evaluated against nominated criteria, not a universal pass/fail rule. Procedure qualification, welder qualification and radiography are not automatically included.
Typical Defects & Conditions
- Crack-like indications at welds and heat-affected areas
- Internal reflectors where UT is suitable
- Visible undercut, profile departures and surface porosity
Planning the Inspection
Agree hold points before coating, assembly or loading conceals examination faces. Supply weld preparation details, specified examination percentages and the person responsible for accepting findings.
Expected Reporting Deliverables
A weld register or map links method, extent, result and any re-test to each examined joint. Reports identify the acceptance basis, inaccessible areas and items awaiting engineering disposition.

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.
