APPLICATION 63 · CONSTRUCTION & INFRASTRUCTURE

Welded connections and bolted assemblies

Verification of joint preparation, welding quality, bolt installation and completed connections against approved specifications. Within industrial construction and civil-mechanical installation projects from fabrication through handover, this asset can directly influence quality assurance, structural adequacy, installation conformity and reliable commissioning. A focused integrity programme should therefore connect the design basis, materials, service history, previous findings and current operating condition, so that inspection effort is directed to credible damage locations and produces information that supports practical maintenance decisions.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • Material or traceability discrepancies, dimensional nonconformance and manufacturing defects.
  • Weld discontinuities, heat-treatment or hardness concerns, repair quality and incomplete process records.
  • Damage introduced during forming, machining, assembly, testing, preservation or handling.

How IAIS UAE may support

  • Prepare inspection and test surveillance around approved drawings, specifications, ITP hold points and acceptance criteria.
  • Verify materials, traceability, fit-up, welding, NDT, dimensions, heat treatment, pressure testing and documentation as applicable.
  • Raise and close observations or nonconformities and confirm the release dossier reflects the accepted manufacturing status.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Inspection release notes, surveillance reports, NDT and dimensional records, traceability review, punch list and final dossier status.

Codes & standards

The activity may be planned and reported against the applicable provisions of AWS D1.1, ISO 17635, ISO 9712, EN 1090, ASTM, BS, project specifications and authority requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
