  • Visual testing (ISO 17637)
  • Acceptance criteria (ISO 5817 / ISO 10042)
  • NDT coordination (PT/MT/UT/RT)

International Welding
Inspector

Independent and objective verification of your welds. Our IWI-certified inspectors (IWI-B/S/C) assess joints against the applicable standards, coordinate NDT, and deliver clear reports that fit seamlessly into your QA/QC and ISO 3834 system.

What we inspect

  • Visual & dimensional checks (VT)
    Weld prep and fit-up, root & cap, bead profile, undercut, reinforcement, alignment, and overall workmanship
  • Compliance & acceptance
    Verification against acceptance criteria (e.g., ISO 5817 / ISO 10042) and WPS compliance on parameters, positions, backing/purging, interpass
  • Materials & consumables
    Material ID/heat numbers, certificates (EN 10204), filler metals, shielding gases, and handling/storage
  • Surface condition & post-weld
    Cleanliness, discoloration on stainless, grinding/finishing, pickling & passivation where required

NDT coordination

  • Method & extent
    PT, MT, UT, RT selection and test scope based on risk, thickness, and access
  • Sequencing & witnessing
    Preparation of surfaces, timing versus production steps, witnessing critical holds
  • Evaluation & reporting
    Interpretation of indications against the specified class; clear documentation and release recommendations

Documentation & traceability

  • Inspection & Test Plan (ITP), weld maps, punch lists
  • Photo reports and dimensional records
  • Complete dossier: WPS/WPQR references, certificates, NDT reports, and final release

Standards & guidelines

  • ISO 17637 (visual testing) and ISO 17635 (general rules for NDT of welds)
  • ISO 5817 / ISO 10042 (acceptance criteria)
  • ISO 3834 (quality requirements for fusion welding)

Outcomes

  • Demonstrable quality
    Objective evidence that welds meet the specified class
  • Fewer surprises
    Earlier detection of deviations and targeted corrective actions
  • Clean handover
    Complete, audit-ready documentation

When to involve us

  • Before start-up
    Define ITP and acceptance class per joint type
  • During production
    Fit-up checks, in-process VT, NDT coordination
  • Pre-delivery
    Final VT/dimensional, dossier check, and release

Industries & applications

Stainless and carbon steel pipework (food/pharma), machine & equipment fabrication, frames and structures, skids and modules—prototypes through series production and site installations.
