International Welding
Technologist

As an IWT (International Welding Technologist) we bridge engineering and the shop floor. We translate requirements into executable procedures, safeguard qualifications, and make your welding system perform predictably—from design and prototype to series production and final handover.

What does an IWT welding coordinator do?

We take the lead on welding technology so quality, lead time, and costs stay in balance.

  • Procedures & qualifications
    Draft/maintain WPS, guide WPQR, verify welder qualifications
  • Material & process selection
    Material pairings, filler metals, shielding gases, heat input/interpass
  • Production support
    Fit-up, back purging, distortion control, and on-floor troubleshooting
  • Documentation & traceability
    Welding dossiers, certificates, measurement reports, and release

Approach

Fast, pragmatic, and aligned with your risk class and schedule.

  1. Intake & scope
    Define requirements, standards, materials, processes, and planning
  2. Quality plan / ITP
    Inspection points, witness/hold, and acceptance classes
  3. Implementation
    Author WPS, supervise WPQR, brief operators, lock in parameters
  4. Verification & handover
    VT/NDT coordination, reporting, and final release

Standards & guidelines

We work to leading European standards and integrate with your QA/QC system.

  • ISO 14731 (welding coordination) and ISO 3834 (quality assurance)
  • EN ISO 15609/15614 (WPS/WPQR) and EN ISO 9606-1 (welder qualification)
  • EN ISO 5817 / 10042 (acceptance) and EN ISO 17637 (VT)

Outcomes for your project

  • Stable process
    Less rework and repeatable quality
  • Faster delivery
    Clear criteria and fewer discussions
  • Complete dossier
    WPS/WPQR, certificates, and inspection reports in order
