About
De Weerd Welding Services

De Weerd Welding Services is a practical welding partner that unites IWT (International Welding Technologist), IWI (International Welding Inspector) and certified TIG welding under one roof. We help manufacturers and machine builders achieve predictable, compliant results—from the first idea to final handover—with clear procedures, tight execution and audit-ready documentation.

What we do

We translate standards and customer requirements into solutions that work on the shop floor. Typical work includes hygienic stainless process piping, precision frames and skids, aluminium housings, and independent welding inspections. Whether in our workshop or on site, we combine coordination, execution and verification so your welding process runs smoothly.

How we add value

  • One team, three roles
    IWT for procedures and optimisation, IWI for verification, TIG for precise execution
  • First-time-right
    Fewer deviations and rework through clear WPS/WPQR, parameter control and fit-up checks
  • Proof of quality
    Transparent reporting, weld maps and certificates that pass audits without fuss

Way of working

  1. Intake & scoping
    Materials, joint types, acceptance class, planning
  2. Plan & prepare
    WPS/WPQR, ITP with hold/witness points, welder qualifications
  3. Execute & support
    Controlled TIG welding, back purging where required, in-process VT
  4. Verify & hand over
    VT/NDT coordination, photo/measurement records, release report

Standards & compliance

We work within recognised European frameworks and align with your QA/QC system.

  • ISO 14731 (welding coordination) and ISO 3834 (quality requirements)
  • EN ISO 15609/15614 (WPS/WPQR) and EN ISO 9606-1 (welder qualification)
  • ISO 17637 (visual testing), ISO 17635 (general rules), ISO 5817 / ISO 10042 (acceptance)
