ISO 3834 Quality requirements for fusion welding of metallic materials

Defines what a welding manufacturer must control to produce consistent weld quality, at three levels: comprehensive (part 2), standard (part 3) and elementary (part 4).

CodeISO 3834Issued byISOFieldWelding quality management

What it covers

  • Review of requirements and technical review, subcontracting, welding personnel and coordination, inspection personnel.
  • Equipment, welding procedures (WPS / WPQR), welder qualification, consumables, storage of parent material, post-weld heat treatment.
  • Inspection and testing, non-conformance and corrective action, calibration, identification and traceability, quality records.

Key points for fabricators

  • Choose the part that matches the contract: EN 1090-2 links EXC3/EXC4 to part 2.
  • Certification is usually done by a third-party body and is often a pre-qualification requirement for export projects.
  • Records must show which WPS and which qualified welder produced each weld where traceability is required.

How PEB Studio supports it

WPS life cycle (Draft → Approved → Withdrawn), welder qualifications with 6-month continuity, authorisation checks at each welding report and a full audit trail support the records ISO 3834 requires.
