Full title and description

BS EN ISO 3834-2:2021 — Quality requirements for fusion welding of metallic materials — Part 2: Comprehensive quality requirements. This publication specifies the comprehensive welding quality requirements and acceptance criteria for manufacturers and organisations whose products include fusion welding of metallic materials, and it is published as a British (BS EN) adoption of the ISO 3834-2:2021 international standard.

Abstract

This standard defines comprehensive quality requirements for fusion welding of metallic materials in both workshop and site conditions. It covers the organisational arrangements, qualification and responsibilities of personnel, welding procedures, inspection and testing, documentation and traceability needed to achieve and demonstrate weld quality suitable for safety- and performance-critical applications.

General information

• Status: Published.
• Publication date: April 2021 (ISO edition published 2021-04).
• Publisher: International Organization for Standardization (ISO); published/adopted in the UK catalogue as BS EN ISO 3834-2:2021 (British Standards Institution for the BS EN adoption).
• ICS / categories: 25.160.01 (Welding).
• Edition / version: Edition 3 (2021).
• Number of pages: 11 pages (ISO published text length).

Scope

The standard specifies comprehensive requirements for a welding quality management system to ensure the production of welded components that meet specified technical and safety requirements. It applies to fusion welding of metallic materials performed in workshops and at field installation sites and is intended to be used where high integrity and traceability of welds are required (for example structural steelwork, pressure equipment, transport and heavy fabrication). It replaces the earlier 2005 edition for the comprehensive-level requirements.

Key topics and requirements

• Definition and implementation of a welding quality management system appropriate to the comprehensive (highest) level of ISO 3834.
• Responsibilities and competence requirements for welding personnel, including welding coordinators and qualified welders.
• Welding procedure specification (WPS) and welding procedure qualification records (WPQR) requirements.
• Inspection, non-destructive testing (NDT) and acceptance criteria for welds, including sampling, testing frequency and reporting.
• Material and process traceability, documentation control and records retention.
• Handling of nonconformities, corrective actions and continuous improvement measures.
• Requirements for subcontracting, supplier control and verification activities related to welding operations.

Typical use and users

Used by fabricators, manufacturers, contractors and organisations involved in structural steelwork, pressure equipment, piping, shipbuilding, heavy engineering and construction where weld integrity is critical. Typical users include quality managers, welding coordinators, production managers, certification bodies, inspectors and design engineers seeking to specify or verify welding quality at the comprehensive level.

FAQ

Q: What is this standard?

A: BS EN ISO 3834-2:2021 is the British-adopted form of ISO 3834-2:2021, the international standard that specifies comprehensive quality requirements for fusion welding of metallic materials.

Q: What does it cover?

A: It covers the organisation, responsibilities, personnel competence, welding procedures, inspection and testing, documentation and traceability necessary to manage and demonstrate high-integrity fusion welding processes in both workshops and field installations.

Q: Who typically uses it?

A: Fabricators, contractors, QA/QC managers, welding coordinators, inspectors and certification bodies in industries such as structural steelwork, pressure equipment, shipbuilding, transport and heavy engineering.

Q: Is it current or superseded?

A: The 2021 edition (Edition 3) is the current published version and supersedes ISO 3834-2:2005. Organisations should reference the 2021 text for current comprehensive-level requirements.

Q: Is it part of a series?

A: Yes — ISO 3834 is a series of parts that define different levels of welding quality requirements (parts 2, 3 and 4 for comprehensive, standard and elementary requirements respectively), plus related guidance and normative references.
