Описание (английский):

This document specifies a method for determining the capability of a manufacturer to use the friction stir welding (FSW) process for the production of products of the specified quality. It specifies quality requirements, but does not assign those requirements to any specific product group. In this document, the term "aluminium" refers to aluminium and its alloys. This document does not apply to friction stir spot welding which is covered by the ISO 18785 series.

Overview

SIST EN ISO 25239-5:2020 establishes quality and inspection requirements for friction stir welding (FSW) of aluminium and its alloys. Published by SIST in 2020 and identical to EN ISO 25239-5:2020, this international standard provides manufacturers with a structured approach to confirm their capability to produce welded aluminium components of specified quality using FSW. It defines general quality requirements applicable across industries and does not assign requirements to a particular product group. The standard applies to FSW of aluminium but specifically excludes friction stir spot welding, which is covered by the ISO 18785 series.

Key Topics

Qualification of Personnel

Specifies that welding operators must be qualified in accordance with ISO 25239-3.
Inspection and testing personnel should be suitably competent and preferably qualified according to ISO 9712 or equivalent.

Equipment Requirements

Emphasizes the use of suitable, well-maintained FSW equipment capable of producing welds that meet acceptance criteria.
Requires reproducibility testing after equipment installation, repair, or relocation to ensure consistent weld quality.

Welding Procedure Specifications (WPS)

Production welding must follow a qualified Welding Procedure Specification.
Manufacturers are responsible for ensuring correct use and traceability of the WPS.

Pre-weld and Post-weld Activities

Includes guidelines for joint preparation, pre-weld cleaning, and temperature control.
If needed, postweld heat treatments must be documented and compatible with component specification.

Inspection and Testing

Covers inspection and testing at several stages: before, during, and after welding.
Details non-destructive and destructive testing methods including visual, penetrant, radiographic, ultrasonic, tensile, bend, hardness, and fracture tests.
Provides acceptance criteria for weld imperfections, referencing ISO 6520-1 and others as appropriate.
Addresses correction of non-conforming weld geometries and repair protocols.

Identification and Traceability

Continual identification and traceability of the welds, WPS, and operators throughout the production process is required.

Applications

Manufacturing of Aluminium Structures

Supports quality assurance in the FSW of parts for sectors such as transportation (railcar bodies, ship hulls), aerospace, construction, and consumer products.
Relevant for serial production as well as custom manufacturing where FSW is used for joining aluminium alloys.

Quality Management Systems

Provides a framework for welding quality management systems to demonstrate compliance in audits and certifications.
Helps manufacturers meet customer and regulatory requirements for welded aluminium assemblies.

Process Improvement and Training

Encourages best practices in FSW operations, from equipment maintenance to documentation and inspection.
Supports the training and qualification of welding and inspection staff, crucial for maintaining high production standards.
