What is ISO 25239-2 about?
ISO 25239-2 is the second part of a multi-series international standard that covers the friction stir welding of aluminium.
ISO 25239-2 specifies design requirements for friction stir weld joints. The term “aluminium” refers to aluminium and its alloys, here. It specifies terms, definitions, design requirements such as documentation, joint design as well as additional information for the design of weld joints.
Note 1: ISO 25239-2 focuses on the Friction stir welding (FSW) of aluminium because, at the time of publication of this standard, the majority of commercial applications for Friction stir welding (FSW) involved aluminium metal.
Note 2: ISO 25239-2 does not apply to friction stir spot welding which is covered by the ISO 18785 series.
Who is ISO 25239-2 for?
ISO 25239-2 on the design of weld joints is applicable to authorities dealing with:
- Railway carriages
- Food processing equipment
- Aerospace structures
- Marine vessels
- Welders and welding operators
Why should you use ISO 25239-2?
Friction Stir Welding is a solid-state joining process, many processing conditions and materials properties can affect the microstructural evolution and mechanical behaviour of the produced friction stir welded joints.
Thus, ISO 25239-2 defines design standards that could be practised for the safe design of friction stir welded joints. It helps you to ensure that welding is carried out in the most effective way and the appropriate control is exercised over all aspects of the operation. This improves the efficiency and productivity of welding operations in industrial operations.
ISO 25239-2 help you with the guidelines to manufacture friction stir welded joints of aluminium structures and products with high quality and durability. Users of ISO 25239-2 can follow the design requirements that are in compliance with global standards for friction stir weld joints, which helps you for effective, efficient, and low-cost manufacturing.
What’s changed since the last update?
BS EN ISO 25239-2:2020 supersedes BS EN ISO 25239-2:2011, which is withdrawn. In BS EN ISO 25239-2:2020 half overlap joint has been taken into consideration and Figure 2 has been improved with respect to BS EN ISO 25239-2:2011.
