TS EN ISO 25239-1

TS EN ISO 25239-1 is the vocabulary standard for friction stir welding of aluminium, establishing the core terms and concepts used in this field. Rather than setting up a welding procedure itself, this part aligns the language used by engineers, quality teams and manufacturers so that the same expressions carry the same meaning across documents and organisations.

How the terminology is organised

Friction stir welding is a solid-state joining process: instead of melting the base metal in the manner of conventional arc welding, a rotating tool generates frictional heating and mechanical stirring to form the joint. For aluminium and aluminium components, a consistent vocabulary is especially important when discussing welding knowledge, quality requirements, welding procedure specifications, procedure approval and welding personnel. The value of this standard lies in reducing ambiguity in technical specifications, procedures and training materials.

Why it matters for aluminium fabrication

Aluminium is widely used where low weight, corrosion resistance and good formability are important, including transport, aerospace, marine and general manufacturing applications. Friction stir welding is often chosen for such materials because it can support low distortion, good repeatability and suitable joint performance. As a vocabulary standard, this document helps different stakeholders describe process capability, quality management and personnel qualification in a common technical language.

This record is withdrawn, but it remains useful as a terminology reference for understanding friction stir welding of aluminium and interpreting related technical documentation.
