TS EN ISO 17659

TS EN ISO 17659 is a multilingual terminology standard for welded joints, presented with illustrations. It focuses on the most common terms used for joint types, joint preparation and welds, giving their equivalents in English, French and German. As such, it provides a shared technical vocabulary that helps align welding design language, fabrication practice and drawing interpretation.

What the illustrated terms are meant to clarify

Rather than simply listing words, the standard links terminology to pictorial representations of typical joint features. In welding, the distinction between joint geometry, edge preparation and weld form matters because similar-looking terms can refer to different configurations or manufacturing intentions. The figures are schematic aids intended to show characteristic features, not necessarily the exact way those items must appear on design or technical drawings. In general technical use, this makes the standard a terminology reference rather than a fabrication rulebook.

Why multilingual terminology matters in welding work

• It aligns common joint, preparation and weld terms across English, French and German.
• It helps reduce ambiguity when reading specifications, manuals and engineering drawings.
• It supports training and international communication in welding-related work.
• It presents the official ISO-language terms together with the German equivalents published under DIN responsibility.

In practical terms, a standard like this is useful wherever welding language must be consistent across teams, countries or documentation systems. TS EN ISO 17659 should be understood as a terminology and illustration reference for welded joints, not as a standard that defines an individual welding process or a clause-by-clause production method.
