TS EN 2574

TS EN 2574 addresses how welding-related information is to be presented on technical drawings and associated documents for the aerospace industry. It focuses on the drawing-language rules that help welding requirements be communicated consistently, clearly, and with less risk of misunderstanding.

The role of welding information on drawings

Welding is not only a joining process; it is also a critical element of manufacturing definition, inspection, and quality control. In aerospace, joint details often require high precision, traceability, and unambiguous identification, so symbols, notes, and supplementary data on a drawing become a shared technical language across design and production. This standard is concerned with that communication layer: how welding information is shown on drawings and related documents.

What the scope is centred on

• Technical drawings and similar documents used in aerospace applications
• Representations related to welding of metallic materials
• Consistency in welding indications, marking and annotation
• A presentation approach intended to reduce drawing misinterpretation

In general technical practice, welding data on drawings connects the joint type, the weld location, the required symbols and the production notes that guide manufacture. Correct interpretation of welded joints matters not only to designers but also to fabrication, inspection and documentation teams. TS EN 2574 provides a reference for organising that communication within the aerospace context and is used together with the relevant drawing standards.
