Overview

EN 2574:1990 is a European standard developed by the CEN (European Committee for Standardization) that focuses on the aerospace industry's welding practices. Specifically, it details the information to be shown on drawings or other technical documents relating to welding of metallic materials used in aerospace manufacturing. Accurate representation of welds on engineering drawings is critical to ensure quality, consistency, and safety in aerospace structures.

This standard provides essential guidelines for the indication and notation of welds, supporting clear communication between design, manufacturing, and quality assurance teams within aerospace projects.

Key Topics

• Welding Indications on Drawings
  Specifies the symbols, annotations, and supplementary details required to convey weld types, sizes, positions, and quality standards directly on engineering and assembly drawings.

• Metallic Materials Focus
  Applies specifically to the welding of metallic materials commonly used in aerospace components, ensuring material compatibility and strength requirements are clearly documented.

• Standardized Symbols and Notations
  Defines a consistent system of symbols to avoid ambiguity in weld representation, enhancing interoperability and clarity across different teams and contractors.

• Integration with Aerospace Manufacturing Processes
  Supports the aerospace sector's high-precision demands by providing standardized information that aligns with industry fabrication and inspection workflows.

Applications

• Aerospace Engineering and Design
  Engineers and designers use EN 2574 to create detailed welding instructions on technical drawings to guarantee that welds meet design and safety requirements.

• Manufacturing and Fabrication
  Welding personnel refer to standardized drawing information to execute welds precisely as specified, ensuring structural integrity.

• Quality Control and Inspection
  Inspectors verify welded assemblies against the documented weld information, ensuring conformity with aerospace safety and reliability standards.

• Supply Chain Communication
  Facilitates clear communication between OEMs, subcontractors, and suppliers by providing uniform welding documentation standards.

• AWS A2.4 – American Welding Society – Standard Symbols for Welding, Brazing, and Nondestructive Examination (widely used reference)

Practical Value

Implementing EN 2574:1990 enables aerospace companies to:

• Achieve uniformity and clarity in welding documentation, reducing errors and rework
• Enhance communication efficiency between engineering, production, and inspection teams
• Promote compliance with aerospace quality and safety requirements
• Facilitate international collaboration by adopting a recognized European standard

Adopting EN 2574:1990 supports best practices in documenting welds on aerospace drawings, contributing to safer, high-quality aircraft and spacecraft manufacturing processes.
