TS EN ISO 4063

TS EN ISO 4063 is a standard on the nomenclature of welding and allied processes and the use of reference numbers. It focuses on the terminology used to identify different joining and surfacing processes through a common coding system. Although this edition has been withdrawn, the subject remains important for clear technical communication in manufacturing engineering.

What process nomenclature and reference numbers do

In welding practice, many different processes can serve similar production needs: arc welding, resistance welding, gas-shielded methods, laser or electron-beam processes, and others. A structured classification helps distinguish these methods by their energy source, shielding, material interaction, and mode of application. Reference numbers make it easier for drawings, procedures, production plans, and quality records to point to the same process without ambiguity.

Why this matters in welding technology

In general technical use, nomenclature standards reduce confusion, support process selection, and create a shared language across companies and industries. “Welding and allied processes” is a broader family than simple fusion joining alone and can include related joining, surfacing, cutting, or brazing-type processes depending on context. A consistent naming system helps engineers, technicians, and document users distinguish between closely related methods and avoid misunderstandings caused by local naming habits.

• The standard’s focus is process naming and reference numbering.
• Its title points to the technical classification of welding and related joining or surfacing processes.
• Such standards support consistent terminology in drawings and manufacturing documents.
• Even though this edition was withdrawn, the topic remains foundational in welding engineering terminology.
