TS EN ISO 4063

TS EN ISO 4063 defines a reference-number system for naming welding, brazing, soldering and cutting processes. It provides a common technical language that makes it easier to identify the same process consistently in drawings, work instructions and welding procedure specifications.

How the process numbering is organised

The standard arranges processes at three levels: main processes, groups and sub-groups. In general technical practice, this kind of hierarchy helps place related methods together while still distinguishing one specific process from another. A reference number therefore gives a concise, internationally understandable identifier instead of relying only on local wording or abbreviations.

This is especially useful in manufacturing documentation, where welding, brazing, soldering and thermal cutting belong to the same broad family of joining and separating operations but differ in heat input, joint formation and application. The numbering system makes those distinctions easier to record and exchange across organisations and countries.

• Provides a common reference structure for main processes, two-digit groups and three-digit sub-groups.
• Supports consistent process designation in computerised systems and technical documentation.
• Does not cover every process variant; unspecified variants may be supplemented with additional information.
• Aims at uniform international designation of the processes.

In practice, the standard is primarily a classification and terminology tool rather than a method document. Its value lies in keeping process naming consistent so that the same operation can be identified clearly across different documents, workplaces and engineering systems.
