标准摘要
[中文适用范围]： 本文件建立了以下术语： ——焊接； ——硬钎焊、锡焊和钎焊； ——热切割；每个过程都由参考号标识。 它涵盖了主要流程（一位数）、组（两位数）和子组（三位数）。 任何流程的参考号最多为三位数。 该系统旨在帮助计算机化和起草图纸、工作文件和焊接工艺规范，并实现工艺的统一国际指定。 本文档并未涵盖所有流程变体。 对于未列出的变体，可以用附加信息来补充过程编号。 [外文原描述]： This document establishes a nomenclature for: — welding; — brazing, soldering and weld brazing; — thermal cutting; with each process identified by a reference number. It covers the main processes (one digit), groups (two digits) and sub-groups (three digits). The reference number for any process has a maximum of three digits. This system is intended as an aid in computerization and the drafting of, for example, drawings, working papers and welding procedure specifications, and enables the uniform international designation of the processes. This document does not cover all process variants. The process numbers can be supplemented with additional information for variants not listed.
