标准摘要
[中文适用范围]： 本文件定义了技术图纸上焊接接头符号表示所应用的规则。 这可以包括有关焊缝的几何形状、制造、质量和测试的信息。 本文件的原理也适用于钎焊和钎焊接头。 人们认识到，全球市场上有两种不同的方法来指定图纸上的箭头侧和另一侧。 本文件中： ——带有后缀字母“A”的条款、表格和图形仅适用于基于双参考线的符号表示系统； ——带有后缀字母“B”的条款、表格和图形仅适用于基于单一参考线的符号表示系统； ——没有后缀字母“A”或“B”的条款、表格和图形适用于两个系统。 本文件中显示的符号可以与技术图纸上使用的其他符号结合使用，例如显示表面光洁度要求。 提出了一种替代指定方法，该方法可用于通过指定基本设计信息（例如焊接尺寸、质量水平等）在图纸上表示焊接接头。 然后由生产单位确定接头准备和焊接工艺，以便满足规定的要求。 注：本文件中给出的示例（包括尺寸）仅用于说明目的，旨在证明原理的正确应用。 [外文原描述]： This document defines the rules to be applied for symbolic representation of welded joints on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. The principles of this document can also be applied to soldered and brazed joints. It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In this document: — clauses, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; — clauses, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; — clauses, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems. The symbols shown in this document can be combined with other symbols used on technical drawings, for example to show surface finish requirements. An alternative designation method is presented which can be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements. NOTE Examples given in this document, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles.
