ISO 2553:2013定义了技术图纸上焊接接头符号表示的规则。这可能包括焊缝的几何形状、制造、质量和测试信息。本标准的原则也适用于焊接和钎焊接头。众所周知，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。在ISO 2553:2013中:带有后缀字母“A”的章节、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”的章节、表格和图形仅适用于基于单个参考线的符号表示系统；没有后缀字母“A”或“B”的章节、表格和图表适用于这两种系统。所示符号可与技术图纸上使用的其他符号组合，例如用于显示表面光洁度要求。提出了一种替代命名方法，可用于通过指定基本设计信息（如焊缝尺寸、质量等级等）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，以满足规定的要求。

ISO 2553:2013 defines the rules to be applied for symbolic representation of welded joints on technical drawings. This may include information about the geometry, manufacture, quality and testing of the welds. The principles of this standard may 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 ISO 2553:2013: sections, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; sections, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; sections, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.The symbols shown may be combined with other symbols used on technical drawings, for example to show surface finish requirements.An alternative designation method is presented which may 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.
