This International Standard defines the rules to be applied for symbolic representation of welded, brazed and soldered joints in metallic materials on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. This International standard is a combined specification that recognizes that there are two different approaches in the global market to designate the arrow side and other side on drawings. It should be noted that: - Clauses, Tables and Figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on the dual reference line from ISO 2553:1992; - Clauses, Tables and Figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on the single reference line from AWS A2.4; - Clauses, Tables and Figures which do not have the suffix letter "A" or the suffix letter "B" are applicable to both systems. Systems A and B should not be mixed and drawings shall clearly indicate which system is used as well as units of measurement in accordance with ISO 129-1. The symbols shown in this International Standard can be combined with other symbols used on technical drawings for example to show surface finish requirements. Clause 7 describes an alternative designation method which can be used to represent welded joints on drawings by specifying essential design information, e.g. 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.
