What is ISO 2553:2019 Welding and allied processes – Symbolic representation on drawings – Welded joints?
ISO 2553:2019 is an international standard that specifies the rules for the symbolic representation of welded joints on technical drawings. It is applicable to welding, brazing, and soldering processes, and provides a standardized method for representing welded joints in engineering drawings. The standard includes the following elements:
Basic weld symbols: These symbols represent the geometry of the welded joint, including the type of joint, the position of the weld, and the size of the weld.
Supplementary symbols: These symbols provide additional information about the welding process, such as the type of welding process, the welding current, and the welding position.
Resistance welding symbols: These symbols are used to represent resistance welding processes, including spot, seam, and projection welding.
Brazing and soldering symbols: These symbols are used to represent brazing and soldering processes, including the type of joint, the size of the joint, and the filler metal used.
The purpose of ISO 2553 is to provide a standardized method for representing welded joints on technical drawings. So, By using a common set of symbols, engineers and designers can communicate information about welded joints in a clear and consistent manner.
This can help to improve the quality and accuracy of engineering drawings, and reduce the risk of errors or misunderstandings in the welding process.
Requirements of this BS EN ISO 2553:2019
Weld symbols: The standard specifies a set of basic weld symbols that represent the geometry of the welded joint. Including the type of joint, the position of the weld, and the size of the weld. The symbols must be drawn in accordance with the standard and placed on the appropriate part of the drawing.
Supplementary symbols: The standard provides a set of supplementary symbols that provide additional information about the welding process. Such as the type of welding process, the welding current, and the welding position. So, These symbols must be used in accordance with the standard and placed on the appropriate part of the drawing.
Size and location: The symbols must be drawn to the appropriate size and located in the correct position on the drawing. The standard specifies the size and location requirements for the symbols.
Clear and concise: The symbols must be clear and concise, and must accurately represent the geometry of the welded joint. So, the standard provides guidelines for drawing the symbols to ensure clarity and accuracy.
Compliance: Compliance with ISO 2553 is mandatory for technical drawings that include welded joints. Thus, this ensures that all engineering drawings that include welded joints are standardized and consistent.
Overall, ISO 2553 provides a set of requirements for the symbolic representation of welded joints on technical drawings. These requirements help to ensure that the symbols are clear, concise, and accurately represent the geometry of the welded joint. So, Compliance with the standard is mandatory to ensure that all engineering drawings that include welded joints are standardized and consistent.
