What is EN ISO 3690:2012

EN ISO 3690:2012 is a technical standard that provides guidelines and requirements for the use of welding symbols on drawings, specifications, and other technical documents. This standard applies to all types of welding processes, including arc welding, gas welding, resistance welding, and others.

The Purpose of EN ISO 3690:2012

The main purpose of EN ISO 3690:2012 is to ensure clear communication between designers, engineers, and welders. By using standardized welding symbols, everyone involved in the welding process can easily understand the specific requirements and instructions, which helps to prevent errors and improve the quality of welded joints.

Key Requirements and Guidelines

EN ISO 3690:2012 outlines several key requirements and guidelines for the use of welding symbols. These include:

Standardized symbols: The standard defines a set of symbols to represent various aspects of welding, such as joint type, groove geometry, welding position, and more. These symbols must be used consistently throughout the documentation.

Placement and orientation: The standard specifies the correct placement and orientation of welding symbols on drawings and other technical documents. This ensures that the symbols are easy to locate and interpret.

Information content: Each welding symbol conveys specific information about the desired weld, including details about its dimensions, size, and other relevant parameters. The standard provides guidelines on how this information should be represented.

Additional information: In addition to the basic welding symbols, the standard allows for the inclusion of supplementary symbols to provide further information, such as welding process details or specific quality requirements.

Benefits and Impact

The implementation of EN ISO 3690:2012 brings several benefits to the welding industry. Firstly, it ensures consistency and clarity in conveying welding requirements, reducing misunderstandings and mistakes during the fabrication process. Secondly, by using standardized symbols, it becomes easier for welders from different countries or backgrounds to work together effectively. Finally, the use of this standard contributes to improved product quality, as it enables better control and monitoring of the welding process.
