What is EN ISO 15609-2:2019?

EN ISO 15609-2:2019 is an international standard that provides guidelines for the specification and qualification of welding procedures for metallic materials. This standard is part of a series of standards developed by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN).

The Importance of EN ISO 15609-2:2019

EN ISO 15609-2:2019 plays a crucial role in ensuring the quality and safety of welded products. It establishes requirements for the selection, preparation, and qualification of welding procedures, helping to ensure that welds meet the required strength, integrity, and performance criteria.

By following the guidelines outlined in this standard, welding professionals can determine the appropriate welding parameters, such as current, voltage, travel speed, and preheating temperature. These parameters are essential for achieving sound welds that are free from defects and capable of withstanding the intended service conditions.

Key Features of EN ISO 15609-2:2019

EN ISO 15609-2:2019 incorporates several key features to facilitate its implementation:

Definition of the necessary variables that need to be considered when specifying a welding procedure, including material type, joint design, and welding position.

Guidelines for performing qualification tests on welding procedures to demonstrate their compliance with specific codes or standards.

Classification of welding procedures based on their specific characteristics, ensuring that relevant information is available to users.

Requirements for documentation, including the preparation of a Welding Procedure Specification (WPS), which details the welding parameters and precautions to be followed.

Conclusion

EN ISO 15609-2:2019 is an essential standard for the welding industry. By adhering to its guidelines, welding professionals can ensure the quality and reliability of their welds, ultimately leading to safer and more durable products. It provides a systematic approach to welding procedure qualification and helps maintain consistency and uniformity in the welding process.
