What is EN ISO 15614-2:2019?

EN ISO 15614-2:2019 is a technical specification published by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO). It provides guidelines for the qualification of welding procedures for metallic materials. This standard is part of a series of standards that help ensure the quality and safety of welded products.

Understanding the Scope

This standard applies to fusion welding procedures for metallic materials, including steel, aluminum, and nickel alloys. It covers various types of welding processes, such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and submerged arc welding (SAW). The purpose of this standard is to establish a framework for evaluating the compatibility of welding procedures with specific welding conditions.

The Qualification Process

To qualify a welding procedure according to EN ISO 15614-2:2019, several steps must be followed. First, the responsible party must define the essential variables, which include parameters such as base material type, thickness, welding process, and welding position. Then, a suitable test weld must be performed, following the specified welding procedure.

The test weld is examined and evaluated based on defined acceptance criteria, which assess the mechanical properties, soundness, and microstructure of the welded joint. If the test weld meets these criteria, the welding procedure is considered qualified for the given set of variables.

Importance of Compliance

Compliance with EN ISO 15614-2:2019 is crucial for various reasons. Firstly, it ensures that welding procedures are properly qualified, minimizing the risk of defects or failures in welded products. Secondly, compliance allows for easier transferability of welding procedures between different organizations and projects, promoting efficiency and standardization in the welding industry.

Additionally, adherence to this standard demonstrates a commitment to quality and safety, which can enhance an organization's reputation and competitiveness. Ultimately, compliance with EN ISO 15614-2:2019 helps ensure that welded products meet the required performance and durability expectations.

Overall, EN ISO 15614-2:2019 is an essential technical specification for those involved in welding procedures and practices. It provides clear guidelines on how to qualify welding procedures and ensures that they meet the necessary quality and safety standards. By following this standard, organizations can achieve consistency, efficiency, and reliability in their welding processes.
