What is EN ISO 15614-1:2021?


EN ISO 15614-1:2021 is a globally recognized standard that provides guidelines for the qualification of welding procedures. The importance of this standard cannot be overstated, as it ensures the quality and reliability of welded products in various industries. In this article, we will explore the key aspects of EN ISO 15614-1:2021 and break down its requirements in simple terms.

Understanding EN ISO 15614-1:2021

The purpose of EN ISO 15614-1:2021 is to establish and specify the necessary requirements for welding procedure qualification. It defines the essential variables, test methods, and acceptance criteria to ensure consistent and reliable welding practices. This standard applies to both manual and mechanized welding processes across different materials, including metals and their alloys.

EN ISO 15614-1:2021 outlines the specific steps that need to be followed when qualifying welding procedures. These steps include defining the range of application, selecting suitable base materials, determining all essential variables, preparing test specimens, performing the required tests, and documenting the results. By following these steps meticulously, manufacturers can guarantee the quality of their welded products.

Benefits and Importance

Adhering to EN ISO 15614-1:2021 offers several benefits for manufacturers and consumers alike. Firstly, it ensures that welding procedures are performed consistently, minimizing variations and defects. This, in turn, leads to improved product quality and reliability. Secondly, compliance with this standard gives manufacturers a competitive edge by demonstrating their commitment to international welding best practices.

Furthermore, EN ISO 15614-1:2021 promotes safety in welding operations. By specifying the necessary tests and acceptance criteria, it helps identify potential weaknesses or issues that may compromise the structural integrity of welded components. This proactive approach to quality control not only protects workers but also enhances overall product safety.


In conclusion, EN ISO 15614-1:2021 plays a crucial role in ensuring the quality, reliability, and safety of welded products across industries. By establishing guidelines for welding procedure qualification, this standard promotes consistency, minimizes defects, and enhances competitiveness. Manufacturers must familiarize themselves with the requirements of EN ISO 15614-1:2021 to optimize their welding processes and deliver superior products.

As consumers, knowing that a manufacturer follows this standard can give us confidence in the quality and durability of the welded products we purchase. Therefore, EN ISO 15614-1:2021 acts as a benchmark for both manufacturers and consumers, highlighting the importance of standardized and regulated welding practices.
