Why compare SN EN ISO 9606-1:2018 and ISO 9606-1:2012 vs ISO 9606-1:2017

The comparison between SN EN ISO 9606-1:2018 and its predecessors, ISO 9606-1:2012 and ISO 9606-1:2017, is essential for welding professionals, organizations, and regulatory bodies. Stakeholders may seek clarity on which version best meets their qualification requirements for welders, especially in compliance with international standards. Companies must ensure that their welders are qualified according to the most current standards to enhance quality, safety, and compliance with regulatory mandates. This comparison assists decision-makers in aligning their practices with the most relevant and effective standards available in the industry.

How SN EN ISO 9606-1:2018 approaches the topic

SN EN ISO 9606-1:2018 provides an updated framework for the qualification testing of welders engaged in fusion welding of steels. This standard emphasizes the importance of ensuring that welders possess the necessary skills to produce welds that meet specified quality standards. It outlines the procedures for testing, evaluating, and certifying welders, including the essential requirements for various welding processes. The 2018 version offers significant revisions, reflecting advancements in welding technology and methodology, and addresses the growing need for harmonization with European and international standards. By implementing a structured approach to welder qualification, SN EN ISO 9606-1:2018 aims to enhance overall welding quality and safety in manufacturing environments.

How ISO 9606-1:2012 vs ISO 9606-1:2017 approaches the topic

ISO 9606-1:2012 laid the groundwork for the qualification of welders, introducing essential criteria and testing methodologies for evaluating the skills needed for fusion welding. However, the 2017 revision (ISO 9606-1:2017) brought in additional clarity and adjustments based on feedback from industry stakeholders. It refined the acceptance criteria for weld quality and provided more comprehensive guidance on the testing procedures. Both versions focus on ensuring that welders are adequately qualified to meet the demands of various welding applications, but the 2017 version is more aligned with current practices and technological advancements. The updates make it a better fit for organizations looking to remain compliant with evolving industry standards.
