Yes and no. is the international standard. EN ISO 15614-7 is the identical European adoption of that international standard. The technical content is exactly the same; the EN version simply adds a European foreword and, in some cases, an informative Annex ZA linking the standard to EU directives. For practical purposes, they are interchangeable.

EN ISO 15614-7 is a European Standard that outlines the requirements for the qualification of welding personnel for welding of metallic materials. Here's a comprehensive guide on the topic:

Do not trust websites offering "free PDF download" of ISO 15614-7. They often contain malware, outdated drafts, or scanned copies that are not searchable.

Compile all test certificates into the WPQR documentation to permanently qualify your workshop for the specific scope.

These are essential variables. Changing them without requalification invalidates the WPS.

Applying hardfacing alloys (like Stellite or tungsten carbides) to extend equipment life.

The official EN ISO 15614-7:2016 (the current version, adopted from ISO 15614-7:2016) is a 38‑page document, structured as follows:

Overlay welding does not primarily join two pieces together. Instead, it applies a layer of specialized alloy onto a base metal to improve surface properties. The primary goals are usually:

EN ISO 15614-7 defines how a welding procedure specification (WPS) for overlay welding is qualified by welding test pieces. It covers both corrosion-resistant and wear-resistant surfacing layers. Key Purposes
