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:
For engineers, welding inspectors, and quality managers searching for the , the goal is usually twofold: first, to understand what the standard mandates, and second, to obtain a legitimate copy for daily operations. This article serves as a comprehensive guide to EN ISO 15614-7, its scope, its importance in cladding applications, and how to properly access the PDF version.

The scope of EN ISO 15614-7 includes:
: Ensures the dilution with the parent metal does not compromise the overlay's performance. Overlay welding does not primarily join two pieces together
This standard applies to all welding processes suitable for overlaying, including: Corrosion-resistant overlays : Protecting base metals from chemical degradation. Hardfacing : Increasing resistance to wear and impact. : Creating a transition layer between dissimilar materials. : Restoring dimensions to parent metals.
: Platforms like IHS Markit or Techstreet offer secure corporate access.

But more specifically, if you were designing a search tool or a database filter for this, the most useful feature would be:
: To check for surface irregularities and profile defects.
