Overlay welding plays a critical role in modern engineering by extending the lifespan of industrial components. Instead of fabricating entire structures from expensive, corrosion-resistant alloys, engineers use a cost-effective base metal and apply a protective layer on top.

The test piece must undergo both non-destructive testing (NDT) and destructive testing, as required by the standard: To check for surface defects.

While older drafts might be found online (e.g., ⁠prEN ISO 15614-7:2002 ), always prioritize the published 2021 edition.

The standard dictates explicit sizing for overlay test sheets or pipes to ensure that thermal cooling cycles and stress distributions realistically represent production conditions:

Many professionals mistakenly search for weld cladding qualifications under , which covers butt and fillet welds. However, Part 1 does not adequately address the unique challenges of overlay welding—specifically, dilution control and chemical composition verification.
