The standard is the international benchmark for qualifying welding procedures for overlay welding . Industries worldwide rely on this standard to ensure that hardfacing and corrosion-resistant layers meet strict quality and safety requirements.

If a buffer layer is used between dissimilar materials (e.g., ferritic steel and austenitic overlay), this must also be qualified, often in conjunction with ISO 15614-1. Accessing the PDF

EN ISO 15614-7 belongs to the broader ISO 15614 series, which governs the qualification of welding procedures for metallic materials. While Part 1 focuses on standard butt and fillet welds, Part 7 isolates (also known as cladding or hardfacing).

The standard limits qualification to a specific base metal thickness (e.g., a test on 20mm plate qualifies you for 15mm to 40mm, not unlimited).

Before cutting the test coupon for destructive testing, the following NDT must be performed and passed: Accessing the PDF EN ISO 15614-7 belongs to

A cross-section is polished and etched to examine the weld run sequence, penetration profile, and heat-affected zone (HAZ).

Checking for surface cracks, undercut, or excessive reinforcement.
