En Iso 15614-7 | Pdf Repack
EN ISO 15614-7:2019 defines requirements for qualifying welding procedures for overlay welding, covering corrosion-resistant, hardfacing, and build-up applications. It ensures that welding procedure tests are conducted for metallic materials, validating specifications used in industries like petrochemical and power generation.

ISO 15614-7:2016 - Overlay Welding Procedure Specification and en iso 15614-7 pdf
Key Details of the Standard:
- Full Title: EN ISO 15614-7:2016 (current version)
- Scope: Qualification of welding procedures for overlay welding using any fusion welding process.
- Application: Corrosion-resistant overlays (CRA) and wear-resistant layers.
- Key Industries: Oil & gas, petrochemical, power generation, pressure vessels, and offshore structures.
Why is this Standard Important?
The overlay process is commonly used in high-stakes industries. Key Details of the Standard:
- Oil & Gas: Cladding the inside of pipes and valves with corrosion-resistant alloys (like Inconel or Stainless Steel) to protect against sour gas (H2S) or CO2.
- Power Generation: Repairing turbine blades or cladding boiler tubes to resist high-temperature erosion.
- Mining: Hardfacing excavator buckets and crushers to extend their service life.
By adhering to EN ISO 15614-7, manufacturers ensure that the cladding will not spall (flake off) and will provide the chemical resistance required for the asset's design life. Full Title: EN ISO 15614-7:2016 (current version) Scope:

What is EN ISO 15614-7?
EN ISO 15614-7:2016 is a European Adoption of an International Standard titled: "Specification and qualification of welding procedures for metallic materials – Welding procedure test – Part 7: Overlay welding."
It is part of the ISO 15614 series, which dictates how to qualify a Welding Procedure Specification (WPS) via a Welding Procedure Qualification Record (WPQR). Unlike other parts of the series (e.g., Part 1 for arc welding of steels), Part 7 specifically addresses surfacing—applying a layer of weld metal onto a base material to achieve specific surface properties.
