Many professionals mistakenly search for weld cladding qualifications under ISO 15614-1, 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.
| Feature | EN ISO 15614-1 | EN ISO 15614-7 | | :--- | :--- | :--- | | Primary Focus | Butt/fillet welds in plates & pipes | Overlay/cladding layers | | Key Test | Tensile & impact testing | Chemical analysis & macro exam | | Dilution Concern | Low | Critical | | Layer Buildup | Not applicable | Single & multi-layer |
Thus, if your project requires cladding a carbon steel vessel with Inconel 625 or stainless steel 316L, you must reference EN ISO 15614-7.
The standard defines "essential variables"—parameters that, if changed beyond a certain range, require re-qualification. These include:

EN ISO 15614-7 is the international standard governing the specification and qualification of welding procedures for overlay welding. Unlike Part 1, which focuses on butt and fillet welds, Part 7 specifically handles the application of surfacing materials, such as corrosion-resistant overlays or hardfacing. Key Overview of the Standard
Purpose: It defines how a preliminary welding procedure specification (pWPS) for overlaying is qualified through standardized tests.
Applications: Specifically covers corrosion-resistant overlays, hardfacing, and other surface treatments. It does not apply to standard build-up or repair of parent metal, which are covered by ISO 15614-1 or ISO 15613.
Current Version: The most recent harmonized European version is EN ISO 15614-7:2019, which adopts the international ISO 15614-7:2016 text. Core Components & Requirements
The standard outlines strict conditions for the execution of qualification tests, including:
Range of Qualification: Defines the limits of variables (such as material thickness, overlay thickness, and welding position) under which the qualification remains valid.
Examination and Testing: Requires a combination of non-destructive testing (NDT), such as penetrant inspection, and destructive testing to verify the integrity of the overlay. en iso 15614-7 pdf
Buttering: 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
While official standards must be purchased, technical previews and historical drafts are often indexed on academic or document-sharing platforms:
Official Sources: Full documents are available through national standards bodies like the BSI Knowledge Store or the ISO Store.
Drafts/Previews: Publicly accessible previews and draft fragments can sometimes be found on platforms like Scribd or iTeh Standards.

EN ISO 15614-7 is the international standard governing the specification and qualification of welding procedures for overlay welding
. It specifically addresses how a preliminary welding procedure specification (pWPS) is qualified through rigorous welding procedure tests. Core Purpose and Scope Target Applications
: The standard applies to all welding processes suitable for overlay welding , which includes both corrosion-resistant overlays hardfacing Qualification Method
: It defines the exact conditions for carrying out tests and establishes the "range of qualification"—essentially the boundaries within which a welding procedure remains valid once tested. Exclusions
: It generally does not apply to specialized applications where cracks are intentionally produced, such as certain types of unique hardfacing. Key Technical Components
The standard outlines a structured process for ensuring weld quality: Test Pieces Welding Processes : The standard covers various welding
: Specifies the required dimensions and types of test pieces that must be welded to prove the procedure. Examination and Testing : Detailed requirements for both Non-Destructive Testing (NDT) —like visual or ultrasonic testing—and destructive testing to verify the overlay's integrity. Variables (Clause 8)
: Lists critical variables (like material type or welding position) that, if changed beyond a certain limit, require a new procedure test. iTeh Standards Current Status and Versions EN ISO 15614-7:2019 : This is the current European adoption of the ISO 15614-7:2016 international standard. Relationship to Other Standards

A: You have three options: (a) Reject the procedure and start over. (b) Add another pass to reduce dilution (if the test piece allows). (c) Change parameters to lower heat input. You cannot "repair" a failed test without a new test piece.
EN ISO 15614-7 is part of the larger ISO 15614 series, which deals with the specification and qualification of welding procedures for metallic materials.
Specifically, Part 7 is titled: “Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 7: Overlay welding.”
While other parts of the series focus on joining two pieces of metal together (butt welds, fillet welds), Part 7 focuses on Surface Welding. This is the process of applying a layer of metal onto a base metal to improve corrosion resistance, wear resistance, or to restore dimensions.
In the world of industrial welding, integrity is everything. Whether you are creating a corrosion-resistant layer inside a chemical reactor or building up a worn shaft, the quality of the weld overlay determines the lifespan of the component. This is where EN ISO 15614-7 becomes indispensable.
If you have searched for "en iso 15614-7 pdf", you are likely a welding engineer, a quality assurance manager, or a fabrication inspector. You need access to the precise rules for qualifying your welding procedures for cladding, hardfacing, and surfacing.
This article provides a deep dive into the requirements of EN ISO 15614-7, explains why finding the official standard is critical, and outlines how to use the specification correctly.
