En Iso 15614-7 Pdf -
The EN ISO 15614-7 standard is a critical document for welding engineers and manufacturers focusing on overlay welding (also known as surfacing, cladding, or hardfacing). It establishes the rules for qualifying welding procedures to ensure that the deposited metal meets specific corrosion-resistant or wear-resistant requirements. Key Overview of EN ISO 15614-7
Purpose: It specifies how a preliminary Welding Procedure Specification (pWPS) is qualified through welding procedure tests.
Scope: This part of the 15614 series specifically covers overlay welding on metallic materials. It does not cover "building up" or "repair welding," which are typically handled by ISO 15614-1 or ISO 15613.
Applicability: It applies to all arc and gas welding processes suitable for surfacing. Essential Requirements for Qualification
To qualify a procedure under this standard, manufacturers must conduct specific tests on a test piece, including: Visual Testing: Checking for surface defects.
Non-Destructive Testing (NDT): Often includes penetrant or magnetic particle testing.
Destructive Testing: This is where Part 7 gets specific, often requiring:
Macroscopic Examination: To check fusion and layer thickness.
Hardness Testing: Crucial for hardfacing applications to verify wear resistance.
Chemical Analysis: Ensuring the surface layer has the correct alloy composition.
Bend Tests: Verifying the bond between the overlay and parent metal. How to Access the Official PDF

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: Scope of EN ISO 15614-7 The scope of
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.
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

In the world of high-stakes industrial manufacturing, EN ISO 15614-7 is not just a document; it is the "law of the land" for overlay welding
. This standard specifies how to qualify a preliminary welding procedure specification (pWPS) specifically for adding layers of protective material to a base metal. The Story of the Shielded Reactor
Imagine a heavy-duty chemical reactor designed to hold highly corrosive acid. The base metal of the reactor is strong enough to hold the pressure, but it would dissolve in minutes without a special protective lining. To save the vessel, engineers decide to use overlay welding (also known as cladding or hardfacing).

These are essential variables. Changing them without requalification invalidates the WPS.
