EN ISO 15614 Weld Procedure Qualification Testing in Turbine Systems
The European standard EN ISO 15614-1:2009 provides a framework for the qualification and evaluation of welding procedures used in the manufacturing of pressure equipment, including turbine systems. This service is critical to ensuring that welds meet the stringent quality requirements set by this standard.
The primary purpose of Weld Procedure Qualification Testing (WPQT) as per EN ISO 15614-1:2009 is to verify the capability of a welding procedure in producing high-quality joints that meet specified performance criteria. This testing is essential for ensuring compliance with the relevant codes and standards, thereby safeguarding against potential failures within critical components such as those found in hydropower turbines.
In hydropower systems, turbine blades are subjected to extreme conditions including high temperatures, pressures, and corrosive environments. Ensuring that these components are manufactured using properly qualified welding procedures is paramount for operational safety and longevity of the equipment. WPQT involves several key steps:
- Welding Procedure Specification (WPS) Preparation: This document outlines all parameters necessary for producing a specific type of weld, including filler metal selection, joint design, welding position, heat input range, and post-weld treatment.
- Pre-Weld Inspection: Prior to performing the actual qualification tests, it's important to inspect the base material, groove geometry, and other critical aspects that could affect weld quality.
- Welding Procedure Qualification Testing (WPQT): Actual welding is performed on a test piece according to the specified WPS. This section includes multiple passes to ensure thorough testing of various conditions under which the final product will operate.
- Post-Weld Inspection: After completing the WPQT, inspections are conducted to evaluate the appearance and structure of the welds. Key factors include soundness (lack of defects), size and shape, and metallurgical properties like hardness distribution or microstructure.
The testing process also involves detailed documentation and analysis. Post-test reports must document all relevant data from the WPQT, including but not limited to:
- Welding procedure parameters (e.g., welding current, voltage, travel speed).
- Type of filler metal used.
- Visual examination results for surface imperfections.
- Non-destructive testing methods applied (such as radiography, ultrasonic testing).
- Mechanical property tests conducted on samples cut from the test specimens (hardness, tensile strength).
The outcome of this rigorous process determines whether a particular welding procedure can be considered qualified. If it passes all required evaluations and inspections, then that specific WPS is deemed acceptable for use in manufacturing parts like turbine blades or casings.
Given the importance of precision in hydropower applications where even minor flaws could lead to catastrophic failure, adhering strictly to EN ISO 15614-1:2009 ensures reliability and safety throughout the entire lifecycle of these complex systems.

Use Cases and Application Examples
Turbine Blade Manufacturing: Ensuring that the welding procedures used in producing turbine blades meet stringent quality standards is crucial for maintaining operational efficiency and safety. WPQT according to EN ISO 15614-1:2009 helps verify that these components will withstand the harsh environments they encounter during operation.
Turbine Housing Assemblies: For larger assemblies like turbine housings, WPQT ensures that all joints are strong enough to handle high-pressure and temperature variations without compromising performance or integrity over time. This is particularly important given their role in converting mechanical energy into electrical power efficiently while minimizing maintenance downtime.
Hydropower Plant Upgrades: When upgrading existing facilities, it's essential to ensure that new components are seamlessly integrated with old ones. WPQT helps verify compatibility between different materials and welding techniques used across various parts of the plant.
New Facility Construction: During initial construction stages, WPQT ensures that all welding procedures meet the specified criteria before any work proceeds further down the line. This reduces risks associated with rework or delays due to non-compliance issues later on in the project timeline.
