Overview
EN ISO 15614-14:2013 / ISO 15614-14:2013 - Specification and qualification of welding procedures for metallic materials - Part 14 sets out how a preliminary welding procedure specification (PWS) is qualified by welding procedure tests for laser‑arc hybrid welding of steels, nickel and nickel alloys. Published by ISO and endorsed by CEN (as EN ISO 15614-14:2013), the standard defines the conditions for executing welding procedure tests and the permitted range of qualification for practical welding operations within the variables listed in Clause 8.
Key topics and requirements
- Welding procedure test scope: Describes how to qualify a PWS by performing welding procedure tests and documenting results in a Welding Procedure Qualification Record (WPQR).
- Test piece and welding execution: Requirements for preparation, shape and dimensions, and welding of test pieces (see Clause 6).
- Examination and testing: Specifies non‑destructive and destructive examinations, specimen locations and testing extent (Clause 7).
- Range of qualification (Clause 8): Defines parameters that affect the qualification range, including:
- manufacturer and parent material attributes
- welding process variables and position
- joint/weld type, number of layers, filler material
- preheat/interpass and post‑weld heat treatment
- nominal heat input and validity duration
- WPQR and documentation: Guidance for preparing the Welding Procedure Qualification Record; an informative WPQR template is provided in Annex A.
- Quality levels and re‑testing: Addresses acceptable imperfection levels and conditions for retest.
Practical applications and users
EN ISO 15614-14 is essential for organizations implementing or qualifying laser‑arc hybrid welding procedures where consistent, documented welding performance is required. Typical users include:
- Welding engineers and procedure developers
- Quality assurance / quality control personnel
- Fabricators and welding contractors using laser‑arc hybrid systems
- Certification bodies and inspectors assessing procedure qualification
- Industries employing high‑productivity welding - e.g., heavy fabrication, pressure vessels, energy, and transportation sectors
Applying this standard helps ensure reproducible weld quality, traceable qualification records (WPQR), and conformity with client or regulatory requirements for welded assemblies made from steels and nickel alloys.
