EN ISO 15614-1:2017 PDF

Overview

EN ISO 15614-1:2017 - Specification and qualification of welding procedures for metallic materials - Part 1: Welding procedure test - covers the qualification process for preliminary welding procedure specifications (pWPS) for arc and gas welding of steels and arc welding of nickel and nickel alloys. The standard defines how welding procedure tests are executed, the test-piece requirements, and the resulting range of qualification for production, repair and build‑up welding. Its primary purpose is to demonstrate that a proposed joining process can produce joints with the required mechanical properties.

Key topics and requirements

• Qualification levels: Two test levels are specified - Level 1 (broader ranges, less extensive testing) and Level 2 (more restrictive ranges, greater testing). Level 2 tests automatically cover Level 1; if no level is specified, Level 2 applies.
• Scope of processes: Applies to arc and gas welding in all product forms for steels and to arc welding of nickel/nickel alloys. Covered welding processes (ISO 4063 numbers) include:
  • 111 - manual metal arc (SMAW)
  • 114 - self-shielded flux-cored arc
  • 12 - submerged arc welding
  • 13 - gas-shielded metal arc (GMAW/MIG)
  • 14 - gas-shielded arc with non‑consumable electrode (GTAW/TIG)
  • 15 - plasma arc welding
  • 311 - oxy-acetylene welding
• Test pieces and preparation: The standard defines shapes, dimensions and welding practice for test pieces (butt joints, pipe joints, T‑joints, branch connections) and allows principles to be applied to other fusion processes.
• Examination and testing: Specifies non‑destructive testing (NDT) and destructive testing requirements, including transverse tensile, bend tests, macroscopic examination, impact testing and hardness testing. It defines test specimen locations, acceptance levels and re‑testing rules.
• Range of qualification: Rules cover manufacturer-related factors, parent material grouping, thickness/diameter ranges, welding positions, joint types, filler materials, heat input and current types.
• Legacy qualifications: Procedure qualifications from previous editions remain usable; existing WPQRs can be extended to the 2017 edition if the technical intent is met (additional tests only where necessary).

Applications and users

• Useful for fabricators, Welding Procedure Qualification Record (WPQR) authors, welding engineers, quality managers, and inspectors in industries such as pressure‑equipment manufacturing, petrochemical, shipbuilding and structural steelwork.
• Supports compliance with EU directives (see Annexes ZA/ZB) for pressure equipment (PED) and simple pressure vessels (SPVD) by providing a voluntary route to conformity.

Related standards

• ISO 4063 (welding process classification)
• National or industry application standards that specify which qualification level to apply (e.g., contract specifications referencing EN ISO 15614-1:2017)
