Abstract

Standard that specifies how a preliminary welding procedure specification (pWPS) for overlay welding (corrosion‑resistant overlays and hardfacing) is qualified by welding procedure tests. It defines test-piece geometry and welding conditions, required non‑destructive and destructive examinations and acceptance criteria, the form and content of the WPQR, and the range of qualification variables (materials, filler, process, overlay thickness, position, heat input, preheat/interpass/post‑weld heat treatment, number of layers, etc.).

Scope

This part of ISO 15614 specifies the method for qualifying welding procedures for overlay welding (re‑surfacing, cladding, hardfacing) by means of welding procedure tests. It applies to both corrosion‑resistant overlay welding and hardfacing applications and covers practical welding operations within the range of variables listed in Clause 8 (materials, filler metals, welding processes, overlay thickness, number of layers, position, current type, arc energy, preheat/interpass/post‑weld heat treatment, etc.). Application standards may require additional tests.

Key topics and requirements

• Definition and preparation of a preliminary Welding Procedure Specification (pWPS) for overlay welding.
• Requirements for welding procedure qualification tests (WPQT) including test‑piece geometry and welding procedure parameters.
• Non‑destructive testing (extent and acceptance criteria) and destructive testing (macroscopic examination, hardness testing, side‑bend tests, chemical analysis, ferrite content where applicable).
• Acceptance criteria and re‑testing procedures for detected imperfections.
• Range of qualification: which variations (material manufacturer, filler designation, overlay thickness, process, position, current type, arc energy, preheat/interpass/post‑weld heat treatment, number of layers, etc.) are covered by a single qualification.
• Process‑specific restrictions and additional requirements (e.g., plasma, plasma transferred arc (PTA), submerged arc, electroslag overlay, oxy‑acetylene, manual processes, and filler feed/powder characteristics where relevant).
• Form and content of the Welding Procedure Qualification Record (WPQR) to document the qualified procedure for later use in production pWPS/WPS control.

Summary of principal clauses and practical requirements for qualifying overlay welding procedures.

Typical use and users

Used by welding engineers, procedure developers, fabricators and workshops that perform corrosion‑resistant overlays or wear hardfacing; quality and inspection personnel (NDT technicians, QA/QC inspectors); third‑party conformity assessors; and specifiers or purchasers requiring qualified overlay welding procedures (including applications subject to pressure‑equipment or safety requirements). It is commonly used to establish WPQRs and control production welding under an approved pWPS.

Related standards

Related standards and normative references typically include other parts of ISO 15614 (e.g., ISO 15614‑1), ISO 15613, relevant EN/ISO standards for NDT and weld testing (ISO 17637, ISO 17405), ISO 3452‑1 (penetrant testing) and process‑specific or material application standards. National adoption documents list normative cross‑references and complementary standards used together with this part.

FAQ

Q: What is this standard?

A: It is the national adoption (UNE‑EN ISO 15614‑7:2020) of ISO 15614‑7 (Part 7 of the ISO 15614 series), which specifies how overlay welding procedures are qualified by welding procedure tests.

Q: What does it cover?

A: It covers the qualification process for overlay welding procedures (both corrosion‑resistant overlay and hardfacing), specifying test-piece preparation, test execution, required examinations and tests (NDT and destructive), acceptance criteria, and the allowable range of variables covered by a single qualification.

Q: Who typically uses it?

A: Welding engineers, procedure writers, fabricators doing cladding or hardfacing, NDT and QA/QC personnel, third‑party inspectors, and specifiers who require validated welding procedures for safety‑critical or corrosion/wear‑resistant applications.

Q: Is it current or superseded?

A: The UNE edition was published on 23 September 2020 and is listed as the current (vigente) national adoption; it is identical to the international text ISO 15614‑7:2016 and to the European adoption EN ISO 15614‑7:2019 as referenced in the national record. Corrections or corrigenda applied to the UNE text are noted by the publisher.

Q: Is it part of a series?

A: Yes — it is Part 7 of the ISO 15614 series (Specification and qualification of welding procedures for metallic materials — Welding procedure test). The series includes multiple parts covering different welding processes and materials (for example ISO 15614‑1 for arc and gas welding of steels and nickel alloys).

Q: What are the key keywords?

A: Overlay welding, cladding, hardfacing, welding procedure test, WPQR, pWPS, WPS, qualification, NDT, destructive testing, acceptance criteria.
