Full title and description

Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 3: Fusion welding of non‑alloyed and low‑alloyed cast irons (ISO 15614‑3:2008). This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for production and repair welding of non‑alloyed and low‑alloyed cast irons is qualified by welding procedure tests, and defines the conditions for executing tests and the range of qualification for practical welding operations.

Abstract

ISO 15614‑3:2008 covers qualification of welding procedures for fusion welding of non‑alloyed and low‑alloyed grey cast irons, describing required test pieces, test methods, acceptance criteria and the range of qualification of the resulting welding procedure specification. It is applicable to new welding procedures and provides principles that may also be used when welding cast iron to steel or other similar materials. Additional tests may be required by application standards.

Scope

This standard specifies the method for qualifying a preliminary welding procedure specification (pWPS) by means of welding procedure tests for fusion welding of unalloyed and low‑alloyed cast irons (grey cast iron). It defines testpiece geometry and preparation, required tests and examinations, allowable range of qualification and limits of applicability; it is intended for production and repair welding and does not invalidate earlier national procedure tests unless additional tests are required to achieve technical equivalence.

Key topics and requirements

• Qualification of a pWPS by welding procedure tests (weld execution, sampling and examination).
• Test‑piece design, machining and preparation requirements for cast‑iron test specimens.
• Range of qualification (variables affecting applicability) and limits for transferability to production joints.
• Required mechanical and metallurgical tests and acceptance criteria for cast iron welds.
• Reference to preparation of pWPS in accordance with ISO 15609 series and use of ISO 15611/ISO 15613 when testpiece geometry differs from production geometry.
• Applicability to grey cast irons cast to EN 1561, EN 1562, EN 1563 and EN 1564 and principles for welding cast iron to steel or similar materials.

Typical use and users

Used by welding engineers, procedure qualification laboratories, QA/QC personnel, fabricators and repair workshops that weld grey cast iron components. Typical application areas include foundry repairs, maintenance of cast iron machinery, pipelines and components where fusion welding of unalloyed or low‑alloyed cast irons is required.

Related standards

ISO 15614 is a multi‑part series; related documents include other parts of ISO 15614 (different materials and processes), ISO 15609 (specification of WPS formats), ISO 15611 and ISO 15613 (alternative testpiece and qualification procedures), and relevant EN/ISO material standards for cast irons (EN 1561, EN 1562, EN 1563, EN 1564). National/adopted versions (e.g., EN ISO 15614‑3) contain the same technical content with national forewords where applicable.

FAQ

Q: What is this standard?

A: ISO 15614‑3:2008 is an international standard specifying how to qualify welding procedures for fusion welding of non‑alloyed and low‑alloyed (grey) cast irons by welding procedure tests.

Q: What does it cover?

A: It covers preparation of a preliminary welding procedure specification (pWPS), execution of welding procedure tests, test‑piece requirements, required examinations and mechanical tests, acceptance criteria and the defined range of qualification for practical welding operations on cast iron.

Q: Who typically uses it?

A: Welding engineers, procedure qualification laboratories, fabricators and maintenance/repair workshops working with grey cast iron, plus certification and QA personnel responsible for approving welding procedures.

Q: Is it current or superseded?

A: As published in March 2008, ISO 15614‑3:2008 remains the official text from ISO; its published lifecycle is subject to periodic review (ISO standards are typically reviewed every five years) — users should check national adoption status or ISO catalog entries for any subsequent confirmations or revisions applicable to their region or sector.

Q: Is it part of a series?

A: Yes — ISO 15614 is a multipart series covering welding procedure tests for various materials and processes (other parts address aluminium, titanium, steels, electron/laser welding, spot/seam welding, etc.). ISO 15609, ISO 15611 and ISO 15613 are commonly referenced in the series for WPS format and alternative test methods.

Q: What are the key keywords?

A: pWPS, welding procedure test, fusion welding, grey cast iron, procedure qualification, test piece, acceptance criteria, ISO 15614.
