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)

ISO 15614-3:2008 specifies how a preliminary welding procedure specification (pWPS) for production and repair welding of non-alloyed and low-alloyed cast irons is qualified by fusion welding procedure tests.
ISO 15614-3:2008 defines the conditions for execution of the welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of a defined list of variables.
ISO 15614-3:2008 is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national standards or specifications. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests on a test piece made in accordance with ISO 15614-3:2008.
Additional tests may be required by application standards.
ISO 15614-3:2008 is applicable to welding non-alloyed and low-alloyed grey cast iron castings according to: EN 1561; EN 1562; EN 1563; and EN 1564.

Dieser Teil von ISO 15614 legt fest, wie eine vorläufige Schweißanweisung (pWPS) für die Fertigung und für die Reparatur von unlegierten und niedriglegierten Gusseisen durch Schweißverfahrensprüfungen qualifiziert wird. Sie gilt für das Schmelzschweißen.
Dieser Teil von ISO 15614 definiert die Bedingungen für die Durchführung der Schweißverfahrensprüfungen und den Geltungsbereich für Schweißverfahren für alle praktischen schweißtechnischen Tätigkeiten innerhalb des Bereiches der festgelegten Einflussgrößen.
Dieser Teil von ISO 15614 ist für alle neuen Schweißverfahren anwendbar. Er setzt jedoch bereits bestehende Schweißverfahrensprüfungen, die nach früheren nationalen Normen oder Regeln durchgeführt wurden, nicht außer Kraft. Wenn zusätzliche Prüfungen verlangt werden, um die Qualifizierungen technisch anzupassen, sind nur diese zusätzlichen Prüfungen an einem Prüfstück durchzuführen, das mit den Bestim¬mungen dieses Teils von ISO 15614 übereinstimmen sollte.
Zusätzliche Prüfungen dürfen durch die Anwendungsnormen gefordert werden.
Dieser Teil von ISO 15614 ist anwendbar für unlegierte und niedriglegierte Graugusseisenwerkstoffe in Übereinstimmung mit EN 1561, EN 1562, EN 1563 und EN 1564.

Overview

EN ISO 15614-3:2008 - "Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 3: Fusion welding of non-alloyed and low-alloyed cast irons" is a CEN-adopted ISO standard that specifies how a preliminary welding procedure specification (pWPS) for production and repair fusion welding of non-alloyed and low-alloyed cast irons is to be qualified. The standard defines execution conditions for welding procedure tests, the range of qualification (i.e., which variables are covered by a successful test), and the required examinations and acceptance criteria. It applies to grey, malleable, spheroidal graphite and austempered ductile cast irons cast to EN 1561/1562/1563/1564 and is also applicable in principle where cast iron is welded to steel or similar materials.

Key topics and technical requirements

• Qualification process: How to qualify a pWPS by performing a welding procedure test and recording results in a welding procedure qualification record (WPQR).
• Welding processes covered: Fusion processes in accordance with ISO 4063, including manual metal arc (MMA), MIG/MAG, TIG, submerged arc, flux-cored and related arc processes commonly used for cast iron repair and production.
• Test piece requirements: Shape, dimensions and preparation of specimens for procedure testing and for taking test coupons.
• Examination and testing: Mandatory non‑destructive testing (visual, penetrant as applicable) and destructive tests (macroscopic, mechanical tests) plus location and sampling of test specimens.
• Acceptance criteria and re‑testing: Criteria for accept/reject of welded test pieces and rules for re‑testing if necessary.
• Range of qualification: Variables and limits that define which production and repair operations are covered by the qualified WPS.
• Relation to previous tests: New standard does not invalidate earlier national qualifications; additional tests may be required only to demonstrate technical equivalence.

Applications and who uses it

• Welding engineers and procedure writers developing pWPS for cast iron production or in-service repair.
• Foundries, fabricators and maintenance teams performing finishing or repair welding on grey, malleable, spheroidal or austempered ductile castings.
• Welding inspectors and quality managers responsible for WPQR validation, NDT and acceptance decisions.
• Certification bodies and purchasers who require standardized qualification of welding procedures for cast iron components.

Related standards

• ISO 15607 (general rules for welding procedure specification/qualification)
• ISO 15609-1 / ISO 15609-2 (WPS formats)
• EN 1561 / EN 1562 / EN 1563 / EN 1564 (cast iron material standards)
• EN 571-1, EN 970 (NDT/visual), EN 1321 (macroscopic/microscopic examination)
• EN 1011-8 (welding recommendations for cast irons)

EN ISO 15614-3:2008 is essential for consistent, auditable qualification of fusion welding procedures on cast iron - improving repeatability, safety and component reliability in production and repair welding.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
