Overview
EN ISO 10042:2018 (ISO 10042:2018) defines acceptance quality levels for imperfections in arc‑welded joints made from aluminium and its alloys. Applicable to material thicknesses > 0.5 mm, the document provides standardized dimensional limits and acceptance criteria for common imperfections found in production welding. It is intended as a reference for drafting application codes and for specifying production quality (not fitness‑for‑purpose) across a wide range of welded constructions.
Key topics
- Quality levels B, C and D: three graded acceptance levels (B = most stringent) to suit different fabrication and inspection needs.
- Types of welds covered: butt welds, fillet welds, branch connections and other joint forms.
- Welding processes: metal inert gas (MIG/GMAW), tungsten inert gas (TIG/GTAW) and plasma arc welding; applies to manual, mechanized and automatic welding in all positions.
- Imperfections addressed: dimensional limits for porosity, cracks, undercut, incomplete fusion/penetration and other typical arc‑welding defects (selection based on ISO 6520‑1 classifications).
- Inspection scope: directly applicable to visual testing of welds; correlation to other NDT methods (UT, RT, PT) requires additional reference (see ISO 17635).
- Normative references and annexes: references ISO 6520‑1 (classification of geometric imperfections) and includes informative annexes (e.g., percent porosity examples and user guidance).
- Limitations: does not cover metallurgical properties (grain size, hardness) or specify fitness‑for‑purpose - those are determined by the application standard, designer or purchaser.
Applications and users
EN ISO 10042:2018 is widely used for:
- Writing contractual or procurement acceptance criteria for aluminium fabrication.
- Establishing inspection and quality control plans in production welding.
- Guiding welding engineers, QA/QC inspectors and technicians on acceptable defect sizes.
- Assisting designers and specifiers in selecting appropriate production quality levels based on service conditions, loading and economics.
Typical users: welding engineers, fabrication shops, quality managers, inspection bodies and standards authors in industries working with aluminium structures and components.
Related standards
- ISO 6520‑1 - classification of geometric imperfections (normative reference).
- ISO 17635 - correlation between quality levels and non‑destructive testing methods.
- ISO 2553 - fillet weld throat definitions (referenced for dimensions).
- ISO 5817 - related defect descriptions used in welding standards.
EN ISO 10042:2018 helps organizations standardize acceptance of weld imperfections, streamline inspection criteria, and align production quality expectations across aluminium welding projects.

ISO 10042:2018(E)
Introduction
This document is intended to be used as a reference in drafting application codes and/or other
application standards. It contains a simplified selection of arc welding imperfections based on the
designations given in ISO 6520-1.
Some imperfections described in ISO 6520-1 have been used directly while others have been grouped
together. The basic numerical referencing system from ISO 6520-1 has been used.
The purpose of this document is to define the dimensions of typical imperfections which can be
expected in normal fabrication. It can be used within a quality system for the production of welded
joints. It provides three sets of dimensional values from which a selection can be made for a particular
application. The quality level necessary in each case needs to be defined by the application standard or
the responsible designer, in conjunction with the manufacturer, user and/or other parties concerned.
The quality level are prescribed before the start of production, preferably at the enquiry or order stage.
For special purposes, additional details can be necessary.
The quality levels given in this document provide basic reference data and are not specifically related
to any particular application. They refer to the types of welded joint in fabrication and not to the
complete product or component itself. It is possible, therefore, that different quality levels are applied
to individual welded joints in the same product or component.
It is normally be expected that, for a particular welded joint, the dimensional limits for imperfections
can all be covered by specifying one quality level. In some cases, it can be necessary to specify different
quality levels for different imperfections in the same welded joint.
The choice of quality level for any application takes account of design considerations, subsequent
processing (e.g. surfacing), mode of stressing (e.g. static, dynamic), service conditions (e.g. temperature,
environment) and consequences of failure. Economic factors are also important and include not only
the cost of welding but also of inspection, test and repair.
Although this document includes types of imperfection relevant to the arc welding processes given in
Clause 1, only those which are applicable to the process and application in question are considered.
Imperfections are quoted in terms of their actual dimensions, and their detection and evaluation
can require the use of one or more methods of non-destructive testing. The detection and sizing of
imperfections is dependent on the testing methods and the extent of testing specified in the application
standard or contract.
This document does not address the methods used for the detection of imperfections. However,
ISO 17635 contains a correlation between the quality level and acceptance level for different NDT (non-
destructive testing) methods.
This document is directly applicable to visual testing of welds and does not include details of
recommended methods of detection or sizing by other non-destructive means. There are difficulties
in using these limits to establish appropriate criteria applicable to NDT methods such as ultrasonic
(UT), radiographic (RT) and penetrant testing (PT), for which additional requirements for testing can
be necessary.
The values given for imperfections are for welds produced using normal welding practice. Requirements
for smaller (more stringent) values as stated in quality level B can include additional manufacturing
processes, e.g. grinding, TIG dressing.

The standard EN ISO 10042:2018 provides a comprehensive document detailing the quality levels for imperfections in arc-welded joints specifically in aluminum and its alloys. Spanning a pertinent scope, this standard applies to materials exceeding a thickness of 0.5 mm, thereby ensuring its relevance in a range of industrial applications. One of the key strengths of EN ISO 10042:2018 is its clear classification of three distinct quality levels, labeled as B, C, and D. This categorization allows for flexibility and adaptability in various welded constructions, promoting a tailored approach to quality assurance based on specific project requirements. Quality Level B, which signifies the highest standards for finished welds, is particularly notable for sectors where precision and integrity of the welded joints are paramount. The standard's applicability extends to a variety of welding methods, including but not limited to MIG welding, TIG welding, and plasma arc welding. This broad scope ensures it can be utilized across different welding techniques and positions, whether executed manually, mechanized, or automatically, addressing diverse manufacturing contexts. Additionally, while the standard provides extensive guidance on production quality levels, it explicitly clarifies that these levels do not correlate with the product's fitness for purpose. This distinction emphasizes the importance of quality assurance while allowing manufacturers to align their processes with specific functional requirements. Furthermore, the exclusion of metallurgical aspects, such as grain size and hardness, reinforces the focus of EN ISO 10042:2018 on the quality of the weld itself rather than the underlying material properties. This targeted approach enables manufacturers to concentrate on the visible and functional integrity of welded joints, thereby enhancing overall product reliability. In conclusion, EN ISO 10042:2018 stands out as a pivotal guideline for industries dealing with arc-welded aluminum joints by providing clear quality benchmarks, extensive applicability, and a focused approach to assessing imperfections in welds. Its structured framework promotes consistency in quality assurance, making it an essential reference for professionals in the welding sector.
Die EN ISO 10042:2018 ist ein entscheidendes Dokument, das Qualitätsniveaus für Unregelmäßigkeiten in elektrisch geschweißten Verbindungen aus Aluminium und seinen Legierungen festlegt. Der Geltungsbereich dieser Norm ist klar definiert und richtet sich an Schweißverbindungen für Materialdicken von mehr als 0,5 mm. Dies macht die Norm für eine Vielzahl von Anwendungen in der Aluminiumverarbeitung und -konstruktion äußerst relevant. Ein herausragendes Merkmal der EN ISO 10042:2018 ist die Festlegung von drei Qualitätsniveaus, die den symbolischen Bezeichnungen B, C und D zugeordnet sind. Diese Stufen ermöglichen eine breite Anwendbarkeit auf verschiedene Schweißkonstruktionen, angefangen bei hochkomplexen bis hin zu einfacheren Anwendungen. Qualitätsebene B, die die höchsten Anforderungen an die fertige Schweißnaht stellt, hebt die Bedeutung der Schweißqualität in der industriellen Praxis hervor. Die Norm deckt eine Vielzahl von Schweißverfahren ab, darunter Metall-Inertgas-Schweißen (MIG), Wolfram-Inertgas-Schweißen (TIG) und Plasmaschweißen, und legt somit den Grundstein für eine konsistente Qualitätskontrolle in unterschiedlichen Schweißpositionen und -techniken. Diese Flexibilität und Breite der Anwendbarkeit zeigen die Relevanz der Norm für moderne Fertigungsprozesse, die sowohl manuelles als auch automatisches Schweißen umfassen. Darüber hinaus konzentriert sich die EN ISO 10042:2018 auf Produktionsqualität und legt nicht die Eignung des Endprodukts für bestimmte Anwendungen fest. Dies gibt Herstellern die Möglichkeit, ihre Schweißprozesse an die spezifischen Anforderungen ihrer Produkte anzupassen, während gleichzeitig die Qualitätsstandards gewährleistet werden. Insgesamt schafft die EN ISO 10042:2018 einen klaren Rahmen für die Qualitätsbewertung von Schweißnähten aus Aluminium und unterstützt damit Hersteller dabei, qualitativ hochwertige und zuverlässige Produkte zu liefern. Die Norm ist somit ein unverzichtbares Werkzeug für alle, die im Bereich der Aluminiumverarbeitung tätig sind und höchste Qualitätsansprüche vertreten.
