This document applies to types of joint preparation for submerged arc welding with one wire electrode (process 121 according to ISO 4063) on steel.
This document covers only the welding positions PA and PB according to ISO 6947. If PC is used, special preparation is necessary.
This document applies to fully penetrated welds. For partly penetrated welds, types of joint preparation, shapes and dimensions can differ from the listed proposals if they are specified in the relevant application standard or agreed by the parties concerned.

Dieses Dokument ist für volldurchschweißte Nähte anwendbar. Bei teilweise durchgeschweißten Nähten können die Art der Schweißnahtvorbereitung, Formen und Maße von den aufgeführten Vorschlägen abweichen, wenn diese in der entsprechenden Anwendungsnorm oder in einer Vereinbarung zwischen den beteiligten Vertragspartnern festgelegt sind.
Soudage et techniques connexes - Préparation de joints - Partie 2: Soudage à l'arc sous flux en poudre des aciers (ISO 9692-2:2024)
Le présent document spécifie les types de préparation de joints pour soudage sous flux avec fil-électrode sur acier (procédé 121 conformément à I’ISO 4063).
Le présent document couvre seulement les positions de soudage PA et PB conformément à I’ISO 6947. Si la position PC est utilisée, une préparation spéciale est nécessaire.
Le présent document est applicable aux soudures à pleine pénétration. Dans le cas de soudures à pénétration partielle, les types de préparation de joints, les formes et dimensions peuvent être différents de ceux des exemples proposés ici s’ils sont spécifiés dans la norme d’application correspondante ou s’ils font l’objet d’un accord entre les parties concernées.

Ta del standarda ISO 9692 se uporablja za vrste priprave zvarnih stikov za varjenje jekla pod praškom z eno žično elektrodo (postopek 121 v skladu s standardom ISO 4063).
Ta del standarda ISO 9692 zajema samo položaja pri varjenju PA in PB v skladu s standardom ISO 6947. V primeru uporabe položaja PC je potrebna posebna priprava.
Uporablja se za zvare s popolno prevaritvijo. Pri zvarih z delno prevaritvijo se lahko vrste priprave zvarnih robov, oblike in dimenzije razlikujejo od navedenih predlogov, če so podane v ustreznem standardu za uporabo oziroma so se o njih dogovorile zadevne stranke.
Če se za varjenje korena uporablja drugačen postopek obločnega varjenja (glej standard ISO 40631), je treba upoštevati pripravo zvarnih robov iz standarda ISO 9692.

Overview
EN ISO 9692-2:2024 - Welding and allied processes - Joint preparation - Part 2: Submerged arc welding of steels specifies recommended types of joint preparation for submerged arc welding (SAW) using a single wire electrode (process 121, ISO 4063) on steels. The document is the 2024 edition adopted by CEN (EN ISO 9692-2:2024) and applies primarily to fully penetrated welds in welding positions PA and PB (ISO 6947). It provides standardized joint geometries, reference numbers and dimensional guidance presented in Table 1 and Table 2 for butt welds welded from one or both sides.
Key topics and technical requirements
- Scope and applicability
- Applies to SAW of weldable steels with one wire electrode (process 121).
- Covers only PA and PB welding positions; use of position PC requires special preparation.
- Intended for fully penetrated welds; partly penetrated joints can deviate if specified by the application standard or agreed by parties.
- Joint types and dimensions
- Recommends joint types (square butt, single‑V, single‑U, single‑bevel, single‑J, double‑V, etc.) and dimensional ranges in Table 1 (one‑sided welds) and Table 2 (both‑sided welds).
- Reference numbering aligns with ISO 2553 conventions.
- Root and backing guidance
- Root gaps are specified after tack welding, if tacks are used.
- The standard does not specify backing material types or dimensions; root runs may serve as backing. Any backing or root run must be included in the welding procedure specification (WPS).
- Process and quality interactions
- Notes that use of root runs, backing and slag removal (grinding before subsequent runs) can affect weld quality and should be addressed in accordance with relevant quality requirements (e.g., ISO 3834) and welding procedure specification requirements (ISO 15609-1).
Practical applications
- Use this standard when specifying joint preparation for SAW on steel structures, pressure parts, heavy fabrication, pipe and plate work where a single‑wire SAW process is used.
- Useful for:
- Preparing welding procedure specifications (WPS) and shop drawings.
- Selecting joint geometries to optimise penetration, deposition rates and productivity for SAW.
- Communicating dimensional tolerances between designers, welders and inspectors.
- Helps ensure consistency across manufacturing, inspection and contractual documentation for SAW applications.
Who should use this standard
- Welding engineers and fabricators
- Procedure writers and QA/QC inspectors
- Design engineers specifying welded joints
- Standards and compliance officers in steel fabrication and heavy industry

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
