Full title and description

ISO 13918:2017 — Welding — Studs and ceramic ferrules for arc stud welding, together with Amendment 1 (ISO 13918:2017/Amd 1:2021) which updates/clarifies parts of the 2017 edition. The standard specifies dimensional, material and mechanical requirements for studs and ceramic ferrules used in arc stud welding applications, and includes related ordering and conformity information.

Abstract

This International Standard defines requirements for studs and ceramic ferrules for arc stud welding, including dimensions, materials and mechanical properties and, where applicable, conditions for evaluation of conformity. Amendment 1 (2021) provides a small update to the 2017 edition.

Scope

ISO 13918:2017 specifies requirements for studs and ceramic ferrules intended for arc stud welding: the dimensions and tolerances for typical stud types, material specifications, mechanical characteristics (for example shear strength requirements), weldability considerations and, when required, conditions for evaluation of conformity. The standard also covers ordering information, coating and durability considerations for studs and ceramic ferrules. Amendment 1 (2021) supplies a targeted revision to the 2017 text.

Key topics and requirements

• Definitions, symbols and types of studs and corresponding ferrules (classification by form and thread type).
• Ordering information and required data to be supplied by purchaser (type, dimensions, material, surface condition, quantity, etc.).
• Dimensional requirements and tolerances for different stud forms (fully threaded, partially threaded, reduced shaft, etc.).
• Material specifications and mechanical characteristics, including shear strength and related tests.
• Weldability and guidance on use in arc stud welding processes.
• Requirements for coatings, durability and corrosion considerations where applicable.
• Manufacture, inspection, marking and designation requirements to ensure traceability and conformity.

These topics reflect the standard’s table of contents and clause structure as published and as implemented in national/adopted versions.

Typical use and users

Intended users include fastener and welding-consumable manufacturers, stud-welding equipment suppliers, fabrication and shipbuilding yards, structural and mechanical engineers, welding engineers and quality/inspection personnel. The standard is used to specify purchased studs and ferrules, to verify conformity during incoming inspection, and to support procurement and design decisions where arc stud welding is applied.

Related standards

ISO 13918 is commonly published/adopted in regional and national collections (for example EN ISO 13918:2018 and the published amendment A1:2021). Related documents include other ISO and EN welding standards and national implementation/adoption publications covering stud welding practices, testing and welding quality management. Earlier editions (for example the 2008 edition) were superseded by the 2017 edition and subsequent amendment.

FAQ

Q: What is this standard?

A: ISO 13918:2017 is an International Standard that specifies requirements for studs and ceramic ferrules used in arc stud welding; ISO 13918:2017/Amd 1:2021 is the published amendment to that edition.

Q: What does it cover?

A: It covers types and dimensions of studs and ferrules, material and mechanical property requirements (such as shear strength), weldability guidance, inspection, marking and ordering information; it may also include provisions for conformity assessment where required.

Q: Who typically uses it?

A: Manufacturers of studs and ceramic ferrules, stud welding equipment makers, fabricators (shipbuilding, construction, mechanical assembly), welding engineers, procurement and QA/QC personnel.

Q: Is it current or superseded?

A: As published, the 2017 edition is the current edition and was updated by Amendment 1 in September 2021. Users should verify whether any later revisions or replacements have been issued by checking official sources before specifying the standard for new procurements.

Q: Is it part of a series?

A: ISO 13918 is a standalone International Standard within ISO’s set of welding-related standards maintained by ISO/TC 44 (subcommittee SC 10 for quality in welding). It is commonly referenced alongside other welding process and consumable standards.
