Authored by Andrew Gillings

Last Updated: 17th June 2026

Like in many industries, there are ISOs, or international standards, available within stud welding to indicate that a company or product is certified as high quality and reliable. If you work within the stud welding industry, understanding these standards and working towards certification could help you to improve and expand your business. It also ensures that you’re following proper safety and quality codes.

Read more about stud welding standards with Taylor Stud Welding, the UK’s only designer, manufacturer and supplier of stud welding machines and equipment.

Welding Codes

Internationally, there are many welding codes. Some are specific to certain countries or regions, while others are international. These codes are designed to help ensure that welding machinery is of the highest quality and people involved in the process, from manufacture to use, are safe and know best practises.

Codes and standards help to facilitate trade between different companies, even internationally. They act as a baseline measure and assurance of quality so companies feel confident when buying a product or service.

Stud Welding Standards

The BSI (British Standards Institution) is the UK government’s appointed standards body, producing technical standards for a wide range of products and services. The standards and documents listed below are specific to Britain and all apply to welding, albeit a range of different types of welding.

ISO 3834 – Quality requirements for fusion welding of metallic materials. This specification lays out the levels of quality requirements for each level of quality and their specific requirements

ISO 4063 – Welding and allied processes – Nomenclature of processes and reference numbers

ISO 6947 – Welding positions

ISO 9606 – Qualification testing of welders

ISO 13918 – Welding – Studs and ceramic ferrules for arc stud welding. This covers the dimensional requirements and associated specifications for the studs used in stud welding processes.

ISO 14555 – Welding – Arc stud welding of metallic materials. This is an important standard in stud welding. It covers the requirements for the qualification of welding personnel and welding procedures for the mechanical fastening of accessories using stud welding processes.

ISO/TR 15608 – Welding – Guidelines for a metallic materials grouping system

International Standards

There are over 18500 international standards, or ISOs, with over 1000 new ones published each year. Even specifically relating to welding, there are numerous different standards that could be useful to different companies according to the type of welding and what its purpose is. For example, ISO 14112 specifically related to small, gas welding equipment kits.

The international standards that we’re most interested in at Taylor Studwelding are ISO 13918 and ISO 14555 because these relate directly to stud welding.

ISO 13918

This is a welding standard that relates specifically to studs and ceramic ferrules used in arc stud welding.

The most recent edition was released in 2017, replacing ISO 13918:2008, with various changes from the earlier edition (which are all listed on the ISO 13918 website). This standard will soon be replaced with ISO/AWI 13918 which is currently under development.

The ISO 13918 specifies that it can be used in all fields of metal working, but is particularly useful for those who work with arc stud welding and related products and services.

It covers the requirements of studs and ceramic ferrules that are used for arc stud welding, including the dimensions, materials and mechanical properties of the specific kinds of studs and ceramic ferrules.

It covers a wide range of different arc welding studs including those for drawn arc stud welding, short cycle and welding with tip ignition. This includes:

• Fully-threaded studs

• Virtually fully-threaded studs

• Partially threaded studs

• Threaded studs with reduced shaft

• Insulation pin/nails

• Studs with internal thread

• Shear connectors

• Threaded studs with flange

• Unthreaded studs

The ISO 13918 helps companies, businesses and manufacturers to better understand the standard quality for arc stud welding so as to provide a higher quality product or service.

Taylor Stud Welding have a huge collection of weld studs for arc stud welding which comply with and meet the international standards set in ISO 13918. We pride ourselves on being industry leaders in stud welding, providing the highest quality stud welding equipment and machines.

ISO 14555 

This standard is appropriate for manufacturers to prove competence in their production of weld construction to a specified standard. The standard covers specific requirements related to stud welding, focusing on production using arc stud welding of metallic materials under both static and fatigue loading conditions. The ISO 14555 criteria includes:

• Welding expertise

• Quality standards

• Welding procedure specifications

• Qualification of welding procedures

• Operating qualification testing

• Assessment of production welds.

ISO 14555:2025 is the current international standard for arc stud welding of metallic materials, replacing ISO 14555:2017. It applies to arc stud welding applications subject to static and fatigue loading and sets out requirements relating to welding knowledge, quality requirements, welding procedure specifications, welding procedure qualification, operator qualification testing and production weld testing.

The 2025 edition is a technically revised fifth edition. Publicly available ISO preview information confirms that normative references and bibliography have been updated, so manufacturers, fabricators and specifiers should ensure they are working to the latest edition when referencing ISO 14555 in contracts, project specifications or quality documentation.

At Taylor Studwelding, ISO 14555 is especially relevant when supporting customers with standards-led stud welding applications, including process setup, equipment selection, operator considerations and production weld quality.

How Taylor Studwelding Applies Stud Welding Standards in Practice

At Taylor Studwelding, standards are not treated as a paperwork exercise. They influence how we design, manufacture, test and support our stud welding equipment and accessories.

In practical terms, this includes:

• Supplying weld studs and ceramic ferrules that meet relevant dimensional and material requirements

• Advising customers on equipment and stud selection for their application

• Supporting customers with process setup, weld quality and repeatability

• Testing equipment before dispatch

• Maintaining quality management systems that support consistent manufacturing output

This practical application of standards helps customers achieve reliable weld performance across sectors such as construction, fabrication, infrastructure, shipbuilding, energy and industrial manufacturing. From our UK manufacturing base in Dewsbury, we support customers across construction, fabrication, energy, infrastructure, shipbuilding and industrial manufacturing. 

Taylor Studwelding’s Practical Checklist for Standards-Led Stud Welding

When supporting customers with stud welding applications, our team considers:

1. Application requirements — what the stud is fastening, loading conditions and operating environment.

2. Material compatibility — parent material, stud material and surface condition.

3. Stud and ferrule specification — diameter, length, thread type, material and relevant standard.

4. Equipment selection — drawn arc, capacitor discharge or short-cycle stud welding depending on the application.

5. Weld procedure control — settings, repeatability and operator competence.

6. Testing and inspection — visual checks, bend testing, torque testing or project-specific assessment where required.

How to Specify Stud Welding Equipment for Regulated Projects

When stud welding is used in regulated, safety-critical or standards-led environments, equipment specification should go beyond machine capacity alone. Engineers, buyers and project teams need to consider the full welding system, including the stud type, base material, ferrule, welding process, operator competence, testing requirements and relevant project standards.

Note: Standards requirements can vary depending on the project, sector, material, country and contractual specification. Taylor Studwelding can advise on stud welding equipment and consumables, but customers should always confirm final compliance requirements with the relevant project engineer, inspector, notified body or standards authority.

Common Standards Questions We Hear from Customers 

Do I need ISO 13918 or ISO 14555 compliance?

ISO 13918 is most relevant when specifying weld studs and ceramic ferrules, while ISO 14555 is more focused on the stud welding process, procedure qualification, operator qualification and production weld assessment. ISO accreditations and certifications are mandatory by law. They are voluntary standards designed to help businesses improve processes across quality, safety, and efficiency. Whilst they are not mandatory by law, they are often perceived as a commercial expectation to showcase high standards within a manufacturing business.

Can Taylor help me choose the right stud for a compliant application?

Our team can advise on stud type, material, diameter, equipment choice and process suitability based on the application. Just get in touch with our team for expert support or take a look at our equipment comparison guide.

Do standards apply to both equipment and consumables?

Yes, but in different ways. Some standards relate to the welding process and procedure, while others define requirements for studs, ferrules, materials and quality systems.
