ISO 3834-2 sets out comprehensive quality requirements for the welding of metallic materials. Here you will find an overview of what this ISO standard entails, the requirements it sets out, and how it contributes to quality, traceability and control in the welding process.
What does ISO 3834-2 mean?
ISO 3834-2 – Quality assurance in welding
ISO 3834-2 is an international standard that ensures quality, traceability and control in welding. With the help of this welding standard, it is, for example, easier for companies to establish a framework for documentation, control and monitoring within industrial production.
What is ISO 3834-2?
ISO 3834-2 is part of the ISO 3834 series of standards, which covers quality requirements for welding processes. The standard is used in industrial manufacturing where welded structures must meet high standards of quality, safety and traceability.
The purpose of ISO 3834-2 is to ensure that the entire welding process is carried out in a controlled and documented manner. The standard is frequently applied in sectors such as the construction industry, infrastructure, the energy sector and other areas of advanced manufacturing where safety is of paramount importance, and covers everything from planning and the selection of materials to execution, inspection and post-inspection.
What does quality assurance in welding involve?
Quality assurance in welding involves ensuring that welded products meet defined requirements throughout the entire manufacturing process. As welding affects the strength and properties of the material, clear procedures, documentation and checks are required.
To achieve high-quality welding, companies that comply with ISO 3834-2 focus on, amongst other things:
- Documented welding procedures
- Controlled work processes
- Traceability of materials and components
- Competence assessment and welding certification for staff
- Quality controls and testing
- What are the requirements of ISO 3834-2?
- ISO 3834-2 sets out requirements for:
- That the welders/contractors hold welding certification and have undergone training
- That the welders have the necessary skills for the job
- Documentation and quality procedures
- Material traceability
- Inspections and testing procedures
- Handling of non-conformities
- Process control throughout the entire production process

The difference between ISO 3834-2 and other levels
ISO 3834 is divided into different levels depending on the welding requirements and complexity of the operation.
ISO 3834-2 covers the most comprehensive quality requirements and is used in advanced or safety-critical production.
ISO 3834-3 contains standardised quality requirements at an intermediate level.
ISO 3834-4 covers simpler and more basic quality requirements.
Which sectors may be covered by ISO 3834-2?
Welded structures for products subject to the highest standards of quality and safety may be covered by ISO 3834-2.
Examples of sectors where the standard is often a requirement:
- The construction and property sector
- The energy sector
- The aerospace industry
- The defence industry
- The pharmaceutical industry
- The food industry
- The automotive industry

ISO 3834-2 in sheet metal working and contract manufacturing
In sheet metal working and contract manufacturing, quality and traceability are crucial. Clear processes, the right expertise and documented working methods are required to ensure control over the entire production chain – something that ISO 3834-2 helps to facilitate.
Frequently asked questions about ISO 3834-2
Do I need to state that ISO 3834-2 applies to my product?
Yes, it’s important that we’re told this right from the start, as early as the quotation stage. We’ll put a specific procedure in place for the whole process.
What is ISO 3834-2?
ISO 3834-2 is an international standard that sets out comprehensive quality requirements for the welding of metallic materials in industrial manufacturing.
What does quality assurance in welding involve?
This means that the welding process is monitored, tested and documented to ensure the quality, strength and safety of the finished products.
Is ISO 3834-2 a certification?
No, ISO 3834-2 is a standard, but companies can undergo certification to demonstrate that they meet the standard’s requirements for quality assurance and process control.
What is the difference between ISO 3834-2 and ISO 3834-3 and -4?
ISO 3834-2 contains more comprehensive quality requirements, whilst ISO 3834-3 sets out more standardised requirements at an intermediate level. ISO 3834-4 sets out simple and basic requirements.
Which organisations need to be certified to the requirements of ISO 3834-2?
Companies that supply welded structures to, for example, the property sector, the energy sector, the aerospace industry, the defence sector, the medical technology sector and the food industry.
Why is traceability important in welding?
