Welding It is a key technology in many industries – especially in the production of steel structures, pressure equipment, pipelines or individual machine parts. But how do you ensure that these welded structures are reliable, durable and safe – not just now, but for years to come? The answer to this is provided by the MSZ EN ISO 3834-2 standard, which is expected by an increasing number of customers, certifiers and general contractors. It is not just a “paper”, but a quality assurance system that regulates the welding activity carried out during production – from preparation to follow-up inspection. In this article, we present this standard in detail.
What is the MSZ EN ISO 3834-2 standard?
MSZ EN ISO 3834-2 is part of the internationally accepted welding quality management standard. The aim of the series of standards is to define: how to carry out the welding workto ensure that the final product is reliable. The marking “3834-2” covers the full range of quality requirements. This standard level is the most stringent and is intended for manufacturers who manufacture complex, safety-critical or durable welded structures – such as bridge or hall structures, pressure vessels or machine parts.
What is this standard good for?
The standard aims to ensure that every step of the welding process is controlled, documented and controllable. This is important not only for quality, but also from a legal, contractual and economic point of view:
- It provides safety: it prevents errors, recalls and accidents.
- Ensures compliance: in many cases, it is mandatory for EN 1090 or PED certification.
- It provides a competitive advantage: it can be a prerequisite for international work and large customers.
Who is ISO 3834-2 for?
The standard is recommended or mandatory for companies that:
- They manufacture steel structures (e.g. in case of CE certification according to EN 1090.
- They manufacture pressure equipment or boilers (PED directive).
- They carry out the construction of pipeline systems (e.g. chemical industry, energy industry).
- Metal parts of machines and equipment are welded in large numbers or with precision.
What does ISO 3834-2 require?
Compliance is not just about testing the final product – the standard covers the entire production process:
- Employment of qualified welders.
- Documentation of welding procedures (WPS, WPQR).
- Appointment of a welding coordinator (e.g. EWE, IWE).
- Performing tests (non-destructive tests, visual inspection).
- Traceability of materials.
- Controlled handling of deviations and errors.
- Keeping quality assurance documentation.
How to comply with the standard?
In most cases, compliance is done step by step, with the support of an external expert or consultant:
- Assessment, condition check.
- Preparation of documentation – WPSs, instructions, minutes.
- Personnel conditions – qualification of welders, coordinators.
- Internal audit – examination of processes and products.
- Certification – an audit by an independent organization.
What happens if there is no such certification?
Although it is not mandatory in all industries, its absence:
- You may be excluded from larger applications or international jobs.
- It can create distrust in customers.
- Increase scrap rates and repair costs.
- It may jeopardise the issuance of the CE marking (e.g. compliance is mandatory in the case of EN 1090).
