DIN EN ISO 3834 and DIN EN 1090 – connection
A welding company certified according to DIN EN 1090 is obliged to operate quality assurance in the sense of DIN EN 3834 and, if necessary, to document it. DIN EN 1090 contains a recommendation for selecting the appropriate level. This is based on the required design classes (EXC) of the product to be manufactured.
- EXC 1 -> ISO 3834-4 -> Simple supporting structures on private land
- EXC 2 -> ISO 3834-3 -> Structures that cannot be classified in EXC 1, 3 or 4
- EXC 3-4 -> ISO 3834-2 -> Complex structures and those on public land
Possibility of certification according to DIN EN ISO 3834
Various certification companies offer an audit and issuance of a certificate in connection with DIN EN ISO 3834ff. However, there are no legal requirements for welding companies. Certification is therefore absolutely voluntary for everyone.
However, advantages can arise for supplier companies if customers prefer companies with such certificates. The supplier has already proven that it can work according to defined quality standards. The customer can count on a higher quality standard because a QM system adapted to the company is established. Furthermore, there are also industrial customers who order exclusively from manufacturers with successful 3834 auditing. Thus, certification can be worthwhile and should be considered on a case-by-case basis.
Components of the standard
The EN ISO 3834ff standard is divided into five parts and deals with quality requirements in welding technology.
- In order to be able to select a suitable level of the documentation scope (level 2-4, two is the highest level, 4 the smallest), EN ISO 3834-1 is provided.
- The following sheets EN ISO 3834 2-4 define quality requirements and documentation obligations. The second level describes comprehensive requirements, the third standard requirements and the fourth elementary requirements. Thus, there is no “first” level.
- The sheet EN ISO 3834-5 describes documents whose requirements must be verified for the respective level.
