Quality marks and certification
KWALITEIT en CERTIFICERING
Our products and parts find their way to diverse sectors, each with its own requirements for quality, safety, and traceability. Through certified processes, qualified professionals, and meticulous quality assurance, we ensure that our production meets these requirements.
Quality as part of the process
Quality is not created solely during the final inspection. At Delwi Groenink, quality assurance is part of the entire manufacturing process.
From materials and production to welding, coating, and assembly: we work according to established procedures and relevant standards. This enables us to produce for clients in diverse sectors where high demands are placed on quality and reliability.
Certifications
EN ISO 3834-2:2021
Delwi Groenink is certified according to EN ISO 3834-2:2021, the standard for comprehensive quality requirements in the fusion welding of metals.
The certification relates to welding processes 135 and 138 and includes materials from S235 through S355 and S690QL, among others, within the material groups indicated on the certificate. The certification also sets requirements regarding welding coordination, procedures, and quality assurance, among other things.
With this, the quality of our welding process is not only visible in the end product but also demonstrably guaranteed throughout the production process. The internal machine documentation also confirms certified welding according to EN ISO 3834-2 and the same material and process groups.
NEN-EN 10204
Delwi Groenink holds internal authorization to re-certify materials according to EN 10204.
This demonstrates that functional traceability exists within Delwi for the internal re-certification of materials, while maintaining the relationship with the original inspection documents.
The certification includes the management and re-certification of material and inspection documents of types 2.1, 2.2, 3.1, and 3.2, within the conditions of the certificate.
The procedure is subject to periodic inspection by TÜV NORD.
