What does ISO 3834-2 certification mean:
ISO 3834 is the quality assurance standard for metal fusion welding. This standard consists of three levels and Ommeren Metaaltechniek BV is certified for the most extensive level: ISO 3834-2.
The certification means that we work with qualified welders according to approved procedures under the supervision of our welding coordinator. ISO 3834-2 is a quality certification for our complete welding organisation from order receipt, non-destructive testing, welding method description (WPS (Welding Procedure Specification) and WMD (Welding Method Description)), welding method qualification (WPQ (Welder Performance Qualification) and WMQ (Welding Method Qualification)), welding consumable management, welding equipment maintenance, training and qualification of welders, visual weld inspection, material traceability through to product delivery.  The certification provides assurance regarding the quality of your product.
Reasons for ISO 3834-2:
Ommeren Metaaltechniek BV has ample experience with systems for which the objective is to assure the quality of the organisation and our products and services. Ommeren Metaaltechniek BV is, therefore, ISO 9001-2015 certified. This standard, however, cannot be applied to welding technology activities. The quality of the welding can only be assessed after it has been completed. Welding is a "special process".
The International Standardisation Organisation (ISO) and the European Committee for Standardisation (CEN, French: Comité Européen de Normalisation) worked in partnership to develop a special system of standards to create a quality assurance system for welding. The developed standard is the ISO 3834-2. ISO 3824-2 is the most extensive certification for welding technology activities.
The ISO 3834-2 standard allows the organisation to implement a quality assurance system for all types of welding activities through procedures, work instructions and checks. The Ommeren Metaaltechniek BV quality system in accordance with ISO 3834-2 is described in the Ommeren Metaaltechniek BV welding quality manual.
