Contribution of welding processes product certification

Integration of ISO 3834:2005 with a product standard

ISO 3834:2005 & Steel structure

Production of steel structures - supplements general terminology to the EN standard and explanation of terms from the sphere of documentation and products (FPC) - specifies requirements for capability of manufacturers, assembly, surface finish - adds the topics of management, verification inspections, maintenance, refurbishment and disposal of structures.

ISO 3834:2005 & EN 1090-7

EN 1090-2: Production of steel and aluminium structures, technical requirements for steel structures.

ISO 3834:2005 & EN 1090-8

ČSN EN 1090-3: Production of steel and aluminium structures, technical requirements for aluminium structures.

ISO 3834:2005 & EN 15085-7

Welding of railway vehicles; EN 15085-2 Railway applications - Welding of railway vehicles and their parts - Part 2 - Requirements for quality and manufacturer’s certification within welding.

ISO 3834 and marketing

Will the welding production management system help marketing?

It is the other way round, marketing must establish requirements concerning the quality management system within welding processes. The client s opinion about the quality of welding operations is important. There is a number of fields where the supplier can only meet the requirements made by product standards, however it is necessary to take into account that according to the client the quality is not only the utility properties of a product, however the client assesses also the quality of related logistic, production supporting and production processes as well as other ways of communication in connection with the final provision of the order. In a number of fields the standardised quality requirements do not exist or the standards fail to respond to modern trends. The welding production management system in accordance with ISO 3834:2005 is a key factor as a company management system owing to which the management can adopt proper strategic decisions about production innovation or for instance about the changes in processes in order to improve quality.

ISO 3834 & EN 1090

The growth of the applicability of steel structures in construction increases the demand not only quality but also on the safety performance of welding work. Construction industry (steel building structures, bridge structures, etc.) is an area where manufacturers face significant demands on safety and quality of welded joints, which is necessary to declare the quality management system certification in welding processes according to ISO 3834:2005 & EN 1090:2007 .

International validity

As a basic condition for establishing the requirements for a product we always choose the most internationally recognized standards and regulations, which gradually extend its accreditation to cover the widest requirements of its customers. We can provide special certificates as required by countries that have established special requirements for a particular product
