ISO 3834

Evaluate the conformity of the welded products

ISO 3834 is the standard dedicated to welding and defines useful guidelines for welding activities, both for those who perform them and for those who evaluate them.

The ISO 3834 standard is a process standard that addresses, regardless of the product, all the activities related to a specific production process, and also a transversal standard as it is applicable to different products and sectors.

ISO 3834 is designed to be used for both fabrication (including any type of fusion welded construction) and evaluation. It is used by internal and external organizations (clients, construction management), to evaluate the ability of a "manufacturer of welded products" in satisfying the customer's requirements, regulations or their own requirements.

The ISO 3834 standard (part 2a-3a-4a) is applicable both to companies operating in the EA 17-18-22a-28-29b sectors on a "voluntary" basis (eg Dir.PED 97/23 / CE, Dir.Macchine 2006/42 / CE etc.), whose product is made by making permanent joints / welding of metal materials (products / welded metal structures) both in the production workshop and in external sites and also in combination with each other (production workshop + external sites), and at companies operating in the EA 17/28 sector under the "mandatory" regime (ref. DM 14-01-2008 / Technical Standards for Construction, and from 01-07-2014 according to EN 1090-1 for CE marking according to Regulation (EU) 305/2011.

Furthermore, with the new European regulatory scenario that imposes the CE marking for structural metal products according to EN 1090-1, compliance with ISO 3834 becomes mandatory and preparatory for all companies that produce structural metal products assembled by means of welded joints.

The complexity of this process requires the total involvement of all company structures and, in order to allow the good quality of the welds, it is essential to plan, implement and qualify the processes, the welders and control the products adequately and comprehensively.

The more companies in the sector act in harmony with the applicable standards (ISO 9001 and ISO3834), international codes, technical specifications, which require the observance of certain safety and process requirements, the more reliable and demonstrable the quality of production processes and products will be, but for this it is necessary that all the personnel involved, both managerial , coordination and operational is made aware of this.

The standard has been structured in such a way that it can be used for the manufacture, both in the workshop and on site, of any type of fusion welded construction.

We point out, in particular, that the certifications EN ISO 9001 and EN ISO 3834 are mandatory for the application of the new Technical Standards for Construction issued with the DM January 14, 2008.
