ISO 3834

What is ISO 3834?

EN ISO 3834 standard defines quality requirements suitable for fusion welding processes of metallic materials, for welding both in workshops and on site. It is appropriate when demonstration of a manufacturer’s capability to produce welded constructions in accordance with specified criteria is required.

Why is ISO 3834 important to your organisation?

The assessment and certification of the welding capability of a manufacturer in accordance with the requirements of EN ISO 3834 Part 2, 3, or 4, can be provided as an integral part of ISO 9001 assessment and certification or as a stand alone assessment and certification of the welding operations and associated activities which influence the integrity of welds. 

Meaningful certification should provide the purchaser (and manufacturer) with a clear statement of the manufacturer’s capability to produce welded construction whether the welding controls are defined and assessed in conjunction with ISO 9001, or assessed as stand alone processes and related activities capable of producing welded construction to specified requirements. Assessment of conformity with the requirements of EN ISO 3834 should be of sufficient depth and rigour to confirm that the manufacturer has appropriate and acceptable welding capability and controls, and is capable of producing welded construction to the specified requirements. In conjunction with ISO 9001 standard the assessment should evaluate and confirm that the required EN ISO 3834 controls are exercised over all aspects of the welding operations appropriate to the manufacturer’s range of activities covered by the scope of QMS certification.
