The ISO 3834-2 standard certificate is a system standard prepared by ISO in order to determine the appropriate quality conditions based on the melting welding method of metals.

The ISO 3834-2 sourced manufacturing qualification standard is related to the quality of the product that may be affected by welding and welding-related processes that can be applied in the production sector. The foundation of the ISO 3834-2 welded manufacturing qualification standard is a guiding standard for determining the quality conditions required for welded manufacturing in the factory or in the field and the welding ability of the manufacturer to produce at the specified quality.

For welded fabrications, the controls are starting from the design phase;

En ISO 3834 Welded Manufacturing Compliance Quality Management System Certification

The quality of a product must be ensured during manufacture, not by inspection. For products that are free from problems in production and service conditions, controls should be provided from material selection during the design phase to post-manufacturing inspections. For example, poor design can create serious and costly problems in workshop or field application. Incorrect material selection or adverse welding conditions may cause cracks in welded joints. To ensure sound and effective production, management needs to know possible sources of problems and to implement appropriate quality procedures. EN ISO 3834 determines the measurements that can be taken for different situations. These measures are

  • In contract or tender situations; as the specification of the welding quality conditions;
  • By the manufacturers, for the establishment and maintenance of quality welding conditions;
  • It can be used by organizations that evaluate weld quality performance for third parties, customers or manufacturers.

The scope and importance of safety-critical products is documented in terms of the complexity of manufacturing, the range of use of the products produced, the scope of metallurgical problems that may occur, the scope of manufacturing defects that will affect the product performance such as misalignment, distortion or welding defects at quality levels such as EN ISO 3834-2, EN ISO 3834-3 and EN ISO 3834-4.
