Welding Certification EN ISO 3834-2 Certificate

ISO 3834-2 standard certificate  is a system standard prepared by ISO to define appropriate quality requirements based on the fusion welding method of metals for manufacturers engaged in welded production.

ISO 3834-2 welded manufacturing qualification standard  is related to the quality of products in the manufacturing sector that may be affected by welding and welding-related processes.  The ISO 3834-2 welded manufacturing qualification standard  is a guiding standard to determine the required quality conditions for welded manufacturing carried out in the factory or on-site and the welding capability of the manufacturer to produce at the specified quality.

For welded fabrications, inspections should start at the design stage;

EN ISO 3834 Welded Manufacturing Compliance Quality Management System Certification

The quality of a product must be ensured during manufacturing, not through inspection. To produce products free of problems during manufacturing and service conditions, inspections must be carried out from material selection at the design stage to post-production inspections. For example, poor design can cause serious and costly problems in workshop or field applications. Incorrect material selection or unfavorable welding conditions may lead to cracks in welded joints. To ensure reliable and effective production, management needs to identify potential sources of problems and apply appropriate quality procedures. EN ISO 3834 defines measures that can be applied for different situations. These measures can be used in the following cases:

• In contract or tender cases; as a specification of welding quality requirements;
• By manufacturers to establish and maintain welding quality requirements;
• By third parties, customers, or organizations evaluating the welding quality performance of manufacturers.

The scope and importance of safety-critical products, the complexity of production, the range of use of manufactured products, the scope of possible metallurgical problems, and the scope of production defects that may affect product performance such as misalignment, distortion, or welding defects are documented under EN ISO 3834-2, EN ISO 3834-3, and EN ISO 3834-4 as comprehensive, standard, and basic quality requirements, respectively.
