ISO3834 international welding system certification is aimed at the special process of welding, requiring enterprises to combine design, process, production, and quality assurance to form a mature system together, in order to ensure the final quality requirements of the product. ISO3834 certification is based on ISO9001 and describes the welding quality requirements that should be included in the welding quality system, taking into account the actual application conditions of welding. ISO3834 welding certification is a mandatory quality control system requirement in certifications such as EN1090 for steel structures.

ISO3834 certification series standards

The ISO3834 series standards are divided into 5 parts:

ISO3834-1: Selection criteria for corresponding quality requirement levels

ISO3834-2: Complete Quality Requirements

ISO3834-3: General Quality Requirements

ISO3834-4: Basic Quality Requirements

ISO3834-5: Documents required to meet the quality requirements of each part

The selection of the corresponding level of quality requirements should be based on product standards, specifications, rules, or contracts. For the level of quality requirements, the corresponding parts of ISO3834, ISO3834-2, ISO3834-3, and ISO3834-4, should be selected.

When a manufacturer meets a certain quality level, it can be considered that it also meets all lower quality level requirements without further verification. For example, manufacturers that meet the complete quality requirements of ISO3834-2 also meet the general quality requirements of ISO3834-3 and the basic quality requirements of ISO3834-4.
