The ISO 3834 welding system standard is developed for the special welding process. This standard specifies the quality requirements for fusion welding of metal materials without any restrictions on the type of manufacture. It guarantees the quality of the welded products by the manufacturer in the welding activities and provides The basis for evaluating the manufacturer's welding capabilities was provided. ISO 3834 can be used in conjunction with ISO 9001 and is also required in certifications such as EN 1090 and EN 15085.
ISO 3834 parts, the first part is the selection criteria of the corresponding quality requirements level, that is, according to product standards, specifications, rules or contracts, for the level of quality requirements, select ISO3834-2 or ISO3834-4 for the complete quality requirements, ISO3834-3 is Basic quality requirements. If the manufacturer meets one of the specific grades, it can also be considered to meet other lower quality grade requirements. If it meets ISO3834-2, it also meets ISO 3834-3 and ISO 3834-4. The third part is the documents needed to meet the quality requirements of each part.
Audit requirements of ISO 3834:
