ISO 3834 - Quality requirements for fusion welding of metallic materials

In material joining process , fusion welding are widely used to manufacture many products. In some companies, they are the key feature of production. Products may range from simple to complex. Examples include Railway components , pressure vessels, domestic and agricultural equipment, cranes, bridges, transport vehicles , automobile , power sectors , Mining & defence and other fabrications

These processes exert a profound influence on the cost of manufacture and quality of the product. It is important, to ensure that these processes are carried out in the most effective way and appropriate control is exercised over all aspects of the operation. It is emphasised that ISO 3834 is not a quality management system standard replacing ISO 9001:2000. However, it can be a useful tool when ISO 9001:2000 is applied by the manufacturers. Specification of quality requirements for welding processes is important because the quality of these processes cannot be readily verified. Therefore, they are considered to be special processes as noted by ISO 9000:2000.

 Part 1: Criteria for the selection of the appropriate level of quality requirements
Part 2: Comprehensive quality requirements
Part 3: Standard quality requirements
Part 4: Elementary quality requirements
Part 5: Documents with which it is necessary to conform to claim conformity to
,,,the quality requirements of ISO 3834-2, ISO 3834-3 or ISO 3834-4

NOTE : A Technical Report ISO/TR 3834-6, Quality requirements for fusion welding of metallic materials — Part 6: Guidance on implementing ISO 3834 is being prepared.
