Executive summary Criteria for the selection of quality requirements for fusion welding of metallic materials.
Abstract This International Standard, a part of the ISO 3834 series, provides a general outline of ISO 3834 and criteria to be taken into account for the selection of the appropriate level of quality requirements for fusion welding of metallic materials, among the three levels specified in ISO 3834-2, ISO 3834-3 and ISO 3834-4. It applies to manufacturing, both in workshops and at field installation sites Quality requirements for fusion welding of metallic materials. Criteria for the selection of the appropriate level of quality requirements BS EN ISO 3834 provide the quality requirements for process control related to all welding processes (for each process separately or in combination as specified). The 5-part series of standards identifies measures that are applicable for different situations in workshops and/or on-site.
BS EN ISO 3834 is suitable for manufacturers to use on their own or in conjunction with ISO 9001:2000. The BS EN ISO 3834 series supersedes BS EN 729:1995 Parts 1-4.
To ensure sound and effective manufacturing, management needs to understand and appreciate the sources of potential trouble and to implement appropriate procedures for their control. The BS EN ISO 3834 series identifies measures that are applicable for different situations. Typically, they may be applied in the following circumstances:
in contractual situations: specification of welding quality requirements
by manufacturers: establishment and maintenance of welding quality requirements
by committees drafting manufacturing codes or application standards: specification of welding quality requirements
by organizations assessing welding quality performance, e.g. third p...
