Quality requirements for welding - Fusion welding of metallic materials - Part 4: Elementary quality requirements

Scope

This standard has been prepared such that: - it is independent of the type of welded construction to be manufactured; - it defines quality requirements for welding both in workshops and on site; - it provides guidance for describing a manufacturers capability to produce welded constructions to meet specified requirements; - it may also be used as a basis for assessing the manufacturer in respect to his welding capability. This standard is appropriate when demonstration of a manufacturers capability to produce welded construction, fulfilling specified quality requirements, are specified in one or more of the following: - a contract between involved parties; - an application standard; - a regulatory requirement. The requirements contained within this standard may be adopted in full or may be selectively deleted by the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control of welding in the following cases: - Case 1 To provide specific requirements for fusion welding in contracts which require the manufacturer to have a quality system other than EN 29001 or EN 29002 and where the documented welding control has a minor importance to the overall integrity of the final construction. - Case 2 To provide specific requirements for fusion welding as guidance to a manufacturer developing a quality system. - Case 3 To provide specific requirements for references in application standards which uses fusion welding as part of its requirements or in a contract between relevant parties.
