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 production plants and on site;

- it provides guidance for describing a manufacturers capability to produce welded constructions to meet specified requirements;

- it can 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 or a sub-contractors capabity to produce welded constructions, 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 can be adopted in full or can 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 resistance welding in contracts which require the manufacturer or sub-contractor to have a quality system other than EN ISO 9001 or EN ISO 9002 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 resistance welding as guidance to a manufacturer or sub-contractor developing a quality system.

-Case 3

To provide specific requirements for references in application standards which use resistance welding as part of their requirements or in a contract between relevant parties.

For general guidelines for selection and use see EN 729-1 with the exception of Annex B and under consideration that for resistance welding only comprehensive and elementary requirements are specified. Annex A in this standard applies for resistance welding.
