2 EN ISO 3834-2 requirements<br />
2.1 Introduction<br />
EN ISO 3834-2 defines comprehensive quality requirements for fusion welding in workshops<br />
and/or on site. Therefore compliance to the requirements of this part should provide the best<br />
quality level achievable for the welding fabrication activities.<br />
2.2 Requirements review and technical review<br />
The Manufacturer shall review the contractual and any other requirements together with any<br />
technical data relevant to the welding fabrication activities, in order to verify that the work content is<br />
within its capability to perform, that sufficient resources are available to achieve delivery schedules<br />
and that documentation is clear and unambiguous. All information necessary to carry out the<br />
manufacturing operations shall be therefore available prior to the commencement of the work,<br />
otherwise it should be asked the purchaser 2 to provide all the necessary data.<br />
Moreover the Manufacturer shall identify any variation between the final contract and previous<br />
quotations and notify the purchaser of any programme, cost or engineering changes that may<br />
result.<br />
Within the contract review, particular attention should be given to the product standard to be used<br />
together with any supplementary requirements, and to statutory and regulatory requirements.<br />
As for the technical subjects to be considered, the following items should be considered in detail:<br />
a) parent material(s) specification and welded joint properties;<br />
b) quality and acceptance requirements for welds;<br />
c) location, accessibility and sequence of welds including accessibility for inspection and nondestructive<br />
testing;<br />
d) the specification of welding procedures, non-destructive testing procedures and heat treatment<br />
procedures;<br />
e) the approach to be used for the qualification of the welding procedures ;<br />
f) the qualification of the personnel;<br />
g) selection, identification and/or traceability (e.g. for materials, welds);<br />
