Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents . ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 7, Representation and terms, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 9692-2:1998), of which it constitutes a minor revision. The changes are as follows:

• Clause 1, fourth paragraph revised and moved to the Introduction;
• ISO 2553, ISO 6947 and ISO 9692-1 moved from Clause 2 to the Bibliography;
• alignment in Clause 5 of the note explaining the reference numbers in Tables 1 and 2 with the corresponding text in ISO 9692-3;
• modification of the reference numbers in Tables 1 and 2 in accordance with the latest version of ISO 2553 and reordering of the lines of the tables in ascending order of the new reference numbers.

A list of all parts in the ISO 9692 series can be found on the ISO website.

Introduction

This document is intended to be used alongside ISO 9692-1. It follows similar rules and the same layout. Therefore, the introduction given in ISO 9692-1 also applies.

ISO 9692-1 specifies joint preparations for other arc welding processes (see ISO 4063), which are applicable when the root is not welded by submerged arc welding.

1 Scope

This document applies to types of joint preparation for submerged arc welding with one wire electrode (process 121 according to ISO 4063) on steel.

This document covers only the welding positions PA and PB according to ISO 6947. If PC is used, special preparation is necessary.

This document applies to fully penetrated welds. For partly penetrated welds, types of joint preparation, shapes and dimensions can differ from the listed proposals if they are specified in the relevant application standard or agreed by the parties concerned.
