ISO 9692-2:1998 pdf free download.Welding and allied processes — Joint preparation — Part 2: Submerged arc welding of steels.
This part of ISO 9692 applies to types of joint preparation for submerged arc welding with one wire electrode (process 121 according to ISO 4063) on steel.
Thee part of ISO 9692 covers only the welding positions PA and PB according to ISO 6947. In case PC Is used, special preparation will be necessary.
It applies to fully penetrated welds. For partly penetrated welds, types of joint preparation, shapes and dimensions may differ from the listed proposals if they are specified in the relevant application standard or agreed by parties concerned.
If the root is welded by a different arc welding process (see ISO 4063), the joint preparation according to ISO 9692 should be taken into account.
2 NormatIve re(ences
The following standards contain provisions which, through reference in this text, constitute provisions of ISO 9692-2. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on ISO 9692-2 are encouraged to investigate the possiblity of applying the most recent editions of the standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards.

3 MaterIals
Joint preparations recommended in this part of ISO 9692 are suitable for all types of weldable steel.
4 Types of boint preparation
The recommended types of joint preparation and dimensions are spec ified in tables 1 and 2.
The root gaps referred to in this part of ISO 9692 are those gaps presented after tack welding, if used.
This part of ISO 9692 gives no dimensions or type of possibly used backing materials. Root runs may also be used as backing. They may influence the quality requirements for welding (according to the relevant part of ISO 3834) and the preparation as given in tables 1 and 2. They shall be part of the welding procedure specification according to ISO
9956-2.
According to the application standard or agreement between contracting parties, it may be necessary to grind the slag before welding the next run.
NOTE — The reference numbers have been determined in accordance with the following scheme:
The first digit corresponds to the number of the table: the second digit or numerical group corresponds to the number in ISO 2553; the third indication, expressed by a letter, takes into account the variants of joint preparations.
