ISO 9692-2:1998 pdf download – Welding and allied processes – – Joint preparation一 Part 2: Submerged arc welding of steels.
This part of ISO 9692 applIes to typs of joint preparation let submerged arc welding with one wire electrode (process 121 accordIng to ISO 4063) on steel.
The part of ISO 9692 covers only the welding positions PA and PB according to ISO 6947. In case is used, special preparation will be necessary.
It applies to hilly 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.
It the root Is welded by a different arc welding process (see ISO 4063), he joint preparation according to ISO 9692 should be taken Into account.

3 Motedcds
Joint preparations recommended In this part of ISO 9692 are suetable for all types of weldable steel.
4 Types d )olnt peporahon
The recommended types of joint preparation and dimensions are specified in tables 1 and 2.
The root gaps referred to in this part of ISO 9892 are those gaps presented after tack welding. If used.
This pert of ISO 9892 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 th, relevant pail of ISO 38341 and the preparation as given in tables 1 arid 2. They shall be part of the welding procedure specIfication according to ISO
According to the applkation standard or agreement between contracting parties, it nay 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 ri ISO 2553; the third Indication, expressed by a letter, takes into account the variants of joint preparations.
