ISO 9692-2 pdf download – Welding and allied processes -Jointpreparation – Part 2: Submerged arc welding of steels.
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 refeiences
The following standards contain provisions which, through reference in this text, constitute provisions of this International Stanard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard 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.
ISO 2553: 1992, Welded, brazed and soldered joints — Symbolic representation on drawings.
ISO 3834-1: 1994, Quality requirements for welding — Fusion welding of metallic materials — Part 1: Guidelines for selection and use.
ISO 3834-2: 1994. Quality requirements for welding — Fusion welding of metallic materials — Part Z Comprehensive quality requirements.
ISO 3834.3: 1994, Quality requirements for welding — Fusion welding of metallic materials — Part 3: Standards quality requirements.
ISO 38344:1994, Quality requirements for welding — Fusion welding of metallic materials — Part 4: Elementary quality requirements.
4 Types of jdnt preparation
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 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.
