European Standard EN 29692: 1993 has the Status of a DIN Standard.

National foreword This Standard has been has been published in accordance with a decision taken by CEN/BT to adopt, without alteration, International Standard ISO 9692 as a European Standard.

The responsible German body involved in its preparation was the Normenausschuß Schweißtechnik (Welding Standards Committee).

The dirnensions and the dimensional ranges given in this Standard are based on experience. In Order to make the scope as comprehensive as possible, wide tolerances have been specified for angles, gaps and root face thickness. The joint type shall be selected as a function of the materials employed, the welding Position and the welding process, subject to the weld being fully penetrated. This requires the selection of appropriate welding Parameters and, if necessary, root machining in the case of double-sided welding. The symbols for joint types are intended to facilitate comrnunication. If necessary, the designation may be completed by an additional indication of the required dimensions.

Foreword In 1992, CEN/BT decided to subrnit International Standard ISO 9692 : 1992 Metal-arc welding with covered electrode, gas-shielded rnetal-arc welding and gas welding; joint prepara-

to the Unique Acceptance Procedure in accordance with resolution BTS 2 C 48/1992.

The result was positive. This European Standard shall be given the Status of a national Standard, either by publication of an identical text or by endorsernent, and conflicting national Standards withdrawn, by August 1994 at the latest.

In accordance with the CENKENELEC Internat Regulations, the following countries are bound to irnplernent this European Standard: Austria, Belgiurn, Denrnark, Finland, France, Gerrnany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Endorsement notice The text of the International Standard ISO 9692 : 1992 was approved by CEN as a European Standard without any rnodification.

NOTE: Normative references to international publications are listed in annex ZA (normative).

lntroduction

This International Standard defines the Parameters characterizing the joint preparation and the collection of well-experienced values and shapes representing more design limits than manufacturing limits.

The requirements given in this International Standard have been com- piled on the basis of experience, and contain dimensions for types of joint preparation that are generally found to provide suitable welding conditions. However, the extended field of application makes it necess- ary to give a range of dimensions. The dimension ranges specified rep- resent design limits and are not tolerances for manufacturing purposes. Manufacturitlg limits depend, for instance, on welding process, parent metal, welding Position, quality level, etc. Therefore, the requirements given are more a recommendation than a specification. Because of the conimon character of this International Standard, the examples given cannot be regarded as the only Solution for the selection of a joint type.

Specific fields of application and manufacturing requiretnents (e.g. Pipeline construction) may be covered by selected ranges specified in other Standards adapted from this basic International Standard.

1 Scope

This International Standard pertains to types of joint preparation for metal-arc welding with covered electrode. gas-shielded metal-arc weldiny and gas welding on steel (See clauses 3 and 4).

It applies lo joint preparation for fully-penetrated butt welds, except in the case of some rec- ornrnended types of joint preparation (reference numbers 3 10A. 3.106 and 4.10.10Cj: if a butt weld is not possible or necessary. Special arrangenients need to be made. For not-fully-penetraled butt welds. types of joint preparation and dimensions differing from those specified in this Iniernational Standard may be stipulated.

The r o d yaps referred to in this International Stan- dard are thcxx gaps presented after tack welding. i f used.

Consideration should be given to alterlng the joint preparation details (where appropriate) to facilitate ternporary backing, "one-sided welding", etc.
