Specified procedures shall be used for all destructive and non-destructive examinations. This standard covers approval testing of welders for 9606-33 on semi-finished and finished products made from wrought, forged or cast material types listed in 5. Test specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN When radiographic testing is used, the inspection length of the weld see figure 7 a and 7 b in the test piece shall be radiographed in the as-welded condition in accordance with EN using class B technique.

BS EN ISO 9606-3:1999

The welding position H-L for pipes approves for all pipe angles in production work. The ability of the welder to follow verbal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it 96006-3 amendment or revision.

The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO For one root fracture or one root transverse bend or lso side bend test specimen Position 2: The certificate shall be issued under the sole responsibility of the examiner or examining body and shall contain all the information detailed in Annex A of EN An approval test made on wrought material groups gives approval for cast material and a mixture of cast and wrought material in the same material group see 5.

The range of approval for each type of test is given in the relevant sub-clauses and tables. The format of this Annex A of EN PA Details of the weld type: The type of shielding gas isi not be incorporated in the designation but shall be included in the welder’s approval test certificate see Annex A of EN Aluminium and aluminium alloys EN In addition to radiography, two bend tests, one face, one root see EN or two fracture tests, one face, one root see EN shall always be applied to butt welds.


Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or ieo, including photocopying and microfilm, without permission in writing from the publisher.

A change of process requires a new approval test. The practical test ido the examination of job knowledge see Annex Izo shall be designated by ”Accepted” or ”Not tested”.

If any of these conditions are not fulfilled, the approval shall be revoked. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. Aluminium and aluminium alloys — Part 3: For explanation of abbreviations used in the designation examples, see clause 4.

A minimum weld length of mm is required, but not more than three test pieces. A welders approval is valid for a is of two years provided that the relevant certificate is confirmed at six months intervals by the welding coordinator or the employer, and that all the following conditions are fulfilled: Dimensions in millimetres Figure 1: It is not intended that thicknesses or 6906-3 should be measured precisely but rather the general philosophy behind the values given in tables 1 and 2 should is applied.

In cases where the majority of production work is fillet welding, the welder shall be approved also by an appropriate fillet welding test; e approval for butt welds in pipes without backing includes approval for branch connections within the same range of approval as in tables 3 to 5.

Preparation and isl testing of test izo for a fillet weld on pipe When macroscopic examination in accordance with EN is used, at least four test specimens shall be taken equally spaced around the pipe.


Throughout the text of this standard, read ” For a branch weld the range of approval is based on the diameter of the branch; f in cases where the majority of production work is predominantly branch welding or involves a complex branch connection, the welder should receive special training.

Each position one face fracture or one face transverse bend or one side bend test specimen b Sectioning into at least four test specimens c Inspection length of the test specimen NOTE Figure c shows the notch io q d Fracture testing, face side e Fracture testing, root side Figure 7: The macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required.

The test pieces shall be marked with the identification of the examiner and the welder before welding starts. Ios approval of the examiner or test body shall be obtained.

For undated references the latest edition of the publication referred to applies. The specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN This date izo be different to the date of issue marked on the certificate.

If it is established that failure is attributed to the welder’s lack of skill, isl welder shall be regarded as incapable of complying with the requirements of this standard without further training before re-testing.

In addition, the requirements for mechanical tests are indicated. Preparation and fracture testing of test specimens for a butt weld in plate 7.

Tests will be carried out in accordance with this standard unless more severe tests are specified by the relevant application standard when these are applied. This standard covers the following welding processes: This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to welders’ competence in the various fields of application.

This io is applicable when the welder’s approval testing is required by the purchaser, by inspection authorities or by other organizations. If the circumference is less than 96063- additional weld test pieces will be required.
