Dimensions in millimetres Figure 1: This standard covers the following welding processes: Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from the publisher.

It is not intended that thicknesses or diameters should be measured precisely but rather the general philosophy behind the values given in tables 1 and 2 should be applied. The ability isp the welder to follow verbal or written instructions and testing of his skill are important isso in ensuring the quality of the welded product. 6906-3 macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required.

Special tests do not have any range of approval, outside the range of tolerances for the test carried out. Titanium and titanium alloys — Part 6: If the job knowledge test is carried out, it should be recorded on the welder’s certificate.

For all other welding positions, two root and two face bend test specimens shall be tested see figure 7 b. 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 following conditions shall apply: Fusion welded butt joints in steel plates up to 50 mm thick ISO International organizations, governmental and non-governmental, in liaison with ISO, also take part 96606-3 the work. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding.

The work of preparing International Standards is normally carried out through ISO technical committees. Aluminium and aluminium alloys — Part 3: A test is listed for each of the ranges of plate thickness and pipe wall thickness or pipe diameter as specified in tables 1 and 2. The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO When transverse bend testing is used, it shall be carried out in accordance with EN The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A.

When the filler metal is dissimilar to the parent metal group, an approval for that combination of parent metal group and filler metal is needed, except when permitted by table 4.

When welding parent metals from two different groups which do not give approval to each other according to table 4 see 6. The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6.

The approval of the examiner or test body shall be obtained. In some cases a welder approval test on a branch connection can be necessary. If any of these conditions are not fulfilled, the approval shall be revoked. Each change of the essential variables for the approval testing beyond the permitted ranges requires a new test and a new approval certificate. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

If any special tests are to be carried out because of the characteristics of particular welding processes, materials or dissimilar alloys, these shall be defined prior to carrying out the welder’s test.

The welder’s approval test shall be carried out on test pieces and is independent of the type of construction. 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.

Nickel and nickel alloys — Part 5: When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length. The number of fracture or transverse bend test specimens depends on the welding position.

Draft International Standards adopted by the Technical Committees are circulated to member bodies for voting. Owing to different training programmes in various countries, it is only proposed to standardize general objectives or categories of job knowledge.

ISO – Approval testing of welders — Fusion welding — Part 3: Copper and copper alloys

The term ”copper” stands for copper and weldable copper alloys. For any copper alloy not covered by any of the copper groups the welder shall carry out an approval test, which only approves for that copper.

This date can be different to the date of issue marked on the certificate. 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. The test weld can be used to approve a welding procedure and a welder provided that all the relevant requirements, e. The format of this Annex A of EN When fracture testing is used, it shall be carried out in accordance with EN
