BS EN ISO – Approval testing of welders. Fusion welding. Copper and copper alloys
For a branch sio 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 isl training. In these tables the range of approval is indicated in the same horizontal line. The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A.
The test of job knowledge is limited to the matters related to the welding process used in the test.
BS EN ISO 9606-3:1999
If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN The term ”copper” stands for copper and weldable copper alloys. 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 9606- welds.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August A full explanation of these imperfections is given in EN This standard applies to the approval testing of welders for the fusion welding of copper.
When fracture testing is used, it shall be carried out in accordance with EN For explanation of abbreviations used in the designation examples, see clause 4. Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: The test piece can be sectioned by mechanical means discarding the first and the last 25 mm of the test piece at the end of the plates figures 5 and 6.
The following conditions shall apply: 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. Copper and copper alloys — Part 4: An interruption for a period no longer than six months is permitted; b There is no specific reason to question the welder’s skill and knowledge.

If the job knowledge test is carried out, it should be recorded on the welder’s certificate. Ios welder’s approval test certificate shall be issued at least in one of the official CEN languages English, French, German. The specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN Fusion welded butt joints in steel plates thicker than 50 mm and up to and including mm in thickness EN Each member body interested in a subject 9606–3 which a technical committee has been established has the right to be represented on that committee.
Material groups according to CR 5. The number of fracture or transverse bend test specimens depends on the welding position.
An approval test made on 96063- material groups gives approval for cast material and a mixture of cast and wrought material in the same material group see 5. For example in a case where approval is required for a single-side butt joint with the root to be welded by TIG without backing and to be filled by MIGthe welder can be approved by either of the following routes: The test pieces shall be welded in 9606-33 with the nominal angles of the positions according to EN ISO If any of these conditions are not fulfilled, 960-3 approval shall be revoked.
The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: If the circumference is less than mm, additional weld test pieces will be required.
The approval of the examiner or test body shall be obtained. When macroscopic 9606–3 is used, at least four test specimens shall be taken equally spaced in the inspection length.
The welder’s approval test shall be carried out on test pieces and is independent of the type of construction. The job knowledge indicated in this annex is only pitched at the most basic level.
A minimum weld length of mm is required, but not more than three test pieces. 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 Dimensions of test piece for a fillet weld on pipe 7.
During the approval test the welder should be required to show adequate practical experience and job knowledge test non mandatory of the welding processes, materials and safety requirements for which he is to be approved; information on these aspects is given in Annex A. Aluminium and aluminium alloys EN Throughout the text of this standard, read 96606-3 These normative 9066-3 are cited at the appropriate places isso the text and the publications are listed hereafter.
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. It does not cover fully mechanized and automatic processes see 5.
