Dimensions of test piece for a fillet weld on pipe 7. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. The specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN For a branch weld the range of approval is based on the diameter of the branch; f in cases where ios majority of production work is predominantly branch welding or involves a complex branch connection, the welder should receive special training.

This standard covers the following welding processes: Throughout the text of this standard, read ” The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: All relevant test conditions shall be recorded on the certificate.

Testing of skill to this standard depends on welding methods in which uniform rules and test conditions are complied with, and standard test pieces are used. A welders approval is valid for a period 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: Steels — Part 2: The following conditions shall apply: The welder’s approval test shall be carried out on test pieces and is 9066-3 of the type of construction.

One test piece per position. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Fusion welded butt joints in steel plates up to 50 mm thick ISO If any of these conditions are not fulfilled, the approval shall kso revoked. A minimum weld length of mm is required, but not more than three test pieces. The examiner or examining body shall verify compliance with the above conditions and sign the prolongation of the welder’s approval test jso.

Each test specimen shall be positioned for breaking as shown 960-63 figure 6b, and examined after fracture. Preparation and fracture testing of test specimens for a butt weld in plate 7. This date can be different to the date of issue marked on the certificate.

If the imperfections in the welder’s test piece exceed the permitted maximum specified, then the welder shall not be approved. Test specimen preparation, types of sio profiles and methods of fracture shall be in izo with EN In some cases a welder approval test on a branch connection can be necessary.

Titanium and titanium alloys — Part 6: This standard covers approval testing of welders for work on semi-finished and finished products made from wrought, forged or cast material types listed in 5.

Preparation and fracture testing of test specimens for a fillet weld on plate 7.

The test of job knowledge is limited to the matters related to the welding process used in the test. The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.

If it is established that failure is attributed to the welder’s lack of skill, the welder shall be regarded as incapable of complying with the requirements of this standard without further training before re-testing. This standard applies to the approval testing of welders for the fusion welding of copper.

Reference should also be made to the corresponding acceptance criteria for non-destructive examination. In general, a welder’s approval test shall involve depositing weld metal having a chemical composition compatible with any copper in the parent metal group s.

The format of this Annex A of EN The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO Nickel and nickel alloys — Part 5: For one root fracture or one root transverse bend or one side bend test specimen Position 2: 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.

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. Copper and copper alloys — Part 4: One root fracture test specimen and one face fracture test specimen shall be tested.

Special tests do not have any range of approval, outside the range of tolerances for the test carried out. The test pieces shall be marked with the identification of the examiner and the welder before welding starts.

The welder’s approval test certificate shall be issued at least in one of the official CEN languages English, French, German. For explanation of abbreviations used in the designation examples, see clause 4.

The work of preparing International Standards is normally carried out through ISO technical committees. However, it is possible for a welder to be approved for more than one welding process by a single test or by two separate approval tests to be used to cover a multi-process joint.

The acceptance requirements for imperfections found by test methods according to this standard shall, unless otherwise specified, be assessed following EN When welding parent metals from two different groups which do not give approval to each other according to table 4 see 6.

The approval of the examiner or test body shall be obtained. When radiographic testing is used, the inspection length of the weld see figure 7 a and 7 b in the 96063- piece shall be radiographed in the as-welded condition in accordance with EN using class B technique. 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. Specified procedures shall be used for all destructive and non-destructive examinations.
