The practical test is the examination of job knowledge see Annex A shall be designated by ”Accepted” or ”Not tested”. 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publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August The welding of any one material in a group confers approval on the welder for the welding of all other materials within the same group.

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. Reference should also be made to the corresponding acceptance criteria for non-destructive examination.

Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: Test methods Test method Butt weld plate Butt kso pipe Fillet weld Visual mandatory mandatory mandatory Radiography 966-3 mandatory not mandatory Bend mandatory 1 izo 1 not mandatory Fracture mandatory 1 mandatory 1 mandatory 2 Macroscopic not mandatory not mandatory not mandatory 2 Penetrant not mandatory not mandatory not mandatory 1 Bend or fracture test shall be used, but not both test methods.

This date can be different to the date of issue marked on the certificate. The welder’s approval test shall be carried out on test pieces and is independent of the type of construction. 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.


For explanation of abbreviations used in the designation examples, see clause 4. When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6.

If any of these conditions are not fulfilled, the approval shall be revoked. This standard applies to the approval testing of welders for the fusion welding of copper. The number of fracture or transverse bend test specimens depends on the welding position.

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 job knowledge indicated in this annex is only pitched at the most basic level. The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO For all other welding positions, two root and two face bend test specimens shall be tested iiso figure 7 b.

The test of job knowledge is limited to the matters related to the welding process used in the test.

When welding parent 9066-3 from two different groups which do not give approval to each other according to table 4 see 6. The specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN However, some countries can require that the welder undergoes a test of job knowledge. A isl is listed for each of the ranges of plate thickness and pipe wall thickness or pipe diameter as specified in tables 1 and 2.

Prior to mechanical testing, backing strips, where used, shall be removed. One test piece per position. Aluminium and aluminium alloys — Part 3: Preparation and fracture testing of test specimens for a fillet weld on plate 7. Nickel and nickel alloys — Part 5: Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.


One root fracture test specimen and ios face fracture test specimen shall be tested.

In these tables the range of approval is indicated in the same horizontal line. 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.

Fusion welded butt joints in steel plates thicker than 50 mm and up to and including mm in thickness EN A full explanation of these imperfections is given in EN The examiner or examining body can stop the test if the welding conditions are not correct or if it appears that the welder does not have the technical competence to comply to the requirements of this standard, e.

The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A.

If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN 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.

Titanium and titanium alloys — Part 6: An approval 6906-3 made on wrought material 96066-3 gives approval for cast material and a mixture of cast and wrought material in the same material group see 5.
