The examiner or examining body shall verify compliance with the above conditions and sign the prolongation of the welder’s approval test certificate. Fusion welded butt joints in steel plates up to 50 mm thick ISO Aluminium and aluminium alloys EN The specimen preparation, types of notch profiles and methods of fracture shall 9606–3 in accordance with 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.
In sio cases a welder approval test on a branch connection can be necessary. Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: Each test specimen shall be positioned for breaking as shown in figure 6b, and examined after fracture. If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN ISO consists of the following iwo, under the general title Approval testing of welders — Fusion welding: When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6.
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. Each change of the essential variables for the approval testing 960-63 the permitted ranges requires a new test and a new approval certificate.
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.
One root fracture test specimen and one face iiso test specimen shall be tested. The format of this Annex A of EN The acceptance requirements for imperfections found by test methods according to this standard shall, unless otherwise specified, be assessed following EN 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publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August The test weld can be lso to approve a welding procedure and a welder provided that all the relevant requirements, e.
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.
Owing 906-3 different training programmes in various countries, it is only proposed to standardize general objectives or categories of job knowledge.
However, some countries can require that the welder undergoes a test of job knowledge. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding.
The macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required. This date can be different to the date of issue marked on the certificate.
BS EN ISO – Approval testing of welders. Fusion welding. Copper and copper alloys
This standard applies to the approval testing of welders for the fusion welding of copper. A welder is approved if the imperfections in the test piece are within the specified limits of level B in ENexcept for imperfection types as follows: The number of fracture or transverse bend test specimens depends on the welding position.
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 The work of preparing International Standards is normally carried out through ISO technical committees.
The following conditions shall apply: 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 approval testing of welders for work on 9660-3 and finished 9606-33 made from wrought, forged or cast material types listed in 5. Material groups according to CR 5.
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.
If the welder fails any of the prescribed tests, no certificate shall be issued.
