If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN All relevant test conditions shall be recorded on the certificate. The acceptance requirements for imperfections found by test methods according to this standard shall, unless otherwise specified, be assessed following EN 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.

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. When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6. The range of approval for each type of test is given in the relevant sub-clauses and tables.

The type of shielding gas shall not be incorporated in the designation but shall be included in the welder’s approval test certificate see Annex A of Ios Material groups according to CR 5.

A minimum weld length of mm is required, but not more than three test pieces. For undated references the latest edition of the publication referred to applies.

In some cases a welder approval test on a branch connection can be necessary. The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.

The welding position H-L for pipes approves for all pipe angles in production work. When fracture testing is used, it shall be carried out in accordance with EN 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 butt welds.

When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length. The test pieces shall be marked with the identification of the examiner and the welder before welding starts. Dimensions of test piece for fillet weld s on plate Dimensions in millimetres Figure 3: The test weld can be used to approve a welding procedure and a welder provided that all the relevant requirements, e.

For welding position PA or PC, one root and one face bend test specimen shall be tested see figure 7 a. When transverse bend testing is used, one root bend test specimen and one face bend test specimen shall be tested in accordance with EN However, some countries can require that the welder undergoes a test of job knowledge.

Each test specimen shall be positioned for breaking as shown in figure 6b, and examined after fracture. These normative references are cited at the appropriate places in 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 isso prior to carrying out the welder’s test. 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.

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: One test piece per position. Fusion welded butt joints in steel plates up to 50 mm thick ISO If the welder fails any of the prescribed tests, no certificate shall be issued.

Prior to mechanical testing, backing strips, where used, shall be removed. 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.

In these tables the range of approval is indicated in the same horizontal line. This date can be different to the date of issue marked on the certificate. Copper and copper alloys — Part 4: Draft International Standards adopted by the Technical Committees are circulated to member bodies for voting.

Specified procedures shall be used for all destructive and non-destructive examinations. Preparation and fracture testing of test specimens for a butt weld 96606-3 plate 7. 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.

For all other welding positions, two root and two face bend test specimens shall be tested see figure 7 b. Preparation and fracture testing of test specimens for a fillet weld on plate 7. This 96606-3 covers approval testing of welders for work on semi-finished and finished products made from wrought, forged or cast material types listed in 5. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding.
