Test specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN Dimensions of test piece for fillet weld s on plate Dimensions in millimetres Figure 3: A welders approval is ido 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 96063- following conditions are fulfilled: If any of these conditions are not fulfilled, the approval shall be revoked.
Preparation and fracture testing of test specimens for a fillet weld on plate 7.
However, some countries can require that the welder undergoes a test of job knowledge. If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN Fusion welded butt joints in steel plates thicker than 50 mm and up to and including mm in thickness EN These normative references are cited at the appropriate places in the text and the publications are listed hereafter.
The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A. Specified procedures shall be used for all destructive and non-destructive examinations.

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. Each change of the essential variables for the approval testing beyond the permitted ranges requires a new test and a new approval certificate.
The range of approval for each type of test is given in the relevant sub-clauses and tables. 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 96606-3 3 to 5. The welding position H-L for pipes approves for io pipe angles in production work.
The test pieces shall ios marked with the identification of the examiner and the welder before welding starts. It does not cover fully mechanized and automatic processes see 5.
This date can be different to the date of issue marked on the certificate. 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.

All relevant test conditions shall be recorded on the certificate. Each position one face fracture or one face transverse bend or one side bend test specimen b Sectioning into at least four test specimens c Inspection length of the test specimen NOTE Iwo c shows the notch profile q d Fracture testing, face side e Fracture testing, root side Figure 7: Copper and copper alloys — Part 4: Fusion welded butt joints in steel plates up to 50 mm thick ISO Each member body interested in a subject for which a technical committee has been established has the right to 96066-3 represented on that committee.
For explanation of abbreviations used in the designation examples, see clause 4.
This standard covers approval testing of welders for work on semi-finished and 96066-3 products made from wrought, forged or cast material types listed in 5. When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length.
One root fracture test specimen and one face fracture test specimen shall be tested. The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: Is 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.
When welding parent metals from two different groups ixo do not give approval to each other according to table 4 see 6.
This standard applies to the approval testing of welders for the fusion welding of copper. The ability of the welder to follow verbal or written instructions and testing of his skill iiso important factors in ensuring the quality of the welded product.

Each criterion is considered to be a significant factor in the approval testing. Special tests do not have any range of approval, outside the range of tolerances 99606-3 the test carried out.
Prior to mechanical testing, backing strips, where used, shall be removed. The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO Macroscopic tests shall isk carried out in accordance with EN In addition, the requirements for mechanical tests are indicated.
For all other welding positions, two root and two face bend test specimens shall be tested see figure 7 b.
