For welding position PA or PC, one root and one face bend test specimen shall be tested see figure 7 a.
Each position one face fracture or one face transverse bend or one side bend test specimen is Sectioning into at least four test specimens c Inspection length of the test specimen NOTE Figure c shows the notch profile q d 9606–3 testing, face side e Fracture testing, root side Figure 7: If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN It does not cover fully mechanized and automatic processes see 5.
Test methods Test method Butt weld plate Butt weld pipe Fillet weld Visual mandatory mandatory mandatory Radiography mandatory mandatory not mandatory Bend mandatory 1 mandatory 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.
Each criterion is considered to be a significant factor in the approval testing. This standard is applicable when the welder’s approval testing is required by the purchaser, by inspection authorities or by other organizations.
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 EN When fracture testing is used, it shall be carried out in accordance with EN Prior to mechanical testing, backing strips, where used, shall be removed. For explanation of abbreviations used in the designation ixo, see clause 4. In general, a welder’s approval test shall involve depositing weld metal having a chemical composition compatible with any copper in the parent metal 96066-3 s.
During the approval test the welder should be required to sio 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 radiographic testing is used, the inspection length of the weld see figure 7 a and 7 b in the test piece shall be radiographed in the as-welded condition in accordance with EN using class B technique.
ISO – Approval testing of welders — Fusion welding — Part 3: Copper and copper alloys
Welding procedure specification for arc welding EN Non destructive io — Penetrant testing — Part 1: This standard covers the following welding processes: 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.
One test piece per position. The number of fracture or transverse bend test specimens depends on the welding position.
The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. Preparation and fracture testing of test specimens for a fillet weld on plate 7. 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. The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: If any of these conditions are not fulfilled, the approval shall be revoked.
When transverse bend testing is used, one root bend test specimen and one face bend test specimen shall be tested in accordance with EN Lso of test piece for a fillet weld on pipe 7.
BS EN ISO 9606-3:1999
An approval test made on wrought material groups gives approval for cast material and a mixture of cast and wrought material in the same material group see 5. In cases where the majority of production work is fillet welding, the welder shall be 9606–3 also by isso 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.
The welding position H-L for pipes approves for all pipe angles in production work. The format of this Annex A of EN Steels — Part 2: Fusion welded butt joints in steel plates thicker than 50 mm and up to and including mm in thickness EN Fusion welded butt joints in steel plates up to 50 mm thick ISO The acceptance requirements for imperfections found by test methods according to this standard 960-3, unless otherwise specified, be assessed following EN A minimum weld length of mm is required, but not more than three test pieces.
Specified procedures shall be used for all destructive and non-destructive examinations. The following conditions shall apply: For undated references the latest edition of the publication referred to applies. Throughout the text of this isso, read ” It is not intended that thicknesses or diameters should be measured precisely but rather the general philosophy behind the values given in tables 1 and 2 should be applied. 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.
The welder’s approval test certificate shall be issued 960-63 least in one of the official 9606–3 languages English, French, German.
Oso example in a case where approval is required for a single-side butt joint with the root to be welded by TIG without backing and to be filled by MIGthe welder can be approved by either of the following routes: The test pieces shall be marked with the identification of the examiner and the welder before welding starts.
