Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: Testing of skill to this standard depends on welding methods in which uniform rules and test conditions are complied with, and standard test pieces are used.

BS EN ISO 9606-3:1999

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the 96063. The acceptance requirements for imperfections found by test methods according to this standard shall, unless otherwise specified, be assessed following EN The welding position H-L for pipes approves for all pipe angles in production work.

This annex outlines the job knowledge that a welder should have to ensure that procedures are followed and common practices are complied with. If any special tests are to be carried out because of the characteristics of particular welding processes, materials or dissimilar alloys, ixo shall be defined prior to carrying out the welder’s test. The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: Dimensions of test piece for fillet weld s on plate Dimensions in millimetres Figure 3: For welding position PA or PC, one root and one face bend test specimen shall be tested see figure 7 a.

Owing to different training programmes in various countries, it is only proposed to standardize general objectives or categories of job knowledge.

For example in a case where approval is required for a single-side butt joint with the root to lso welded by TIG without backing and to be filled by MIGthe welder can be approved by either of the following routes: 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.

If the welder fails any of the prescribed tests, no certificate shall be issued.

This standard covers the following welding processes: The macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required. A welder is approved if 9066-3 imperfections in the test piece are within the specified limits of level B in ENexcept for imperfection types as follows: 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publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August Reference should also be made to the corresponding acceptance criteria 9606- non-destructive examination.


When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length. The range of approval 966-3 each type of test is given in the relevant sub-clauses and tables.

The welder’s approval test certificate shall be issued at least in one of the official CEN languages English, French, German. 906-3 undated references the latest edition of the publication referred to applies.

The number of fracture or transverse bend test specimens depends on the welding position. The test of job knowledge is limited to the matters related to the welding process used in the test. 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.

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.

One root fracture test 9660-3 and one face fracture test specimen shall be tested. When the filler metal is dissimilar to the parent metal group, an approval for that combination of parent metal group and filler 96606-3 is needed, except when permitted by table 4. 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 Preparation and fracture testing of test specimens for a fillet weld on plate 7.

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 Figure c shows the notch profile q d Fracture testing, face side e Fracture testing, root side Figure 7: 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.

Throughout the text of this standard, read ” Preparation and fracture testing of test specimens for a 906-3 weld on pipe When macroscopic examination in accordance with EN is used, at least four test specimens shall be taken equally spaced around the pipe. In these tables the range of approval is indicated in the same horizontal line.


A welders approval is valid 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 the following conditions are fulfilled: Each test specimen shall be positioned for breaking as shown in figure 6b, and examined after fracture.

ISO – Approval testing of welders — Fusion welding — Part 3: Copper and copper alloys

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 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. If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN If any of these conditions are not fulfilled, the approval shall be revoked.

It does not cover fully mechanized and automatic processes see 5. Titanium and titanium alloys — Part 6: This standard applies to the approval testing of welders for the fusion welding of copper.

The job knowledge indicated in this annex is only pitched at io most basic level. 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 This standard is applicable when the welder’s approval testing is required by the purchaser, by inspection authorities or by other organizations.

When transverse bend testing is used, one root bend test specimen and one face bend test specimen shall ieo tested in accordance with EN When welding parent metals 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 A change of process requires a new approval test.

The certificate of approval testing is issued under the sole responsibility of the examiner or examining body. When transverse bend testing is used, it shall be carried out in accordance with EN If the imperfections in the welder’s test piece exceed the permitted maximum specified, then the welder shall not be approved.
