An approval test made on wrought material groups gives approval for cast material and a mixture of cast and wrought 960-3 in the same material group see 5.

Special tests do not have any range of approval, outside the range of tolerances for the test carried out. One root fracture test specimen and one face fracture test specimen shall be tested. In addition, the requirements for mechanical tests are indicated. Preparation and fracture testing of test specimens 9606-33 a fillet weld on plate isp. 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.

Nickel and nickel alloys — Part 5: The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO Macroscopic tests shall be carried out in accordance with EN This annex outlines the job knowledge that a welder should have to ensure that procedures are followed and common practices are complied with.

Testing of skill to this standard depends on welding methods in which uniform rules and test conditions are iao with, and standard test pieces are used. This European Standard shall be given the status of a national standard, either by publication of an identical oso or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August The welding of any one material in a group confers 960-63 on the welder for the welding of all other materials within the same group.


If the imperfections in the welder’s test piece exceed the permitted maximum specified, then the welder shall not be approved. Test specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A.

The welder’s approval test certificate shall be issued at least in one of the official CEN languages English, French, German.

BS EN ISO 9606-3:1999

When fracture testing is used, it shall be carried out in accordance with EN In general, a welder’s approval test shall involve depositing weld metal having a chemical composition compatible with any copper in the parent metal group s.

Reference should also be made to the corresponding acceptance criteria for non-destructive examination. One test piece per position. If any special tests are lso be carried out because of the characteristics of particular welding processes, materials or dissimilar alloys, these shall be defined prior to carrying out the welder’s test.

If any of these conditions are not fulfilled, the approval shall be revoked. 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 macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required.


The term ”copper” stands for copper and weldable copper alloys. A change of process requires a new approval test. This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to welders’ competence in the various fields of application.

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. The examiner or examining body can stop the test if the welding conditions are not correct or ixo it appears that the welder does lso have the technical competence to comply to the requirements of this standard, e. A full explanation of these imperfections is given in EN All relevant test conditions shall be recorded on the certificate.

A Reference number ISO This standard covers approval testing of isp for work on semi-finished and finished products made from wrought, forged or cast material types listed in 5. The test pieces shall be marked with the identification of the examiner and the welder before welding starts. The range of approval for each type of test is given in the relevant sub-clauses and tables.
