This European Standard specifies main requirements, limits, inspection conditions and acceptance requirements as well as related inspection documents of welders for welded cast iron test pieces and workpieces. It provides a set of technical rules for a systematic qualification test of a welder's skills, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body. This European Standard specifies the testing of a welder's skill unless a higher level skill test is applicable. The acceptance of a welder's skill according to this European Standard implies a practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C). This European Standard has to be used when requirements on part of a customer, testing or monitoring body or other organisation are postulated. This European Standard defines the qualification test of welders for the fusion welding of cast iron. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418). Cast iron materials which are covered by this European Standard are mentioned in 5.4. The inspection document and certification is made out in the name of the testing body's liability.

EN 287-6:2010 (E) 4 Introduction The ability of a welder to follow verbal or written instructions and verification of a person's skills are important factors in ensuring the quality of the welded product. The testing of a welder's skill in accordance with this standard depends on welding techniques and conditions used in which uniform rules are complied with, and standard test pieces are used. The principle of this European Standard is that a qualification test qualifies the welder not only for the conditions used in the test, but also for all joints which are considered easier to weld on the presumption that the welder has received a specific training and/or has industrial practice within the range of qualification. The qualification test can be used to qualify a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions, are satisfied. SIST EN 287-6:2010



EN 287-6:2010 (E) 5 1 Scope This European Standard specifies main requirements, limits, inspection conditions and acceptance requirements as well as related inspection documents of welders for welded cast iron test pieces and workpieces. It provides a set of technical rules for a systematic qualification test of a welder‘s skills, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body.
This European Standard specifies the testing of a welder’s skill unless a higher level skill test is applicable. The acceptance of a welder’s skill according to this European Standard implies a practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C). This European Standard has to be used when requirements on part of a customer, testing or monitoring body or other organisation are postulated.
This European Standard defines the qualification test of welders for the fusion welding of cast iron. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418). Cast iron materials which are covered by this European Standard are mentioned in 5.4. The inspection document and certification is made out in the name of the testing body’s liability. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 287-6:2010 (E) 8 5 Essential variables 5.1 General The qualification of welders is based on essential variables. For each essential variable, a range of qualifica-tion is defined. All test pieces shall be welded using the essential variables independently. The test piece for the qualification test is unattached from the type of component. 5.2 Welding processes The welding processes are defined in ISO 857-1 (see also 4.2). 5.3 Type of weld and joint preparation For those butt and fillet weld test pieces made of cast iron plates with tapped blind holes and for those test pieces made of cast iron with simulated cracks the qualification test shall be made according to 7.2. 5.4 Material groups 5.4.1 General In order to reduce the number of qualification tests, materials with similar welding characteristics are grouped according to CEN ISO/TR 15608 (see also 5.4.2). 5.4.2 Cast iron groups According to the operational requirements the following cast iron materials are relevant. Cast iron groups according to CEN ISO/TR 15608: 71 grey (lamellar graphite) cast iron; 72 spheroidal graphite cast iron; 73 malleable cast iron; 74 austempered ductile cast iron; 75 austenitic cast iron; 76 other cast iron materials. 5.5 Weld metals It is differentiated between homogeneous weld metal (hw), semi-homogeneous weld metal (sw) and non-homogeneous weld metal (nw). For the qualification test, suitable consumables shall be selected in view of the parent metal and the welding process. The welding process shall conform to the relevant pWPS or WPS (see EN ISO 15609-1 and EN ISO 15609-2). If a qualification test is made by using one kind of welding consumables, shielding gases or welding fluxes the test will also be accepted for comparable types of welding consumables, shielding gases or welding fluxes for the same cast iron material group. SIST EN 287-6:2010



EN 287-6:2010 (E) 9 5.6 Welding positions The welding position shall be chosen in accordance with Figure C.1. The welding positions and symbols refer to EN ISO 6947. The test pieces shall be welded in accordance with the nominal angles of the welding positions according to EN ISO 6947. 6 Range of qualification 6.1 General As a basic principle the qualification test of a welder not only covers the referring test piece and the skill for these special variables, it also covers joints and appropriate variables which are easier to create. 6.2 Welding process Each qualification test refers to one welding process. A change of the welding process requires a new qualification test. 6.3 Welding position The welding position PB includes the position PA. The welding position PC includes the positions PA and PB. The welding position PF includes the positions PB and PA. NOTE The positions of weld are illustrated in Figure C.1. 6.4 Cast iron material groups See CEN ISO/TR 15608 (see also Table A.1).
