BS EN 287-6:2018 pdf download.Qualification test of welders – Fusion welding
1 Scope
This document 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 or examining body. This document specifies the testing of a welder’s skill unless a higher level skill test is required. The acceptance of a welder’s skill in accordance with this document implies a practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C). This document is to be used when requirements on part of a customer, testing or monitoring body or other organization are postulated. This document defines the qualification test of welders for the fusion welding of cast irons. 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 ISO 14732]. Cast iron materials which are covered by this document are mentioned in 5.4. The inspection document and certification are made out under the responsibility of the testing body.
9 Re-test
If any test fails to comply with the requirements of this European Standard, the welder shall be given the opportunity to repeat the qualification test. If it is established that failure is due to metallurgical or other extraneous causes that cannot be directly attributed to the welder’s lack of skill, an additional test is required in order to assess the quality and integrity of the new test material and/or new test conditions.
10 Period of validity
10.1 Initial qualification
The validity of the welders qualification begins from the date of welding of the test piece(s).This is providing that the required testing has been carried out and the test result obtained were acceptable.
10.2 Confirmation of the validity
The welder’s qualification test certificate issued is valid for a period of two years. This is providing that the welding co-ordinator or the responsible personnel of the employer can confirm that the welder has been working within the initial range of qualification. This shall be confirmed every six months.
10.3 Prolongation of qualification
Welder’s qualification test certificates in accordance with this standard can be prolonged every two years by an examiner/ examination body.
Before prolongation of the certification takes place, 10.2 needs to be satisfied and also the following conditions need to be confirmed:
a] all records and evidence used to support prolongation are traceable to the welder and identifies the WPS’ (s) that have been used in production;
