39、usion welding of steels in a hyperbaric wet environment.The ability of the welder-diver to follow verbal or written instructions and testing of his skill are therefore important factors in ensuring the quality of the welded product.Testing of skill to this part of ISO 15618 depends on welding method
40、s in which uniform rules and test conditions are complied with, and standard test pieces are used.The principle of this part of ISO 15618 is that a qualification test qualifies a welder-diver not only for the conditions used in the test, but also for all other conditions which are considered easier
41、to weld in accordance with this part of ISO 15618. It is presumed that the welder-diver has received training and/or has industrial practice within the range of qualification.This part of ISO 15618 is intended to provide the basis for the mutual recognition by examining bodies for qualification rela
42、ting to the welder-divers competence in the various fields of application. Tests are to be carried out in accordance with this part of ISO 15618 unless additional tests are specified by the relevant application standard when these should be applied.The welder-divers skill and job knowledge continue
43、to be approved only if the welder-diver is working with reasonable continuity on welding work within the extent of qualification.DIN EN ISO 15618-1:2016-12EN ISO 15618-1:2016 (E)5 1 ScopeThis part of ISO 15618 specifies essential requirements, ranges of qualification, test conditions, acceptance req
44、uirements and certification for the qualification testing of welder-diver performance.This part of ISO 15618 is applicable for hyperbaric wet welding on steel.The recommended format for the certificate of qualification testing is given in Annex A.During the qualification test, the welder-diver may b
45、e required to show adequate job knowledge of the welding processes, materials and safety requirements for which he is to be qualified. Information on these aspects is given in Annex B.The welding processes referred to in this part of ISO 15618 include those fusion welding processes which are designa
46、ted as manual or partly mechanised welding. It does not cover fully mechanised and fully automatic processes (see 5.2).This part of ISO 15618 applies to all new qualifications from the date of issue.However, this part of ISO 15618 does not invalidate previous welder-diver qualifications made to form
47、er national standards or specifications, providing the intent of the technical requirements is satisfied and the previous qualifications are relevant to the application and production work on which they are employed.The certificate of qualification testing is issued under the sole responsibility of
48、the examiner or examining body.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
