标准范围

本标准规定了基本要求、批准范围、试验条件、验收要求和镍焊接焊工性能认可测试认证。本标准适用于镍熔焊焊工的认证测试。本标准旨在提供审查机构相互承认的基础，以供批准焊工在各个应用领域的能力。试验将按照本标准进行，除非应用时，相关应用标准规定了更严格的测试。在批准测试期间，焊工应表现出足够的实践经验和工作知识（测试）（非强制性）焊接工艺、材料和安全要求的批准；信息关于这些方面的信息，见附件A。本标准适用于买方、检验机构或承包商要求焊工进行认证测试的情况由其他组织提供。本标准中所指的焊接工艺包括以下熔焊工艺:手工或部分机械化焊接。它不包括全机械化和自动化过程（见5.2）。本标准涵盖了焊工在锻造材料制成的半成品和成品上工作的批准测试，表5所列的锻造或铸造材料类型。4.认证测试证书由检验员或检验机构全权负责签发。

This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements andcertification for the approval testing of welder performance for the welding of nickel.This standard applies to the approval testing of welders for the fusion welding of nickel.This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating towelders' competence in the various fields of application. Tests will be carried out in accordance with this standard unlessmore severe tests are specified by the relevant application standard when these are applied.During the approval test the welder should be required to show adequate practical experience and job knowledge (testnon mandatory) of the welding processes, materials and safety requirements for which he is to be approved; informationon these aspects is given in Annex A.This standard is applicable when the welder's approval testing is required by the purchaser, by inspection authorities orby other organizations.The welding processes referred to in this standard include those fusion welding processes which are designated asmanual or partly mechanized welding. It does not cover fully mechanized and automatic processes (see 5.2).This standard covers approval testing of welders for work on semi-finished and finished products made from wrought,forged or cast material types listed in 5.4.The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.
