ISO 15618-1:2016规定了焊工潜水员资格测试的基本要求、资格范围、测试条件、验收要求和认证。 ISO 15618-1:2016适用于钢上的高压湿法焊接。 合格证书测试的推荐格式见附录A。 在资格测试期间，焊工潜水员可能需要证明其具备资格的焊接工艺、材料和安全要求的充分工作知识。关于这些方面的信息见附件B。 ISO 15618本部分所指的焊接工艺包括指定为手动或部分机械化焊接的熔焊工艺。 它不包括完全机械化和完全自动化的过程（见5.2）。 ISO 15618的本部分适用于自发布之日起的所有新资格证书。 然而，ISO 15618-1:2016并未使以前按照国家标准或规范取得的焊工-潜水员资格无效，前提是满足技术要求的意图，并且以前的资格与他们所从事的应用和生产工作相关。 资格考试证书由考官或考试机构全权负责颁发。

ISO 15618-1:2016 specifies essential requirements, ranges of qualification, test conditions, acceptance requirements and certification for the qualification testing of welder-diver performance. ISO 15618-1:2016 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 be 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 designated 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, ISO 15618-1:2016 does not invalidate previous welder-diver qualifications made to former 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 the examiner or examining body.
