前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件修改采用ISO15618?2：2001《水下焊接焊工的合格試驗第2部分：潛水員高壓干焊用

焊工和焊接操作人員》。

本文件與ISO15618?2：2001相比作了下述結構調整：

——增加了附錄A（資料性）鋼材組別分類指南；

——附錄B對應ISO15618?2：2001中的附錄A；

——附錄C對應ISO15618?2：2001中的附錄B，其中C.2對應ISO15618?2：2001中的B.2，增加

了C.2.2；

——附錄C對應ISO15618?2：2001中的附錄B，其中C.2.3對應ISO15618?2：2001中的B.2.2，

增加了C.2.3.3。

本文件與ISO15618?2：2001的技術差異及其原因如下：

——對范圍的內容進行了歸納總結，調整了表述方式（見第1章），便于標準實際應用；

——增加規范性引用的GB/T19866—2005，刪除了EN228?1（見第3章）；增加規范性引用的

GB/T3375，刪除了ISO857?1（見5.2）；增加規范性引用的GB/T5185，刪除了ENISO4063

（見5.2、第12章）；增加規范性引用的GB/T5117，刪除了EN499（見5.5.2）；用規范性引用

的GB/T983替代了ISO3581，刪除了EN1600（見5.5.2）；增加規范性引用的GB/T16672，

刪除了ENISO6947（見5.7、6.7、第12章）；增加規范性引用的GB/T19867.1，刪除了EN228?2

（見7.4、第11章）；增加規范性引用的GB/T32259，刪除了EN970（見7.5）；增加規范性引用的

GB/T26951，刪除了EN1290（見7.5）；增加規范性引用的GB/T18851.1，刪除了EN571?1

（見7.5）；增加規范性引用的GB/T26955，刪除了EN1321（見7.5、7.6.3）；增加規范性引用

的GB/T11345，刪除了EN1714（見7.5、7.6.4）；增加規范性引用的GB/T3323.1—2019，刪

除了EN1435（見7.6.2）；增加規范性引用的GB/T27551，刪除了EN1320（見7.6.2、7.6.3、

7.6.5）；增加規范性引用的GB/T2653，刪除了EN910（見7.6.2、7.6.4）；增加規范性引用的

GB/T19418，刪除了prENISO5817（見第8章）；

——重新規定了符號和縮略語的使用要求（見4.1），便于標準實際應用；

——技能評定的主要參數增加了激光焊（見5.2），以適用我國技術要求；

——加入了對于實心焊絲的認可范圍（見6.5），以適用我國技術要求。

本文件做了下列編輯性改動：

——將標準名稱修改為《水下高壓干式焊接潛水焊工和焊接操作工技能評定》；

——重新繪制了示意圖，并刪除了部分示意圖修飾性的注；

——刪除了對于CRISO15608的引用，并根據其引用內容增加了附錄A（鋼材組別分類指南）（見

5.4），以便于標準實施；

——刪除了第11章中多余的修飾性表述，便于標準實際應用；

——刪除了第12章中的示例，便于標準實際應用；

——在附錄C（專業知識）中增加了關于激光焊的內容（見C.2.2和C.2.3.3），便于標準實際應用。
