前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件修改采用ISO15614﹘10：2005《金属材料焊接程序规范和鉴定焊接程序试验第10部

分：高压干焊》。

本文件与ISO15614﹘10：2005相比作了下述结构调整：

—第8章中8.5.2和8.5.3对应ISO15614﹘10：2005第8章中的8.5.1和8.5.2，增加了8.5.1和8.5.4。

本文件与ISO15614﹘10：2005的技术差异及其原因如下：

—在适用范围中加入了修复焊接，以便于标准的实施；

—删除了ISO原文中未引用的术语（见第3章），以便于标准实施；

—用规范性引用的GB/T19866

替代了ISO15607：2003、GB/T44527替代了ISO15618﹘2：2001（见

第3章、第7章）；用规范性引用的GB/T19867.1替代了ISO15609﹘1：2004（见第4章、第9章）；

用规范性引用的GB/T16672

替代了ISO6947：1990（见6.3）；增加规范性引用的GB/T40424

，

删除了EN228﹘9（见第7章、第8章）；用规范性引用的GB/T5185

替代了ISO4063：1998（见

8.5.1）；用规范性引用的GB/T39255替代了ISO14175：2008（见8.5.3），以适用我国技术要求；

—删除了板试件的形状和尺寸要求的规范性引用ISO15618﹘2：2001，用示意图替代，便于标准

实际应用（见6.2）；

—删除了关于试件的焊接中常识性内容的注（见6.3）；

—增加了对于焊接方法代号要求，便于标准实际应用（见8.5.1）；

—在方法代号中加入了激光焊（见8.5.1），以适用于激光焊接方法；

—在特定焊接方法中加入了关于激光焊的要求（见8.5.1和8.5.4），以适用于激光焊接方法；

—更改了表2中对于深度降低重新评定的要求，便于标准的实际应用（见8.6）。

本文件做了下列编辑性修改：

—将标准名称修改为《水下高压干式焊接工艺评定试验》；

—增加了资料性附录A。
