前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件修改采用ISO15614?10：2005《金屬材料焊接程序規(guī)范和鑒定焊接程序試驗(yàn)第10部

分：高壓干焊》。

本文件與ISO15614?10：2005相比作了下述結(jié)構(gòu)調(diào)整：

—第8章中8.5.2和8.5.3對(duì)應(yīng)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。

本文件與ISO15614?10：2005的技術(shù)差異及其原因如下：

—在適用范圍中加入了修復(fù)焊接，以便于標(biāo)準(zhǔn)的實(shí)施；

—?jiǎng)h除了ISO原文中未引用的術(shù)語（見第3章），以便于標(biāo)準(zhǔn)實(shí)施；

—用規(guī)范性引用的GB/T19866

替代了ISO15607：2003、GB/T44527替代了ISO15618?2：2001（見

第3章、第7章）；用規(guī)范性引用的GB/T19867.1替代了ISO15609?1：2004（見第4章、第9章）；

用規(guī)范性引用的GB/T16672

替代了ISO6947：1990（見6.3）；增加規(guī)范性引用的GB/T40424

，

刪除了EN228?9（見第7章、第8章）；用規(guī)范性引用的GB/T5185

替代了ISO4063：1998（見

8.5.1）；用規(guī)范性引用的GB/T39255替代了ISO14175：2008（見8.5.3），以適用我國技術(shù)要求；

—?jiǎng)h除了板試件的形狀和尺寸要求的規(guī)范性引用ISO15618?2：2001，用示意圖替代，便于標(biāo)準(zhǔn)

實(shí)際應(yīng)用（見6.2）；

—?jiǎng)h除了關(guān)于試件的焊接中常識(shí)性內(nèi)容的注（見6.3）；

—增加了對(duì)于焊接方法代號(hào)要求，便于標(biāo)準(zhǔn)實(shí)際應(yīng)用（見8.5.1）；

—在方法代號(hào)中加入了激光焊（見8.5.1），以適用于激光焊接方法；

—在特定焊接方法中加入了關(guān)于激光焊的要求（見8.5.1和8.5.4），以適用于激光焊接方法；

—更改了表2中對(duì)于深度降低重新評(píng)定的要求，便于標(biāo)準(zhǔn)的實(shí)際應(yīng)用（見8.6）。

本文件做了下列編輯性修改：

—將標(biāo)準(zhǔn)名稱修改為《水下高壓干式焊接工藝評(píng)定試驗(yàn)》；

—增加了資料性附錄A。

請(qǐng)注意本文件的某些內(nèi)容可能涉及專利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識(shí)別專利的責(zé)任。
