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?13：2023《金屬材料焊接工藝規(guī)程和資格評定焊接工藝試驗

第13部分：電阻對焊和閃光對焊》。

本文件與ISO15614?13：2023的技術(shù)差異及其原因如下：

—為適應(yīng)我國技術(shù)條件，修改了范圍（見第1章）；

—用規(guī)范性引用的GB/T228.1替換了ISO6892?1（見6.2.2，7.3.1）；用規(guī)范性引用的

GB/T2651替換了ISO4136（見6.2.2）；用規(guī)范性引用的GB/T2653替換了ISO5137

（見6.2.3，7.3.2，7.3.4）；用規(guī)范性引用的GB/T6417.2替換了ISO6520?2（見第3章）；用

規(guī)范性引用的GB/T8366替換了ISO669（見第3章）；用規(guī)范性引用的GB/T11345替換了

ISO17640（見7.2.6）；用規(guī)范性引用的GB/T19805替換了ISO14732（見第5章）；用規(guī)范

性引用的GB/T19866替換了ISO15607（見第3章）；用規(guī)范性引用的GB/T19867.5替

換了ISO15609?5（見第4章，第9章）；用規(guī)范性引用的GB/T26953替換了ISO23277

（見7.2.3）；用規(guī)范性引用的GB/T26955替換了ISO17639（見7.4）；用規(guī)范性引用的

GB/T27552替換了ISO9015?2（見6.2.5，7.5）；用規(guī)范性引用的GB/T29711替換了

ISO23279（見7.2.6）；用規(guī)范性引用的GB/T29712替換了ISO11666（見7.2.6），以適用我

國技術(shù)要求；

—刪除了ISO15620：2019，采用直接引用示意圖的形式（見圖1），刪除了7.2.1的“例如”的

內(nèi)容；

—增加了GB/T26951（見7.2.4）、GB/T26952（見7.2.4）、GB/T26954（見7.2.5）和

GB/T32259（見7.2.2）的引用，便于應(yīng)用。

本文件做了下列編輯性改動：

—將標(biāo)準(zhǔn)名稱修改為《電阻對焊和閃光對焊的焊接工藝評定試驗》；

—刪除了ISO15614?13：2023的6.2.4、7.3.3條文腳注。

—用資料性引用的GB/T5185替換了ISO4063：2023（見表A.2，表A.3）。
