7、J闷~J一月吐吕本标准共分11章，是对SL36-92进行的修订，修订的主要技术内容包括:—第1章增加了碳素钢、低合金钢的气体保护电弧焊的技术要求;增加了高强度结构钢(指钢材的屈服强度下限值大于等于400MPa的低碳低合金调质钢或控冷控轧钢即TMCP钢)、不锈钢、不锈钢复合钢板的焊条电弧焊、埋弧焊、气体保护电弧焊的技术要求。—按标准化工作的要求，增加了第3章术语和定义。给出了下列术语和定义:水工金属结构、后热、焊后热处理、碳当量、对接焊缝、角焊缝、组合焊缝、接头部分焊透焊缝、焊缝计算厚度、焊接缺欠、焊接缺陷、返工、无损检测、振动时效。a)明

8、确了对接焊缝、角焊缝、组合焊缝及接头部分焊透焊缝的术语定义。本标准将各种焊接接头的焊缝形式划分为对接焊缝和角焊缝两类，对接焊缝包括全焊透和部分焊透的对接接头、T形接头、角接接头的对接焊缝;角焊
