• 某机电安装公司承担了某钢厂新厂区油罐组焊，燃气、氧气管道安装施工，设计要求焊缝进行射线无损探伤检查。强度试验采用气压试验方法。

  该公司在编制施工方案时，对油罐组焊、管道焊接方案采用综合评价法进行了技术经济比较，选定了最优方案。

  管道焊后经射线探伤发现，焊接合格率偏低。项目部组织人员按质量预控的施工因素进行了分析，经查验，工艺文件已按程序审批，并进行了技术交底。但焊接记录中有部分焊材代用，部分焊机不符合要求，焊缝外观检查有漏检。根据分析结果，找出了失控原因，经整改后焊接合格率得到了提高。

  项目部根据现场危险源辨识，编制了高处作业、机械操作、起重吊装、临时用电安全技术措施。

  技术交底主要包括哪些方面？
