[align=left]本人再说《钢筋焊接接及验收规程》（JGJ 18-2012）中试件断裂结果判断的问题。此贴本应发于2013年末，但因本人确实比较懒，至今才得以出炉。此次续说较前贴有如下几点变化：一是根据陕西省建筑科学研究院钢筋焊接及验收规程管理组回复福建省建设工程质量安全监督总站《关于JGJ18-2012中5.1.7的补充说明》（便函254号）文件，对原判定结果进行更正；二是请教了本规程主要起草人陕西省建筑科学研究院吴成材高工，对“无效”结果的判断进行了明确；三是增加了对复检结果合格情况的列举。至此，在本人将钢筋焊接试验结果全部情况一一列出，各位可对照本表根据实际发生的情况进行对比判断，从而有效避免错判与漏判问题的发生。此上仅供同仁参考。

[align=left]在此衷心感谢吴老先生对试验检测工作的大力支持！
