jgj18最新规范JGJ18-2012钢筋焊接及验收规范JGJ18-2012钢筋焊接及验收规范本文介绍了行业标准JGJ18—2012中主要修订内容的技术背景，并对大家关注的第5章“质量检验与验收”进行解读。
希望土建专业技术人员学习并实施好JGJ18—2012，确保钢筋焊接质量。
行业标准《钢筋焊接及验收规程》JGJ18—2012经住房和城乡建设部批准发布，已于2012年8月1日起实施。
其中，第3.0.6、4．1.3、5.1.7、5.1.8、6.0.1、7.0.4条为强制性条文，必须严格执行。
原行业标准《钢筋焊接及验收规程》JGJ18—2003同时废止。
《钢筋焊接及验收规程》JGJ18规程正在修改之中，相对现行的JGJ18―2003，新修订的规程部分有部分进行了较大的调整，修改重点：1：增加“焊接安全”章节。
2：增加新型细晶粒钢筋HRBF400在各种焊接中的应用。
3：将电渣焊的焊接直径下限扩大到12mm，气压焊的焊接直径下限扩大到10mm。
4：质量验收中，按照合格、复检、不合格三个部分排列，更有利于质量判定。
5：增加“埋弧螺柱焊”该规程的“报批稿”在2010年10份定型。
JGJ18-2010钢筋焊接及验收规程还在报批中,经批准公示后，还有要有一个发布日期，一个实施日期，通常实施日期比发布日期还有晚半年左右。
钢筋的检验与钢筋接头的工艺检验：钢筋的检验首先要检查钢筋的标牌号及质量证明书；其次要做外观检查，从每批钢筋中抽取5% ，检查其表面不得有裂纹、创伤和叠层，钢筋表面的凸块不得超过横肋的高度，缺陷的深度和高度不得大于所在部位的允许和偏差，钢筋每一米弯曲度不应大于四米；接下来力学性能试验，每批若小于60吨则从中抽取2根，每根截取两段，分别做拉伸和冷弯试验。
在截取试件时应除去钢筋两端100－500MM，在截取试件大于60吨还需在取相应的钢筋。
如果一项试验结果不符合要求，则从同一批中另取双倍数量的试样做各项试验。
