钢筋焊接及验收规程

ＪGＪ18—201２

施行日期:2０１2年０8月０１日

前言

根据住房和城乡建设部建标[2009］８8号文的要求,标准修订组认真贯彻国家节材节能，

环境保护的政策，调查研究，进行大量钢筋焊接试验,总结实践经验,参考国内外相关标准和

资料,并在广泛征求意见的基础上修订、编制了本规程。

本规程主要技术内容是:1总则；2术语和符号；3材料;4钢筋焊接；５质量检验与验收;6

焊工考试；7焊接安全。

本规程修订的主要内容：1。增加了术语和符号;2.根据国家现行标准，特别是GB1499．2—

２0０7《钢筋混凝土用钢第2部分：热轧带肋钢筋》中细晶粒钢筋的出现，做了细晶粒钢筋各

种焊接方法的试验后，增加了适用于焊接的钢筋牌号和规格;3.对用于钢筋电渣压力焊的钢筋

下限直径，从１4mｍ延伸至12mm;4.在焊接工艺方法方面，将箍筋闪光对焊从原来“钢筋闪光

对焊”中列出,增补内容,单独成节；５。在钢筋电弧焊中，增加了ＣO气体保护电弧焊的内

2

容；６.在钢筋气压焊方面,增加了半自动钢筋固态气压焊和钢筋氧液化石油气熔态气压焊的

内容；7。在预埋件T形接头焊接中增加了钢筋埋弧螺柱焊。

在质量检验与验收的一般规定中,对于焊接接头拉伸试验质量要求作了较大修改，更好地

符合生产实际,便于操作；对焊箍筋接头质量要求,独立成节;增加对焊箍筋接头、预埋件钢筋

T型接头的连接方式和力学性能检验为主控项目.

新增第7章焊接安全.

本规程中以黑体字标志的条文为强制性条文,即：1.0.4，３．0.8，4。1。4,5.１.９，

5.１。１0共五条,必须严格执行。与JＧJ18－２003中条文比较，条文内容有所修改补充.

本规程第1版于1９６5年批准发布以来,随着钢筋焊接技术的不断发展，经８4版、９6版、

2003版，至此已是第四次修订.钢筋焊接技术具有很多优越性,是一项节材、节能、少尘、少

烟的环保技术,钢筋焊接工作者应正确实施规程,确保质量，降低成本,精益求精，有所创新，

为国家经济建设作贡献。
