摘　　要：采用最新研制的半自动钢筋闪光焊设备,对HRB400钢筋进行了钢筋闪光焊工艺实验,计算了HRB400钢筋的碳当量,观察了焊接接头的微观组织状况。结果表明,采用该焊接设备焊接的钢筋接头的抗拉和弯曲试验结果100%满足行业标准《钢筋焊接及验收规程》(JGJ18-2003)的质量检验要求,组织状况符合一般钢筋焊接接头的普遍规律。采用该设备焊接的HRB400钢筋接头质量稳定,工人劳动强度低。With a new Automatic Flash-butt Welding Equipment,Experiments to weld the HRB400 Rebars were carried out in the paper.The carbon equivalent of the rebar material was calculated.The micro-structure of the welded joints between the rebars was observed.The results showed that the strength and bending property of the HRB400 welded joints could be satisfied perfectly the quality requisition complied with the professional standard ,the Rule of Welding and Quality Checking of the Rebar（JGJ18-2003）.By the equipment, the quality of the welding joints was stable ,the strength of the labor was descended.
