新日本制铁公司、日本控制器公司和东亚压接公司共同研制的粗钢筋气焊自动压接对焊装置,经过工程试用,在一些设备基础工程上做过一万多个钢筋接头的焊接,并经日本焊接学会的技术鉴定,现已向工程界推广,正式用于一般施工。这一装置由三部分组成:即加热部分(包括燃烧器和传动装置)、加压部分(包括钢筋卡头和油泵)和自动控制部分。三部分之间的组合如图1所示。
The automatic pressure welding butt welding device for coarse steel gas welding jointly developed by Nippon Steel Corporation, Japan Controller Corporation and East Asia Crimping Co., Ltd. has undergone engineering trials and has done welding of more than 10,000 steel joints in some basic equipment projects. The technical appraisal of the Japan Welding Society has now been promoted to the engineering community for formal use in general construction. This device consists of three parts: the heating part (including the burner and the transmission), the pressurizing part (including the reinforcing bars and the oil pump) and the automatic control part. The combination of the three parts is shown in Figure 1.
