日本川崎钢公司已开发出干线用管双面焊接系统,可使焊接时间比传统的单面焊接机缩短2/3。 新焊接系统包括已实际运用的川崎外侧自动焊接机,装有一新开发的内焊接系统,同时从内侧焊接钢管。 内焊接系统是由排成一列的装有一焊炬的3个推进器,一个定位开坡口用电子传感器,2台监视摄像机和1个遥控系统组成。用一可微调电压的稳弧装置,以使产生的电弧处于稳定状
Kawasaki Steel Co., Ltd. of Japan has developed a double-sided pipe welding system, which can make the welding time shorter than the traditional single-sided welding machine 2/3. The new welding system includes the practical Kawasaki outside automatic welding machine, which incorporates a newly developed internal welding system, while welding the steel pipe from the inside. The internal welding system consists of three propellers with a welding torch in line, an electronic sensor for positioning the bevel, two surveillance cameras and a remote control system. A trimming voltage stabilizing device is used to stabilize the resulting arc
