本项目系大庆石油管理局油田安装工程公司焊条厂和哈尔滨焊接研究所共同研究开发的.研制的焊条属于高纤维素钛型药皮立向下专用焊条,采用直流反接,用于低合金钢环缝全位置下行焊接及薄板直缝下向焊,具有一定的电弧吹力和熔深、多层焊可单面焊双面成形.下行焊时铁水及熔渣不下淌,焊缝成型美观,有利于提高焊接质量.
This project is jointly researched and developed by electrode factory of Daqing Petroleum Administration Oilfield Installation Engineering Company and Harbin Welding Research Institute.The welding rod belongs to the high-cellulose titanium vertical special electrode, adopts DC reverse connection and is used for low-alloy steel The full position of the ring seam down the line welding and sheet metal seam welding, with a certain arc blowing force and penetration, multi-layer welding can be single-sided welding double-sided forming. Downward welding hot metal and slag does not drip, the weld is beautiful, Help to improve the welding quality.
