磁性焊剂 CO_2明弧半自动焊是一种先进的焊接方法。但直到目前为止,国内外对磁性焊剂渣系及焊接工艺的系统资料还很少。在这种情况,我们本着多快好省及土洋结合的原则进行了实验研究,并取得了一些结果,尤其对于 TiO_2-CaO-SiO_2渣系的磁性焊剂方面的研究。本研究工作由天津大学焊接专业、天津船舶修造厂、新港船厂及新河船厂四个单位协作共同进行的。 Magnetic flux CO_2 bright arc semi-automatic welding is an advanced welding method. However, until now, there are still few systematic data on magnetic flux slag lines and welding processes at home and abroad. In this case, we carried out experimental research based on the principle of combining the best and the best, and achieved some results, especially on the magnetic flux of TiO_2-CaO-SiO_2 slag system. The research work was jointly carried out by four units of welding major of Tianjin University, Tianjin Ship Repair Factory, Xingang Shipyard and Xinhe Shipyard.
