The invention is a common used Ti-Ca weld rod, which can be used when the angle 0 (theta) is either positive or negative. The main materials and their weight ratios are 10-40 for rutile, 3-15 for titanium dioxide powder, 10-30 for marble, 10-20 for ilmenite, 3-10 for cellulose, the ferrotitanium and the medium carbon ferromanganses are used as the main deoxidizer. In vertical downward welding, the rod will not drop wilding slag and melt iron, the melt cover ratio is larger than 95%, and there are no weld defects, but a highly qualified welding tip. Compared with common Ti-Ca type weld rod, the invention has higher impact value, alphak is not less than 18kg-m/cm2, and higher efficiency. |
