1) As expected in the first report, when the points showing the composition of welding core rodsare in the field II of the diagram (Tig 5) of deoxidatibn with manganese and silicon, the followingresults are obtained. (a) The weld steels deposited by them are denser and ,the mechanical properties (especially elongation) are more excellent than others deposited by the core rods whose composition-points are in the field I of the diagrrm (b) The higher the contents of manganese and silicon are, or the higher the silicon contents are under the constant manganese, the denser are the weld steels deposited by them and the more excellent the ultimate strengths and elongations 2) Even though the points showing the compositions of the welding core rods are in the field IIof the diagram, when the contents of manganese and silicon are excessively high, there is a tendencyfor the ultimate strengths of the weld steels deposited by them in certain conditions to become lower. 3) When steel core rods containing manganese and silicon are used, the coating must be freefrom calcium fluoride to obtain the bead having no small hole which opens at the surface.
