<P>PROBLEM TO BE SOLVED: To provide a titanium oxide raw material for a weld material, in which defective pores are less, and trouble attributable to abnormal water content can be prevented even under a severe welding execution condition during the execution by the welding wire using titanium oxide raw material irrespective of the production area thereof, and to provide the weld material using the titanium oxide raw material for a weld material, and a method for producing a titanium oxide raw material for the weld material. <P>SOLUTION: In the titanium oxide raw material for a weld material, the amount of each element of Na, K, Al and Si constituting clayey ore and clayey ore single body deposited on surfaces of titanium oxide particles, are set in such a manner that the amount of Na+K, and the amount of Al+Si, by mass, to the ratio of the total amount of titanium oxide raw material is 0.001-0.100%, and 0.04-1.30%, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
