PURPOSE:To develop a cored wire for welding having attitude weldability and mechanical properties of a weld metal by mixing a specific amt. of lower oxide with the Ti oxide in the cored wire for welding formed filled with a flux consisting essentially of Ti oxide. CONSTITUTION:A flux which consists essentially of a Ti oxide and is mixed with a slag agent, arc stabilizing agent, alloying agent and deoxidizing agent is filled as a flux into a cored wire for welding made by enclosing the flux in a steel sheath, at 8-25% by the total weight of the wire. Said Ti oxide consists of pulverous powder in which <=100 mesh grain sizes occupy >=50%. Said oxide is so compounded that the lower oxides such as Ti2O3 and Ti3O5 are incorporated at 20-80% of the entire Ti oxide including TiO2. The cored wire for welding having excellent attitude weldability and mechanical properties of the weld zone is obtd. |
