TITANIUM COMPOUND MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a titanium compound material which enables to shorten a construction period of a water storage tank, resulting in a reduction of a production cost. SOLUTION: A titanium clad steel 22 is attached to a surface of a base material 21 being composed of an iron system metal with a steel layer 23 downward. A surface of the base material 21 and a bottom surface of a steel layer 23 of the titanium clad steel 22 are welded with a seam welder for forming a weld part 28. A titanium compound material 29 thus formed can be used for forming a water storage tank shell by bending in an arc shape with the titanium clad steel 22 inside.
