CORROSION PREVENTIVE STRUCTURE IN WELD ZONE BETWEEN TITANIUM CLADDED THIN STEEL SHEET AND STEEL BODY

摘要

PROBLEM TO BE SOLVED: To improve corrosion resistance of a steel body to which a titanium cladded thin steel sheet is welded. SOLUTION: In a structure wherein a lining of a titanium cladded thin steel sheet 2 is executed to a steel sheet pile 1 by welding, an end face 2c of the titanium cladded thin steel sheet 2 and a weld metal zone 3 generated by above described welding are covered with a titanium thin sheet 4 to seal them. At this time, the titanium thin sheet 4 is welded to the titanium cladded thin steel sheet 2 by using a titanium stock 5, and the titanium thin sheet 4 is welded to the steel sheet pile 1 by using a brazing filler metal 6.
