PROBLEM TO BE SOLVED: To eliminate the shortage in expression of the flexibility and beauty of iron which seem impossible. SOLUTION: An iron pipe of 10 cm or under in diameter is cut to the length of 10 cm or under, and about 30 pieces of the cut iron pipes are welded in an irregular and three-dimensional manner, and overlapped on each other. Any smaller parts and inner parts of the iron pieces can be melted by carefully melting the overlapped iron pipes by the gas of oxygen and acetylene, and a finished product looks like a true coral.
