摘要: In a method of the present invention for manufacturing a welded clad steel tube, an alloy including a corrosion-resisting or heat-resisting alloy is overlaid on a raw steel tube to manufacture a cold steel tube. Then, a cold or warm working is subjected to the clad steel tube. The clad steel tube is subjected to a heat treatment at a temperature exceeding a recrystallization temperature of the alloy.
