To provide a method for joining clad steel by which welding speed is increased in the site-welding of the clad steel, and the toughness of a joint is improved.
The method is for joining the clad steel by which the mutual end faces of the clad steel 4 which includes laminated carbon steel layer 5 and clad layer 6 are butted and joined. The method includes a friction stir welding step where the clad layers 6 and the carbon steel layers 5 which are mutually opposed to each other are joined so that they may be stirred at the same time and, after that, an arc welding step where the unwelded portion between the mutual carbon steel layers which are situated in a position apart from the clad layers is welded from the side of the carbon steel layer by arc welding.
