PURPOSE:To stabilize production by forming a clad blank by setting the size of a base metal in the specified range for the clad material, then by performing a rolling junction after heating by a pusher type continuous heating furnace. CONSTITUTION:The thickness T of the base metal 1 in case of producing a sandwich type clad steel sheet is taken in >=50mm and the width W, length L are set in the smaller size >=40mm respectively than the size of a clad material 2 as well. A clad blank B is then formed by performing a fillet welding in the state of the combination that the base metal 1 is recessed >=20mm to the inner side for the clad material 2. The clad steel sheet in then obtd. with the rolling junction of the blank B after its heating by a pusher type continuous heating furnace. The welding work can be facilitated and a beveling, etc., become unnecessary, and the rise phenomenon inside the heating furnace can be prevented as well. In this way, therefore, the clad steel sheet can be produced stably.
