ABSTRACT:
Placing a clad plate, comprising a resistor having a specific resistance at least two times that of aluminum, between two aluminum plates or between an aluminum plate and non-aluminum plate metal plate to be welded, and supplying an electric current through the aluminum plates to be welded and the clad plate. The clad plate itself may have aluminum plates sandwiching the resistor, the thickness each of the aluminum plate of the clad plate is from 1/4 to 6 times that of the resistor. The resistor can be made of iron, steel, titanium, tantalum, nickel, zirconium, and alloys thereof.
