A stack of two different metals to be welded, one of which is harder than the other, and an additional soft metal placed on the harder metal is placed between a pair of horn tips (grip members) of an ultrasonic welder. The harder metal is covered with a soft metal layer of a high plastic fluidity. Serrations are formed on the surface of the horn tips to grip the softer metal and the additional metal tightly during ultrasonic vibration is applied.
