Abstract

A method of making an ultrasonic amplifier (8) comprises shaping the ultrasonic amplifier (8) by forging. This means that an amplifier with a complex shape can be forged in one piece, preventing weaknesses at the joins between different sections of the amplifier. It greatly increases the fatigue resistance of the amplifier (8) and can increase the effectiveness of the amplification.

Claims

1. A method of making an ultrasonic amplifier comprising

shaping the ultrasonic amplifier by forging.

2. A method according to claim 1 involving multiple forging operations.

3. A method according to claim 1 including

finishing the ultrasonic amplifier by a machining operation.
