An ultrasonic cleaning system utilizes a manufacturing technique wherein one or more piezoelectric elements are fused, secured by a gold sputtering technique, or attached by electrochemical deposition to an associated metal surface, whether it be a metal cleaning tank or an electrode, by a gas-tight joint or connection, eliminating the necessity of utilizing conventional techniques that require bonding of the element or elements to the associated metal surfaces by epoxy compounds or the like. The novel technique is practiced, in some forms of the invention, by molding the piezoelectric elements integrally with ceramic materials utilized for the liquid cleaning tank itself, and thereafter polarizing the area or areas that are to be made piezoelectric. In other forms, a metal cleaning tank may be used, but in every instance the fusing of the piezoelectric mixture to the tank walls and/or electrodes is accomplished during the firing of the ceramic material of which the piezoelectric element is formed.
