Three Major Joint Design Characteristics In order to obtain acceptable, repeatable welded joints, three general design guidelines must be followed: 1. Ultrasonic welding is a very fast and energy-efficient technique for the joining of thermoplastic composites. for plastic. The influence of each parameter is assessed by temperature measurement and mechanical tests on US welding specimens. 2nd ed. Since no bulk heating of the work pieces is involved, there is no danger of any mechanical or metallurgical bad effects. Pressure is applied to keep the horn in contact with the welded materials and to hold them together. For 50 years, ultrasonic welding of plastics has relied on a simple "weld-by-time" method of process control (see Fig. . There are five main parameters that Cold temperature compatibility Poor to excellent need to be considered with in producing good quality ultrasonic welding which are weld pressure, weld time, hold time, down speed and amplitude.

The initial contact area between the mating surfaces should be small to concentrate and decrease the total energy (and thus the time) needed to start and complete melting. Characteristics Of Ultrasonic Welding: It is a solid-state welding process. The ultrasonic welding of metals has a few advantages compared to conventional welding methods such as gas metal arc welding: Ultra fast: The entire process lasts for mere split seconds. ultrasonic welding parameters result in different temperature rises at joints, which consequently result in different deformations and bond qualities at the interfaces of the aluminium strands. 33 a major advantage of this technology is that it is fast, economic to use in That mechanical vibration, which along with applied force, cre- Handbook of Plastic Joining: A Practical Guide.
