The Influence of Dynamics and Vibrational Characteristics on Weldability of Joining Metals Ultrasonically
Most of engineering processes are significantly affected due to changes in its dynamics and vibrational characteristics during operation. Such one of these processes is welding which the process is carried out on join metals by using suitable manner like welding by ultrasonic technique. The ultrasonic technique has ability to joint parts without need to use any aided, and then this allow the technique to become more reliable and applicable. The technique is mostly provide proper weld, but the weldability of joining similar parts may affects due to any change in vibrational characteristics during operation. This study presents the design, characterisation and test of a lateral-drive ultrasonic metal spot welding device. The ultrasonic metal spot welding horn is modelled using finite element analysis (FEA) and its vibration behaviour is characterised experimentally to ensure ultrasonic energy is delivered effectively to the weld coupon. The weldability is examined through examining weld strength using tensile-shear tests. The results show how the weldability is particularly sensitive to the combination of ultrasonic parameters such as welding force and displacement amplitude.
