The welding strength is given effects in terms of different parameters: protruded length, surface roughness, welding time, welding stress, and the ultrasonic parameters which have been preset.
Because the perpendicularity of the IPS vibrating direction and welding stress setting direction minor chains of IPS and WP can osculate each other.
It is known commonly that the heat caused by the friction at the interface enhances with the welding time increasing under a certain welding stress.
With the string, pulley and weight unit, desired welding stress can be set and modified easily.
The experimental welding stress is set at a low level of 0.
Desired welding surfaces of workpieces are prepared with kinds of abrasive paper(#80-#100), so as to experiment under the same welding stress.
To this weld method, it is unadvisable to work under a lower welding stress and ultrasonic vibrating for long time.
The effect of welding stress on welding strength and welding area are shown in Fig.
Following an introductory chapter, part one focuses on understanding welding stress and distortion, with chapters on such topics as computational welding mechanics, modelling the effect of phase transformations on welding stress and distortion and using computationally efficient reduced-solution methods to understand welding distortion.
