Amorphous (PC + ABS) polymers are welded using ultrasonic welding process which is the aim of this investigation. Polymer granules are molded into rectangular plates with energy director embedded onto it before welding of polymer specimens. Taguchi method is employed to design the welding parameters in this investigation. Differential scanning calorimetric (DSC) and thermogravimetric analysis (TGA) are performed to examine the thermal behavior of the welded specimens. Weld strength of the polymers is determined using the mechanical testing. Finite element and microscopical analysis are also reported in this study. In the end, RSM and ANOVA techniques are applied and presented.
