Abstract
The present research manages through transmission laser welding (TTLW) of polycarbonate and acrylic, both being transparent, have been directed framing a lap joint. A 12-W Nd:YVO4 laser with 1064 nm wavelength has been used for the welding procedure. The effect of welding parameters, to be specific, scanning speed, laser power and laser frequency, has been analysed. The weld quality has been assessed by an ultimate load (UL). Response surface methodology (CCD) has been embraced for the experimental procedure. To correlate the welding parameters with a response, a quadratic model has been created. The analysis of variance method is used to find out the important parameter/s on specific response. A mathematical model has been used to optimize the ideal welding conditions to achieve the improved ultimate load. To validate the applied optimization technique, confirmatory tests have been performed.
