“…In laser transmission jointing, the ideal material combination to be joined using this process includes one absorbent (in this case, titanium) and transparent (in this case, PET) part [12,13]. The laser energy penetrates the transparent part and is absorbed by the absorbing part, so that the heat is induced directly at the interface [14].…”

Laser transmission joint between biocompatible, dissimilar materials have the potential for application in biomedical and their encapsulation process. This paper is devoted to laser transmission joint between 0.1mm thick PET films and 0.1mm thick Titanium using near-infrared diode lasers. Response surface methodology (RSM) is used to develop mathematical models between the joining process parameters. The developed mathematical models are tested for adequacy using analysis-of-variance (ANOVA) method. In addition, the main effect of each parameter and the interaction effects with other process parameters are analyzed. Finally, the experimental results agree with those predicted indicate that the developed mathematical models can predict the responses adequately.

The technological and economic advantages of laser welding of plastics in comparison to the traditional welding process and research situation are analyzed in this paper. Process methods of this technology are reviewed as well as the range of application for these manners is compared. The technological challenges facing the further development of the technology and the critical issues needing to be solved are deeply investigated. It is pointed out that efficient prevention of plastics distortion and cracking as well as control of internal structure and defects are currently the two bottleneck obstacles challenging the further development and industrial applications of the revolutionary advanced manufacturing technology. The developments of laser welding technology of plastics in the future are also forecasted.

“…There are many influential process parameters on the weld quality of laser transmission joining, such as welding speed, laser power, spot diameter and so on. In the present, test methods are widely used in this area to research the interaction effect of process parameters on the joint quality [5][6][7][8], Experimental studies often take a long time and a large number of funds, whereas through finite element simulation all the process parameters can be taken into account to achieve optimum parameters, thus reducing test cost, shortening test cycles and improving efficiency. Many scholars have already researched finite element simulation of laser transmission joining process, such as finite element model of laser transmission joining process [9],temperature field distribution under conditions of different process parameters [10,11]and the residual stress distribution [12].…”

Laser transmission joining of dissimilar and biocompatible materials has potential applications in biomedical implants. In this work, a three-dimensional (3D) transient model for sequentially coupled thermal/mechanical analysis of laser transmission joining of 0.1mm thick PET film and 0.1mm stainless steel has been developed by using the ANSYS parametric design language APLD, along with a moving Gaussian laser heat source. It can be calculated how long it takes to reach the quasi-steady state through the stimulation of the temperature field. The calculated values of the joint width are in good agreement with the experimental results by comparison under conditions of different parameters, which indicates that the model is reliable and is helpful for optimizing process parameters. Then based on the temperature field, the residual stress field distribution on both PET and stainless steel surface is achieved by applying the indirect coupling methods to the analysis. this study also has laid a theoretical foundation for improving the stress distribution on the joint.
