Laser spot welding of thermoplastic and ceramic: An experimental investigation

Laser welding of dissimilar materials classes has vast potential in a variety of applications due to the non-contact nature of the process. This study investigates the effects of CO2 laser process parameters on the characteristics of spot welded joint between ceramic and thermoplastic. Using a full-...
