Abstract

In this work five different laser sources, three different CO₂ lasers, a ND-YAG and an High Power Diode Laser (H.P.D.L.) have been used to evaluate the joining quality of PE, PP and PC both in thin films (from 0.01 to 0.1 mm thick) and rigid sheets (from 2 to 5 mm thick), as well as in particular lap joints (thin films on rigid sheets). Joining process parameters, such as laser power level, welding speed, pressure and type of covering gas, focusing lens, different joint types, using similar or different polymers, have been analyzed to investigate their influence on the quality of the obtained joints.
