Laser welding of plastic parts

The assembly of plastic parts is made most of the time by “transparency”. The first piece of plastic is transparent to the laser beam whereas the second plastic is absorbing it. There is a heating by thermal conduction, fusion then welding of the two plastic parts.The automotive industry uses this kind of process for the assembly of headlights and sometimes moving parts like the trunk hatch.
