“…CO 2 lasers have the highest wavelength at 10 600 nm 2,3. The Nd:YAG and diode lasers come very close to each other in terms of their properties at 1 064 nm and 800 to 1 000 nm, respectively 4. Between these and the CO 2 laser we have the so‐called “2μ” laser with a wavelength of 2 000 nm 5.…”

This article has been compiled on the basis of the many years' experience that has been acquired in the field of plastics welding by the Institute of Plastics Engineering (KTP) at the University of Paderborn. A brief report is given on the state of the art in laser and microwave welding technology. An overview is also included on the potential and limits of the use of laser and microwave welding in plastics processing. In the case of laser welding, a number of results achieved in welding of molded parts are presented that have been obtained in the course of extensive investigations. For microwave welding, a report is included on investigations that are currently running at the KTP. In addition to this, details are given on the basic suitability of laser and microwave welding for joining films and sheetings.

“…The energy is taken up directly by the carbon atoms in the molecule chains. The penetration depth of this type of laser in plastic is thus very low, attaining a maximum of 0.5 mm depending on the material 4…”
