[Principle of the Laser Plastic Welding]

In laser welding of thermoplastics, sometimes referred to as "laser transmission welding" or "through transmission IR welding" (TTIr), transparent and absorbing parts are bonded togethers.

The laser beam penetrates the transparent plastic and is converted to heat in the absorbing plastic. Since both parts are pressed together during the welding process, heat is conducted from the absorbing to the transparent plastic, allowing both materials to melt and create a bond. In addition to the externally applied clamping force and internal joining pressure is also generated through the thermal expansion of the laser-heated plastic parts. The internal and external joining pressure ensure strong welding of both parts.

Almost all thermoplastic plastics and thermoplastic elastomers can be welded with the laser beam - including ABS, PA, PC, PP, PMMA, PS, PBT as well as fiberglass reinforced plastic types. The achieved weld seam strength remains within the area of basic material strength.
