Innovations in Laser Welding of Thermoplastics: This Advanced Technology is Ready to be Commercialized 2002-01-2011

Previously we reported to the SAE 2000 basics in selection of various colored and un-colored/natural nylon 6 (polyamide - PA 6) based plastics for laser welding technology. Later we presented to Antec¹ 2001 and to SAE 2002 our developments of colored in black through-transmissible grades of PA 6 plastics, which were specially tailored for the specifics of the design and laser welding technology. In this current paper, we will try to enhance the understanding of the engineering community regarding the usefulness and applicability of laser welding technology, developed colored thermoplastics, and its increasing use in various automotive and transportation applications.
