FORWARD TO BETTER UNDERSTANDING OF OPTICAL CHARACTERIZATION AND DEVELOPMENT OF COLORED POLYAMIDES FOR THE INFRA-RED/LASER WELDING: PART I - EFFICIENCY OF POLYAMIDES FOR INFRA-RED WELDING

摘要

The influence of a wide range of the infrared (IR) wavelengths (from 830 to 1,064 nm) on the optical properties of welded thermoplastics was evaluated for unfilled, filled and reinforced polyamide 6, 66 and amorphous grades. Presented results and developed recommendations will help, designers, technologists and materials scientists in welded parts design, materials selection and new materials development for various laser welding (LW) applications.
