Laser-transmissible composition and method of laser welding |
摘要 |
A laser-transmissible composition comprises: a dynamic crosslinking polyolefin thermoplastic elastomer that has a melting point ranging from 160 to 210 degrees Centigrade in case of non-coloring, and dye salt exhibiting transmission of a laser having a wavelength of 800 to 1200 nm. A method for laser welding comprises: putting a laser-transmissible molded workpiece 1 made from the laser-transmissible composition onto a laser-absorptive molded workpiece 2 having a laser-absorbent 7, irradiating laser 3 towards the laser-transmissible molded workpiece 1 to weld the laser-transmissible molded workpiece 1 and the laser-absorptive molded workpiece 2. |
