ABSTRACT:
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 workpiece1made from the laser-transmissible composition onto a laser-absorptive molded workpiece2having a laser-absorbent7,irradiating laser3towards the laser-transmissible molded workpiece1to weld the laser-transmissible molded workpiece1and the laser-absorptive molded workpiece2.
