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.
