| Abstract: | The transmission welding test of the same kind of polycarbonate(PC)transparent plastic plate was carried out using a 1910 nm semiconductor laser without the addition of absorbent.The influence of parameters,such as,laser power,welding speed and line energy on the welding effect of the test piece was analyzed,and the process parameters of the test piece with ideal welding effect were determined.The results show that the best line energy is 2.5 J/mm.The specimen obtained under this linear energy has regular morphology,large tensile force and ideal welding effect.Keeping the optimal line energy constant,the welding effect of multiple sets of test pieces obtained by changing the laser power and welding speed is basically the same.When the welding power is 30 W,the welding speed can reach 12 mm/s and the welding effect is ideal. |
