摘要
利用激光透射焊接技术对聚丙烯(PP)塑料进行焊接,研究了激光焊接热塑性塑料的可行性。通过正交试验法研究了激光功率、焊接速度、碳黑含量对焊接强度和焊接质量的影响。探讨了线能量对焊接强度的影响。结果表明:对PP 材料来说,激光功率是首要影响因素,其次是焊接速度,最后是碳黑含量。最佳的焊接工艺参数为激光功率50 W,焊接速度15 mm/s,碳黑质量分数0.15%。线能量对焊接质量有较大影响,线能量在1.5~3 J/mm 可得到较好强度的焊件。
Abstract
Polyprogylene (PP) plastic is welded by using laser transmission welding technology. Feasibility of laser welding PP plastics is discussed. The orthogonal experiment is applied to study the influence of laser power, welding speed and mass fraction of carbon black on the welding strength and welding quality. Effect of line energy on welding strength is discussed. The results show that the laser power is the primary influence factor, followed by the welding speed, the last is the mass fraction of carbon black. The best welding parameters for PP are laser power of 50 W, welding speed of 15 mm/s and mass fraction of carbon black of 0.15%. Line energy has an impact influence on welding quality. When line energy is in the range of 1.5~3 J/mm, the higher welding quality can be attained.
