| 摘 要： | 为了研究激光焊接中各工艺参量对高密度聚乙烯塑料焊接件性能的影响,采用激光穿透焊接高密度聚乙烯试样件,进行了力学拉伸试验并应用扫描电镜观测其焊缝断口的形貌.试验结果表明,当光斑直径为2mm、激光功率为75W、焊接速度为2mm/s时,焊接件断口没有飞边和夹渣,焊接接头成型良好,力学性能最佳:随着激光光斑直径的减小、焊接速度的降低或功率的增加,接头强度及伸长率均有提高.进一步从激光体能量角度分析了影响接头强度的因素,证实了激光焊接高密度聚乙烯是一种可行的方法.

| Abstract: | In order to study the effect of technical parameters on the performance of high density polyethylene (HDPE) plastic welding pieces,with laser permeating a weld HDPE workpiece,mechanical tensile test was carried out and the morphology of the joint fracture was observed with a scanning electron microscopy.Results show that the joint intensity and elongation property accrete with smaller light spot and welding velocity and larger laser power.The welding joint is good and mechanical property is best with laser spot diameter in 2mm,laser power at 75W and welding velocity at 2mm/s.It is proved that laser welding HDPE is a feasible. |
