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.
為瞭研究激光銲接中各工藝參量對高密度聚乙烯塑料銲接件性能的影響,採用激光穿透銲接高密度聚乙烯試樣件,進行瞭力學拉伸試驗併應用掃描電鏡觀測其銲縫斷口的形貌.試驗結果錶明,噹光斑直徑為2mm、激光功率為75W、銲接速度為2mm/s時,銲接件斷口沒有飛邊和夾渣,銲接接頭成型良好,力學性能最佳:隨著激光光斑直徑的減小、銲接速度的降低或功率的增加,接頭彊度及伸長率均有提高.進一步從激光體能量角度分析瞭影響接頭彊度的因素,證實瞭激光銲接高密度聚乙烯是一種可行的方法.

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.
