摘要

    摘要
  • 摘要: 研究聚甲基丙烯酸甲酯(PMMA)塑料与304不锈钢激光焊接热传导技术，采用正交试验法分析聚甲基丙烯酸甲酯和304不锈钢之间的焊接质量. 对焊接后的试样进行拉伸测试和切片试验，用能量密度定量判定焊接结果，分析多种焊接因素对抗拉强度和焊缝宽度的影响. 利用正交试验极差分析法对试验数据进行处理，获得透明聚甲基丙烯酸甲酯和304不锈钢之间激光热传导焊接的最佳焊接工艺参数. 结果表明，焊接因素对焊接强度的影响从大到小的顺序为焊接速度、脉冲宽度、保护气体流量、峰值功率、光斑直径和脉冲频率.
    Abstract: Polymethyl methacrylate (PMMA) and 304 stainless steel were welded by laser heat conduction joining technique, and welding quality between transparent PMMA and 304 stainless steel was investigated by orthogonal test method. Tensile test and section test were carried out, and welding results were quantitatively determined by energy density. The effects of various welding factors on tensile strength and weld width were analyzed. Experimental data were processed by the difference analysis method of orthogonal test, and optimal welding parameters of laser heat conduction welding between PMMA and 304 stainless steel were achieved. The results showed that the welding speed was the most dominant factor in determining the joint strength, and the pulse width, gas protection volume, peak power, spot diameter and pulse frequency were the 2nd to 6th effective factors.
