Abstract

Optimization of weld width and tensile strength in pulsed Nd: YAG laser welded Hastelloy C-276 sheets, subjected to varied welding speed (350-450 mm/min), pulse energy (10-14 J) and pulse duration (6-8 ms), is attempted. Experimental conditions are designed based on Taguchi L9 orthogonal array. The parameters for attaining a minimum weld width and maximum tensile strength were determined by computing the Signal-to-Noise ratio. Further, a mathematical model is developed for determining the weld width and tensile strength of the weld, based on the regression analysis using statistical software MINITAB-16 and the level of fit are determined by analysis of variance.
田口法优化哈氏合金板材激光焊接工艺参数
在不同的焊接速度(350-450 mm/min)、脉冲能量(10-14 J)和脉冲持续时间(6-8 ms)下,尝试优化脉冲Nd: YAG激光焊接哈斯特洛伊c -276板的焊缝宽度和抗拉强度。基于田口L9正交阵列设计了实验条件。通过计算信噪比确定了获得最小焊缝宽度和最大抗拉强度的参数。基于MINITAB-16统计软件的回归分析,建立了确定焊缝宽度和焊缝抗拉强度的数学模型,并通过方差分析确定了拟合水平。
