Technical Study on Nanosecond Laser Welding of Stainless Steel and Aluminum Alloy
摘要
采用Raycus纳秒激光器对0.2 mm的301不锈钢和0.2 mm的6063铝合金进行叠焊工艺研究。焊接方式为点焊, 图形为螺旋线, 影响纳秒激光点焊接性能的主要参数有波形、脉冲频率、平均功率、速度和螺旋线间距, 对这五因素进行正交试验, 使用直观分析法和方差分析法, 验证这五个因素对焊点拉力和余高的影响程度。结果表明, 其焊点余高的影响因素由主到次依次为波形、脉冲频率、平均功率、速度和螺旋线间距; 对焊点拉力的影响因素由主到次为平均功率、脉冲频率、波形、速度和螺旋线间距。并且通过正交试验方法, 可以找到更多更佳的焊接参数。
Abstract
A Raycus nanosecond laser was used to technical study the stitch welding of 0.2 mm 301 stainless steel and 0.2 mm 6063 aluminum alloy. The welding method is spot welding and the pattern is spiral. The main parameters that affect the nanosecond laser spot welding performance are waveform, frequency, average power, speed and spiral line spacing. The orthogonal tests of these five factors were carried out to verify the influence of these five factors on the tensile force and residual height of the solder joints by using visual analysis and variance analysis. The results show that the influencing factors on the residual height of the solder joints from the primary to secondary are waveform, pulse frequency, average power, speed and spiral line spacing, the influencing factors on the tensile fore of the solder joints from the primary to secondary are average power, pulse frequency, waveform, speed and spiral line spacing. And through the orthogonal test method, more and better welding parameters can be found.
