摘要
针对1Cr18Ni9Ti不锈钢薄板缝的脉冲激光焊接进行了研究。研究结果表明,焊缝熔深与激光功率呈线性关系;0离焦时适合1Cr18Ni9Ti不锈钢薄板的激光焊接参数范围为:脉宽2-10ms,功率0.5-2kW,在此参数范围内焊缝无飞溅。当功率大于2kW时,可通过调节负离焦量控制焊缝飞溅。
The pulsed laser welding of 1Cr18Ni9Ti stainless steel sheet seam was studied. The results show that there is a linear relationship between weld penetration and laser power, and the range of laser welding parameters suitable for 1Cr18Ni9Ti stainless steel sheet at 0 negative focal shift is: pulse width 2-10 ms, power 0.5-2 kW, and there is no spatter in the range of these parameters. When the power is greater than 2 kW, the weld spatter can be controlled by adjusting the negative focal shift.
