文章采用脉冲激光焊机针对Al-27Si进行了表面脉冲激光熔敷焊接试验，通过调整焊接电流、焊接速度、激光脉宽和激光频率，系统分析研究各种激光焊接参数对焊缝表面成型质量和横截面形状尺寸的影响规律。实验结果表明，提高焊接电流、激光脉冲宽度和频率，均能增加焊接热输入，从而增加焊接熔深；增大焊接速度，焊缝熔深减小，鱼鳞状波纹宽度增大。综合分析，在焊接电流90A、激光脉宽2ms、频率30Hz、焊接速度200mm/min的焊接规范下，能够得到较好的焊接接头。

The paper highlighted the pulsed laser-cladding welding test for joining of Al-27Si; it analyzed the effects of various welding parameters on weld surface quality and weld pool shape. The results showed that welding heat input increased with the increase of welding current, pulse width and laser frequency, thereby increasing weld penetration;weld penetration decreased and inter-ripple distance increased with the increase of welding travel speed. The paper pointed out that improved weld joint was available with welding current of 90A, pulsed width of 2ms, laser frequency of 30Hz and welding travel speed of 200mm/min.
