利用300 W Nd:YAG毫秒量级脉冲激光器对6061铝合金与玻璃进行激光透射焊接实验。利用万能拉伸实验机测量焊接件拉断力，用扫描电子显微镜观察玻璃断口及焊缝横截面形貌。研究焊接道次和焊缝间距对焊接件拉断力、焊缝形貌以及断口形貌的影响。研究表明，利用毫秒级脉冲激光可实现玻璃与铝合金的可靠焊接，焊接件拉断力最大可达159.93 N。焊缝间距为0.8 mm时，铝合金与玻璃能充分混合，获得较好的焊接。

An experimental study on laser transmission welding of transparent glass and 6061 aluminium alloy by a millisecond pulsed 300 W Nd:YAG laser is reported. The test of breaking strength is conducted by a universal tensile test machine, and the glass fracture morphology and weld sectional microstructure are analyzed by scanning electron microscopy. The effect of multipass welding and weld spacing on weld seam morphology, breaking strength, and fracture morphology is studied. The results indicate that a good glass-to-aluminium joint can be obtained if a millisecond pulsed laser is used. The maximum breaking strength of weldments is 159.93 N. When the distance between the welding seams is 0.8 mm, the aluminium alloy and glass can obtain good sealing.
