摘要
针对超薄铝合金箔片(0.18mm)进行了光纤激光高速焊接试验研究,分析了影响光纤激光焊接效果的主要因素。通过对铝合金光纤激光焊接特性的分析,得出焊接头的准直镜与聚焦镜的焦距等对焊接接头形貌有着重要的影响的结论。在适宜的焊接工艺参数下,光纤激光焊接接头上、下表面焊缝形貌平整连续,焊缝一致性良好,拉力足够。
Experimental study on fiber laser high-speed welding of Ultrathin aluminum alloy foil（0.18mm）is carted out, and the main influencing factors on fiber laser welding are analyzed..Through analyzing fiber laser welding performance of superthin- aluminum alloy foil, it is concluded that the focal length of the focusing lens has great influ- ence on the morphology of welding joint. Under the proper welding condition, the weld bottom surface are even and continuous. They are of high quality and conformability and topography of top surface and enought tensile strength.
