摘要
Abstract
The weld test of 2.5 mm thick 6061 aluminum alloy is done by the 5 kW optical fiber laser beam. The effect of laser power and weld speed on weld appearance of Al alloy is investigated. The weld surface shape is compared with the weld cross-sectional shape. The flow behavior of the melt pool during the welding process is discussed. The results reveal that laser power and weld speed have a remarkable influence on weld depth and width. In a certain rang, the weld width increases with the increasing laser power, but the weld width can only reach to a certain value. The value of laser power affects its own stability and the appearance of weld.关键词
