摘要

本研究采用了一种新的表面预处理方法--激光表面重熔（LSR）。本实验旨在建立一套适合铝合金和玻璃在这种特定预处理下的激光焊接工艺参数。本实验探讨了激光焊接参数对高硼硅玻璃和铝合金焊接强度的影响。研究具体考察了四个工艺参数：散焦量、激光功率、频率和脉冲宽度对焊接结果的影响。结果表明，当离焦量为零（即激光汇聚在玻璃和金属的界面上），激光焊接参数设置为功率 250 W、焊接速度 1 mm/s、焊接频率 10 Hz 和脉冲宽度 2.5 ms 时，铝合金和玻璃之间的焊接质量达到最佳。实验还分析了不同参数下的断裂形态，总结了断裂的位置和原因，并确定了断裂位置与焊接强度之间的关系。

The Impact of Welding Parameters on the Welding Strength of High Borosilicate Glass and Aluminum Alloy

This study adopts a new surface pretreatment method, Laser Surface Remelting (LSR). This experiment aims to establish a set of laser welding process parameters suitable for aluminum alloy and glass under this specific pretreatment. This experiment explores the impact of laser welding parameters on the welding strength between high borosilicate glass and aluminum alloy. The study specifically investigates the effects of four process parameters: defocus amount, laser power, frequency, and pulse width on the welding outcome. The results indicate that the welding quality between the aluminum alloy and glass reaches its optimum when the defocus amount is zero (i.e., when the laser converges at the interface between the glass and the metal) and the laser welding parameters are set to a power of 250 W, a welding speed of 1 mm/s, a welding frequency of 10 Hz, and a pulse width of 2.5 ms. The experiment also analyzes the fracture morphology under different parameters, summarizing the locations and causes of fractures, and establishing the relationship between the fracture location and the welding strength.

期刊介绍： Metals (ISSN 2075-4701) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Metals provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of metals.
