Abstract

We report an ultra-short-pulse laser welding process that allows one to consistently weld Borofloat 33 glass to aluminum with a shear strength above 50 MPa. We explored the morphology of the welding seam and quantified the quality of the bonding by statistically determining the shear strength with more than 30 samples. The results of the shear strength tests indicate that the intrinsic shear strength of the aluminum serves as the upper limit of the glass-to-metal bond.

摘要

我们报道了一种超短脉冲激光焊接工艺，该工艺能够始终如一地将硼硅酸盐33玻璃焊接到铝上，其剪切强度超过50兆帕。我们探究了焊缝的形态，并通过对30多个样品的剪切强度进行统计测定来量化结合质量。剪切强度测试结果表明，铝的固有剪切强度是玻璃与金属结合的上限。
