Abstract

This study investigates the relationship between a material’s ablation threshold and the quality of metal-to-glass weld. Our analysis demonstrates that materials with lower ablation thresholds demand less radiation energy for achieving maximum shear stress, indicating a potential link to the quality of metal-to-glass welds. The findings suggest that Alloy 36, due to its high ablation threshold and relatively low melting temperature, holds promise for enabling stronger and more enduring metal-to-glass connections. In the present work, a weld resistant to shear stress up to 5MPa was achieved with Alloy 36 and both fused silica and borosilicate glass. The latter holds promise for industrial exploitation due to the very similar coefficient of thermal expansion between the glass and the metal.
