“…Their proposed solution involves using a femtosecond laser to join Al6082 and SiO2, aiming to reduce material surface roughness and enhance bonding strength. Li et al [7] contributed to improving joint strength in laser transmission welding by validating a laser surface treatment for titanium alloy. Their approach, involving local oxidation of the metal surface, resulted in a significant fivefold increase in welding strength when joining high borosilicate glass with titanium alloy.…”

“…Their analysis, utilizing scanning electron microscopy and x-ray diffraction, revealed that the joining mechanism primarily involved mechanical mixing between the two materials. Ji et al [7] demonstrated innovative laser welding of dissimilar glass and Kovar without optical contact. Their results showed that a femtosecond laser irradiated the Kovar alloy's surface, generating micro/nano particles that created strong adhesion between the two materials.…”

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.

Devices consisting of glass and metal are widely applied to many fields. With the miniaturisation and the expansion of application fields of these devices, the requirement of micro-joining between glass and metal is becoming higher. In this work, silica glass and 304 stainless steel were welded by the infrared nanosecond fibre laser. The welding quality was optimised by varying the laser parameters. The joint strength reached 16.39 MPa. The mechanism of the welding between the two materials was investigated. The results demonstrated the elemental diffusion in the interface between silica glass and 304 stainless steel under laser heating, where Fe, Cr and Si were the crucial factors in forming the welds. During the elemental diffusion, Cr was much easier to diffuse into glass than Fe. In the interface, Fe-O-Si bonds were observed. Moreover, increasing Cr content in the interface is a probable approach to improve the joint strength.

In this study, we conducted an investigation into the heterogeneous bonding process of glass and copper using a nanosecond pulsed laser for laser transmission welding. Our research focused on examining various processing parameters and the influence of focal plane positions on bonding quality. To evaluate weld strength, we employed both pull-tensile separation force (PTSF) and shear-tensile separation force (STSF) measurements. The analysis of fracture and separation results encompassed detailed examinations of weld morphology, microstructure, elemental composition, and phase configuration. The results revealed that increasing the laser welding energy initially enhanced the weld strength until it reached a saturation point. This saturation point was attributed to the formation of voids or cracks, leading to residual stress within the weld zone due to non-uniform hot spots in the molten area during processing. Among the different focal plane positions tested, positioning it below the glass/copper interface yielded the highest weld strength. The maximum achieved bond strength was above 10 MPa, demonstrating the feasibility of cost-effective pulsed laser welding for copper-to-glass applications. Furthermore, the welds exhibited superior resistance to STSF compared to PTSF. PTSF caused breaking at the weld seam-glass boundary, leaving the weld seam on the copper plate, whereas STSF resulted in separation along the weld-copper interface, leaving the weld seam on the glass sheet. In-depth analysis through SEM and EDS elucidated that Cu and SiO2 underwent intra-mixing and inter-particle diffusion in the molten pool during welding. HR-TEM and SAED observations unveiled the presence of polycrystalline copper nanoparticles, copper oxides, and an amorphous Cu-O-Si region at the weld interface. This amorphous region significantly contributed to the robust bonding between copper and glass.
