Embodiment Construction
[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0037] refer to Figure 1 to Figure 3 As shown, an embodiment of the method for one-time welding of glass and metal of the present invention,
[0038] First of all, it is necessary to select glass and metal materials. In the selection requirements, the first factor is that the difference in thermal expansion coefficient between glass and metal should be small, so that the dimensional changes in the heating and cooling process are not much different without causing large stress. , the glass will not crack or separate from the metal; the second factor is to select the optical properties of the glass material according to the application needs to meet the needs of use; the third factor is...

Abstract
The invention discloses a method for one-time welding of glass and metal, which comprises the following steps: selecting materials first, selecting a Kovar alloy ring and glass with a small difference in thermal expansion coefficients, and then mixing the glass and Kovar alloy ring with anhydrous Ethanol and pure water were ultrasonically cleaned, dried and used; then, the Kovar alloy ring was placed on the graphite sheet, the glass was placed in the Kovar alloy ring, and the graphite sheet carrying the Kovar alloy ring and glass was placed in a high-temperature furnace. Put on the support frame and close the furnace door; finally, set the temperature and time of the high-temperature furnace, run the high-temperature furnace for high-temperature welding, and after the operation is completed and cooled to room temperature, the welded product can be obtained. The welding operation of the invention is simple and reliable, the welding yield is high, and the control is easy.
Description
technical field [0001] The invention relates to the technical field of welding, in particular to a method for one-time welding of glass and metal. Background technique [0002] Glass material has the characteristics of anti-oxidation, corrosion resistance, high temperature resistance, high hardness and wear resistance, and its application is more and more extensive; but the shortcomings of low ductility and impact toughness of glass itself hinder its wide application in engineering structures. Glass and metal connectors with high plasticity and toughness and strong impact resistance have been widely used in the manufacture of piezoelectric sensors and the packaging of deliquescence scintillation crystal materials for use in harsh working environments. [0003] However, glass has good chemical stability and is very different from metal materials, and there are great difficulties in connecting the two. Among them, the thermal expansion coefficients of glass and metal are quit...
