The present invention relates to a method for manufacturing at least one portion of a seal ensuring gas-tightness between at least one first and one second glass panel in a glazing system, the method including the following steps: depositing a first adhesive layer on a first peripheral area of the first panel and a second adhesive layer on a second peripheral area of the second panel; welding a first metal seal element to the first adhesive layer; welding a second metal seal element or said first metal seal element to the second adhesive layer. According to the invention, the first and second adhesive layers are deposited using a high-speed oxy-fuel flame-spraying method.

1. A process for manufacturing at least a portion of a seal between a first glass panel and a second glass panel in a glazing, the process comprising: depositing a first adhesion layer onto a first peripheral zone of the first panel and a second adhesion layer onto a second peripheral zone of the second panel;welding a first metal seal element to the first adhesion layer; andwelding a second metal seal element or the first metal seal element to the second adhesion layer;wherein depositing the first and second adhesion layers comprises a high-velocity oxy-fuel flame-spraying process;wherein the depositing the first and second adhesion layers is in an atmosphere at atmospheric pressure;welding the first metal seal element to the first adhesion layer is in an atmosphere at atmospheric pressure;the process comprises welding a second metal seal element distinct from the first metal seal element to the second adhesion layer in an atmosphere at atmospheric pressure; andthe process further comprises welding the first metal seal element to the second metal seal element in an atmosphere at reduced pressure or under vacuum. 2. The process of claim 1, further comprising: depositing a metal solder layer onto at least a portion of the first adhesion layer, the second adhesion layer, or both,wherein a weld of the first metal seal element, the second metal seal element, or both is a fusion weld of the metal solder layer. 3. The process of claim 1, wherein at least a portion of the welding is ultrasonic or induction welding. 4. The process of claim 1, comprising welding a second metal seal element to the second adhesion layer, wherein the process further comprises welding the first metal seal element to the second metal seal element. 5. The process of claim 1, further comprising: exposing the first adhesion layer, the second adhesion layer, or both to a carburising flame before welding to that adhesion layer. 6. The process of claim 1, wherein the first and second adhesion layers each comprise at least one adhesive material selected from the group consisting of copper, copper alloy, aluminum, aluminum alloy, iron, iron alloy, platinum, platinum alloy, titanium, titanium alloy, tin, and tin alloy. 7. The process of claim 1, wherein the first and second adhesion layers each comprise an adhesive material that has a coefficient of thermal expansion of 3 to 23.10−6 K−1. 8. The process of claim 1, further comprising: exposing the first adhesion layer, the second adhesion layer, or both to a soldering flux before welding, before depositing a metal solder layer, or before both. 9. The process of claim 1, wherein the first metal seal element, the second metal seal element, or both, comprises a metal weld layer prior to welding to the first or second adhesion layer. 10. The process of claim 1, wherein the first and second metal seal elements each comprise at least one material selected from the group consisting of copper, copper alloy, aluminum, aluminum alloy, iron, and iron alloy. 11. The process of claim 1, wherein the first and second metal seal elements, an adhesive material of the first and second adhesion layers, or both comprise an iron alloy comprising iron in a content of 53-55% wt., nickel in a content of 28-30% wt., and cobalt in a content of 16-18% wt. 12. The process of claim 1, wherein the high-velocity oxy-fuel flame-spraying process employs a spraying assembly comprising a first inlet, a second inlet, a third inlet, and an outlet,wherein the first, second, and third inlets lead to a combustion chamber,and wherein the high-velocity oxy-fuel flame-spraying process comprises:injecting, under pressure, a fuel and oxygen through the first inlet;injecting an adhesive material into the second inlet;combusting the fuel and the oxygen, thereby melting the adhesive material in the combustion chamber;injecting a gas under pressure through the third inlet of the spraying assembly, thereby enabling spraying of the molten adhesive material from the assembly via the outlet at a supersonic speed; andorienting the outlet of the assembly towards a peripheral zone, thereby enabling formation of an adhesion layer. 13. The process of claim 12, wherein an angle between an axis of the outlet and the glass panel is from 45° to 90°. 14. The process of claim 12, wherein the high-velocity oxy-fuel flame-spraying process comprises moving the spraying assembly and the glass panel relative to one another at a speed of from 5 to 30 m/min. 15. The process of claim 1, wherein the first and second peripheral zones of the first and second panels are on a respective edge of the first and second panels. 16. The process of claim 13, wherein the angle between the axis of the outlet and the glass panel is from 70° to 90°. 17. The process of claim 14, wherein the high-velocity oxy-fuel flame-spraying process comprises moving the spraying assembly and the glass panel relative to one another at a speed of from 5 to 20 m/min. 18. The process of claim 1, wherein the glazing is a vacuum glazing.
