Abstract

An apparatus and method of manufacturing a wire mesh laminate includes wrapping a central core with multiple layers of mesh screen and a barrier layer having a higher melting point than the mesh screen to form a spool assembly. The spool assembly is then surrounded by an outer cover and is heated to sinter or fuse together the layers of mesh screen.

Claims (60)

1. A method of manufacturing a mesh laminate screen, comprising:

wrapping a plurality of mesh layers and a barrier layer around a central core to form an assembly, wherein the barrier layer comprises a material having a higher melting point than the plurality of mesh layers;

heating the assembly; and

forming the mesh laminate screen.

2. The method of claim 1 , further comprising restraining expansion of the assembly.

3. The method of claim 2 , wherein restraining expansion of the assembly comprises disposing a cover around the assembly.

4. The method of claim 3 , wherein the cover comprises a material having a relatively low coefficient of thermal expansion.

5. The method of claim 3 , wherein the cover comprises a first portion coupled to a second portion.

6. The method of claim 5 , wherein the first portion is coupled to the second portion using one or more bolts.

7. The method of claim 3 , wherein an inner diameter of the cover is smaller than an outer diameter of the assembly.

8. The method of claim 1 , further comprising disposing a second barrier layer around the central core before wrapping the plurality of mesh layers.

9. The method of claim 8 , further comprising surrounding the assembly with a third barrier layer.

10. The method of claim 9 , further comprising banding the third barrier layer around the assembly.

11. The method of claim 10 , further comprising surrounding the banded assembly with a fourth barrier layer.

12. The method of claim 9 , wherein one or more of the barrier layers comprises a material having a higher melting point than the plurality of mesh layers.

13. The method of claim 1 , wherein the central core comprises a material having a relatively high coefficient of thermal expansion.

14. The method of claim 13 , wherein the central core has a higher coefficient of thermal expansion than a coefficient of thermal expansion of the cover.

15. The method of claim 1 , wherein the plurality of mesh layers comprise stainless steel.

16. The method of claim 15 , wherein the barrier layer comprises a material selected from the group consisting of molybdenum, tungsten, ceramic, and combinations thereof.

17. The method of claim 15 , wherein the assembly is heated between about 2,150° F. to about 2,350° F.

18. The method of claim 1 , wherein the assembly is heated between about 70% to about 90% of the melting point of the plurality of mesh layers.

19. The method of claim 1 , wherein the assembly is heated in a heating atmosphere selected from the group consisting of a gas, a gas mixture, a vacuum, and combinations thereof.

20. The method of claim 1 , wherein the assembly is heated in a heating atmosphere having a gas selected from the group consisting of hydrogen, nitrogen, and combinations thereof.

21. The method of claim 1 , wherein the central core comprises one or more perforations.

22. The method of claim 1 , further comprising fusing the plurality of mesh layers together.

23. A method of manufacturing a sintered mesh laminate, comprising:

surrounding a first barrier layer around a central core;

wrapping a plurality of mesh layers and a second barrier layer around the central core;

disposing a cover around the plurality of mesh layers and the second barrier layer, wherein the first and second barrier layers comprise a material having a higher melting point than the mesh layers; and

heating the cover and the plurality of mesh layers.

24. The method of claim 23 , wherein the central core is expanded upon heating.

25. The method of claim 24 , wherein the expansion exerts a pressure against the plurality of mesh layers.

26. The method of claim 25 , wherein the plurality of mesh layers is at least partially fused together.

27. The method of claim 23 , wherein the cover and the spool assembly are heated in a heating atmosphere selected from the group consisting of a gas, a gas mixture, a vacuum, and combinations thereof.

28. The method of claim 23 , wherein the cover and the plurality of mesh layers are heated between about 2,150° F. to about 2,350° F.

29. The method of claim 23 , wherein the cover and the plurality of mesh layers are heated between about 50% to about 95% of the melting point of the plurality of mesh layers.

30. The method of claim 23 , wherein the cover and the plurality of mesh layers are heated between about 70% to about 90% of the melting point of the plurality of mesh layers.

31. A method of manufacturing a mesh laminate, comprising:

wrapping a plurality of mesh layers and a barrier layer around a central core to form an assembly;

wherein the barrier layer comprises a material having a higher melting point than the plurality of mesh layers;

heating the assembly; and

forming the mesh laminate.

32. A method of manufacturing a mesh laminate, comprising:

wrapping a plurality of mesh layers and a barrier layer around a central core to form an assembly;

heating the assembly;

forming the mesh laminate;

disposing a second barrier layer around the central core before wrapping the plurality of mesh layers; and

surrounding the assembly with a third barrier layer.

33. The method of claim 32 , further comprising banding the third barrier layer around the assembly.

34. The method of claim 33 , further comprising surrounding the banded assembly with a fourth barrier layer.

35. The method of claim 32 , wherein one or more of the barrier layers comprises a material having a higher melting point than the plurality of mesh layers.

36. A method of manufacturing a mesh laminate screen, comprising:

forming an assembly comprising;

disposing a first barrier layer around a central core;

wrapping a plurality of mesh layers and a second barrier layer around the central core;

surrounding the central core with a third barrier layer;

heating the assembly; and

forming the mesh laminate screen.

37. The method of claim 36 , further comprising surrounding the banded assembly with a fourth barrier layer.

38. The method at claim 36 , wherein one or more of the barrier layers comprises a material having a higher melting point than the plurality of mesh layers.
