An electromagnetic interference shielded panel and method of manufacture. The panel includes one or more frame members having a rib adapted to provide sacrificial material when a first skin member is welded to the frame member. The first skin member is welded to the frame members of a frame assembly prior to bonding of a core member and a second skin member to the first skin member and frame assembly.

What is claimed is: 1. A frame member for use with a skin member in forming an electromagnetic interference shielded panel, said frame member comprising: a base wall extending between a first end and a second end; a first side wall extending between a first end and a second end, said first end of said first side wall attached to said first end of said base wall, said first side wall including a first surface extending from a first end to a second end, a lip extending outwardly from said second end of said first surface to an outer end, said first surface and said lip forming a first recess, a second surface extending from a first end to a second end, said first end of said second surface located adjacent said outer end of said first lip, and a third surface extending between a first end and a second end, said second end of said third surface being located adjacent said second end of said second surface, said third surface being located outwardly from said second surface such that a second recess is formed by said second and third surfaces, and an elongated rib extending outwardly from said second surface of said first side wall; a second side wall extending between a first end and a second end, said first end of said second side wall attached to said second end of said base wall, said second side wall being spaced apart from and generally parallel to said first side wall; whereby said rib provides sacrificial material for welding the skin member to said first side wall of said frame member. 2. The frame member of claim 1 wherein said rib is located adjacent said first end of said third surface and extends outwardly from said third surface. 3. The frame member of claim 1 including an end wall extending between a first end and a second end, a first inclined wall extending between said second end of said first side wall and said first end of said end wall and a second inclined wall extending between said second end of said second side wall and said second end of said end wall. 4. The frame member of claim 1 wherein said rib is located more closely to said second end of said first side wall than to said first end of said first side wall. 5. The frame member of claim 1 wherein said rib extends outwardly from said second surface of said first side wall approximately 0.05 inch. 6. The frame member of claim 5 wherein said rib has a width of approximately 0.05 inch. 7. The frame member of claim 1 wherein said rib extends from a first end of said frame member to a second end of said frame member. 8. The frame member of claim 1 wherein said first recess of said first side wall is adapted to receive a barrier member. 9. The frame member of claim 1 wherein said second recess of said first side wall is adapted to receive the skin member. 10. The frame member of claim 1 wherein said rib extends outwardly from said third surface of said first side wall. 11. A frame member for use with a skin member in forming an electromagnetic interference shielded panel, said frame member comprising: a base wall extending between a first end and a second end; a first side wall extending between a first end and a second end, said first end of said first side wall attached to said first end of said base wall, said first side wall including a first surface extending from a first end to a second end, a second surface extending from a first end to a second end, said second surface being located outwardly from said first surface, an elongate rib extending outwardly from said first end of said second surface, and a first recess formed by said rib and said first surface; a second side wall extending between a first end and a second end, said first end of said second side wall attached to said second end of said base wall, said second side wall being spaced apart from a generally parallel to said first side wall; whereby said rib provides a sacrificial material for welding the skin member to said first side wall of said frame member. 12. The frame member of claim 11 including a third surface extending from a first end to a second end, a lip extending outwardly from said second end of said third surface, said third surface and said lip forming a second recess. 13. The frame member of claim 12 wherein said second end of said third surface is located adjacent said first end of said second surface. 14. The frame member of claim 12 wherein said first recess is adapted to receive the skin member and said second recess is adapted to receive a barrier member. 15. The frame member of claim 11 wherein said first recess is adapted to receive the skin member. 16. The frame member of claim 11 wherein said rib extends outwardly from said first surface.
